Ferrari :: Transmission Would Crunch When Engaging Reverse
Jan 22, 2011
In today's show, a caller with a Ferrari noted that sometimes the transmission would crunch when engaging reverse. I've never had the pleasure of driving a Ferrari, but two Porsches I owned (in my single days) had similar issues. There is no synchro for reverse gear.(Ferarri may be the same) So if I idled in neutral to get the gears moving and then shifted to reverse quickly, the gears would crunch as they meshed. A little drag from the clutch not disengaging completely or the pilot bearing dragging would make it worse. Two solutions are
1)let the transmission coast down by holding the clutch in for a few seconds before engaging reverse, or
2) shift to second, then straight to reverse.

Just recently, my '93 transport 3800 has started making weird sounds when engaging transmission , forward...and specially reverse. This is not a transmission problem. It sounds like there is increased torsional movement of the engine/transmission unit and it made me take a look at the engine while would shift in drive and reverse....it does lean much..impressive ..but in fact I do not remember having tried looking for that before...so I cannot compare.

I replaced my rear pads on Sunday and the car drives and brakes great. This morning I noticed when I backed into my parking spot at work that the brakes were engaging to the point where I was on a small incline and the car didn't roll at all when I let off the brake pedal.
This was my first time doing the rear pads on my MKVI and my first time doing brakes on a VW. Is there some extra step required that I'm missing? I know the piston was a PITA, definitely not used to having to turn a piston while compressing.

I've started noticing this only when she's cold and I have to back out of the garage in the morning. I generally wait 5-10 seconds after I start the engine before going into reverse but lately I've noticed a muffled metallic 'pank' coming from the engine compartment when the reverse gear engages. I can't say I feel any 'thump' to go with it and I'm racking my brain to see if this is a new development and I have a possible transmission issue or if it's been there all along and I never noticed.

I have a 2015 with 10k miles on it and every once and a while, when I come to a complete stop and shift into reverse, I take my foot off of the brake pedal and the car will sit there for up to 5 seconds. Then, it kicks in and starts rolling backwards. This has happened 6 times now. Giving it gas doesn't seem to work along. I took it to the dealer today for it's 10k service, and they cannot find anything wrong with it. There are no codes in the computer, the fluid is where it should be, and they think the Neuspeed Power Module has something to do with it. I told them it happened before I installed that piece. I can assure you I am not racing in reverse.

When I reverse (and wait 3 seconds just to ensure the gears are engaged), on occasion I feel a stutter/kick.
To offset it, I will tap the pedal when reversing so its not continuous. What this could be?

I am having a problem with my MKIV, @ 182k. I think problem first arose a couple months ago when reverse began not engaging on cold starts, so I would have to sit there 5-10 minutes waiting for car to 'warm up' enough for reverse to engage. This led me to taking it to a local tranny shop who I asked to change fluid only, which they did. Problem persisted however, but forward driving was noticeably much smoother. If that matters. I gave up on it, since I knew it was only reverse messing up, and started parking in reverse overnight etc.
Simultaneously I had a code for P0420/P0411 (the SAI incorrect flow crap which causes catalyst inefficiency) so I went ahead and swapped out the cracked SAI plastic hose leading to stock airbox, after doing so I reset the CEL and ran the car. And it ran like crap, I think it was in limp mode (i had never experienced this in my Jetta) from what Ive read, but not sure. So, I pulled to the side, and restarted car, let it sit, same problem. Finally, after 3-4 cycles it threw a CEL, which ironically FIXED the problem. It ran fine from then on. Made it home, hooked up scanner and CEL code was P0732, which I read elsewhere is a 'Gear 2 - Incorrect Ratio' meaning 2nd gear is messed up somehow.
So, overnight I reset CEL and today in the morning I let it idle for 10 minutes before taking off, immediately same issue, where car will not accelerate/ change gears it seems. Went back straight home, waited for CEL to display, and VOILA, runs fine again. Same code P0732. Running fine as of writing this. Problem only arose after taking a swing at SAI code and reset of CEL's. Once CEL lights up its fine.

I've noticed an intermittent clunk which occurs when engaging the hydraulics brakes during reverse maneuvers. It happens with anything from very light to very heavy brake force and typically will happen before driving very far (backing out of driveway, out of parking spot, etc) but does not happen after driving (backing INTO driveway or parking spot). This has been occurring for a while now with no other symptoms (other than some shudder during take off which I attribute to a sloppy transmission bushing).
Front brakes were in great shape when I r&r them a while back to turn the rotors, didn't pull the rears apart but they look good, and I don't have any brake vibrations or issues when moving forward. I can't rule out a driveline clunk or suspension clunk either but the u-joints don't have any slop in them and no squirrely handling issues either.

I have a 2008 F-150. When moving gear selector from park to either reverse or drive, trans has a delay engaging. After engagement, it runs fine, shifts ok, downshifts ok....

I have aproblem with my 2007 Camry 2.4 SE automatic tranny at 88000 miles. I parked my car as usual,got back after 2 hours started the car normally pressed the brake pedal to engage D and....nothing happens. The lever moves freely from R to L but the light on the instrument cluster stays at P and the car won't budge!!!!! What could be the cause.
The tranny showed no signs of failure before,excpt a slight vibration while in Drive. What I should go checking before towing the car to dealer.Any fuses relays etc.?I mounted a back up camera lately and had to slice back-up wires in the trunk to do that ,could this be related?

I don't know if this all started right after I got back from towing a 3500# lathe + 2000# trailer back from Texas a couple weeks ago or if there might have been some slight symptoms before. I do know that this really got bad a couple days ago and I haven't driven the truck since then.
So, here's what is happening. I noticed a few days before that when I would back out of a parking space, the truck didn't seem to go right into reverse. It was as if it was in neutral, but as I was reaching to jiggle the gearshift lever, it would engage and I could back out just fine. All forward gears, and shifting, have been fine all along, including lockup. I kind of wondered if the shift linkage had somehow moved and was on the edge of being in the right spot, so I was going to have a look at it one evening soon. Then a couple days ago, I went to back out of a parking spot at work and it wouldn't go anywhere.
Just acted like it was in neutral. Put it in drive and it engaged just fine, then back to reverse and nothing for a few moments before it finally engaged. Then, as I was backing up, it acted like you might expect a limited slip that was not slipping to behave. But, that was right before I put it in drive and went home. After I got home, I tried it out some more and found that in reverse, it just wouldn't go anywhere unless the truck rolled a little bit. I don't know if the rolling really had anything to do with it or not, but the driveway is on a slight incline, so it happened, and then the transmission would engage. But, when it did start to back up, even straight, at first it acted like it was under a load, then when it started to move, it bucked really badly. Put it back in drive and all seems fine.
There are no codes set. Trans fluid is full, and doesn't smell or look bad. I've searched for reverse shudder, and other stuff, and there are threads about the TC, about no reverse at all, and a bunch of other stuff, but nothing like this that I found.

I got a 99' Jetta gls 5 spd. I just replaced the transmission and now the car won't engage reverse from inside the cockpit. Reverse can be engage from inside the engine bay, but when the shift knob is depressed nothing happens. Linkag cables are in the correct spots.

2009 Camry SE 2.4L. I have been noting an unfamiliar vibration of sorts in my gas pedal for some time, but did not notice smells, overheats, noises, fluid loss, DTCs or anything. Today on my way to work I started to notice hard shifting. The RPMs would rev up, fall down and shift hard. At time the RPMs would climb to 5k before dropping back down then shifting. Got worse, then finally when I was trying to U turn across the road (was stopped in gear) I lost all gears. I could shift to any gear, engine RPMS would remain stable, but no movement. Pressing on the gas just hiked the revs.
I pushed it off the road, and killed the engine and could get it to engage for short periods then no gears again. Seems like if I let it sit for a bit it will work for a short while, then no gears again. Had it towed home. Trans fluid indicates full, no burnt coloring or smell to it. No indications of leaks. After the tow I was able to drive it up into my driveway.
For clarity, I can move the selector to any gear and that feels normal. The engine does not bog down. I simply am not engaging any gear. Thinking sensor? Maybe heat related?

My transmission had no slipping was running fine . Oil level was ok , recently added 1/2 quart , cause it has some small leaks. I go to drive away other day and none of the drive gears or reverse would engage. Mechanic thinks transmission locked up . Kind of hard to condemn my old baby considering it was running fine .
Would the TCC solenoid do this or the ECU ? I recently reinstalled the bar going to starter that was disconnected for 5+ years because i was having slow crank issues. This transmission problem occurred 2 days later. I am thinking it might have made the ECU unit go bad , since the starter had not a good ground for so long ?

I recently bought 2007 ES 350 drove @700+ miles, 2 times I had this incident in this week, the latest is today. In cold morning when I try to drive the vehicle when it is cold when I pull the lever to drive mode the accelerator increases the RPM but the car is not rolling or I should say very very snail pace, so I tried pushing the lever back to park, then reverse drive the vehicle and then engage to drive mode it works fine but I hear lot of fan sound. For initial few min I feel that it is not picking up much speed but then it becomes normal. It really tensed me. What action can be taken to resolve this?
As per the Autocheck report this was manufactured in Jun 2006 and the vehicle service records from Lexus web there is no sign of any transmission problem or fix to transmission. The car has 100K+ miles on it.

2004 Dodge Stratus 80K... What happened is my check engine light came on maybe 6 months ago and I took it to have it looked at and they were closing but the guy told me don't worry about it and I be ok until I come back and it probably wasn't a big deal. The light went off a day or two so I didn't worry about it. It came on about a week ago and I haven't had time to take it in yet. So here is the chain of events-
Check engine light (6 months ago approx)Check engine light off (couple days later)
Check engine light (1-2 weeks ago)
Put my car in drive, transmission didn't engage right away. I thought I had it in neutral by mistake. then it engaged.(about a week ago)
Same thing happened last night except it took longer for it to kick in and when I ran into the store and came out, it backed up ok but wouldn't go in drive right away. I thought it was because it was freezing) out and maybe needed to warm up better. (we had a terrible ice storm here in Washington).

I need to decide what to do with my transmission. I just acquired a 2007 F150 Supercrew 2WD 4.6L truck with 184k miles. While in Drive the automatic transmission (4R75E) runs ok thru 2nd gear and then; if O/D is on it will rev without engaging and if O/D is off it will just stay in 2nd gear.
I was hoping the problem was a broken retainer clip, as are so many others. So I removed the pan, and the valve body. All of the retainer clips seem to be fine, but, there is a lot of metal sludge on the magnet of the pan. See pic.
Should I buy a complete rebuild kit and take the tranny out of the truck? Is it just a problem with the valve body? I need to get the truck going so I can get to work. I am uneducated in the transmission department.

I just installed a rebuild 4R100 transmission in my 2001 4x4 Excursion with the 7.3. I'm having trouble getting it to engage into gear. As I shift it into gear it sounds as if it wants to engage but doesn't. I have checked the fluid level and it at a normal range. I'm wondering if I didn't put enough fluid in the converter would that cause the problem.

I've got a 1982 Courier 2.0 2wd 5speed pickup and it's been passed down through my family and has sat for quite a while so I started tinkering with it in my spare time.
I began with the motor and got it to run after 15 years of sitting around but am having issues with the transmission. When I first got it running a while back i had it in gear and when I let out on the clutch it lunged forward a little and stalled. I have since then towed it a short distance across my yard (in neutral of course), but now it seems like it isn't doing anything while it's in gear.
While its running I can put it in gear (even without the clutch) it doesn't grind jump or anything. Everything feels like it's okay as in going into all the gears. I was wondering if this is possibly clutch related or if it's the trans itself. Or maybe some electrical thing related. I haven't taken anything apart yet in hopes that it's something simple. I was curious if it might be low on fluid and maybe that would cause it not to engage properly?

My '05 F150 (92,000 mi) 4 wheel seems like it is engaging and disengaging when activated. Makes a clunking sound on light acceleration then quits when I back off the gas. Not sure if it is engaged then or not. I noticed this on a gravel road when I had turned 4x4 on to distribute oil around the system since I had not used it in a while. What it might be and if it is any easy fix or a trip to the shop.
