For a while now my transmission has only been able to shift manually for about the first mile of travel when cold or if it sits for more than a couple of hrs.
I drove it that way for a while. Now it only shifts manually all the time and I have to shift from 2nd straight to overdrive. It won't shift to 3rd but stays in second gear until I shift to OD. Then I do have OD.
Have an 89 shorty, 3.0 with the a4ld tranny. Every once in a while, the other day being the worst, the tranny will not engage right away, not in D, and then not in R either... go back to D, wait about 20 secs, and it then acts fine.... but it's was a scarey 20 secs!
it only happens when it's cold, and hasn't been running... the fluid does need a change, and it will slip sometimes when it's warm in first gear, but not often. it's like a reddish brown color right now.
Is it time for a new tranny? or should I try to do a gentle flush on her first to see if that works... or just do a new filter and new tranny fluid for that... some people say it could make things worse, some say better....
I recently did a C6 rebuild on my 78 4X4. After the rebuild, when I go for a drive, the transmission does not AUTOMATICALLY shift out of 1st.
1. I can shift MANUALLY from 1st to 2nd with no problem, but it never goes into 3rd in D. If it was a system pressure issue, I suspect that I couldn't engage at all?
2. In Drive it just seems to be in 1st the whole time no matter how high the rpm.
3. I checked the vacuum at the modulator and I get 18 in .
4. I have tried every color modulator band and have the black one in now.
5. During the rebuild, I cleaned the governor, so I don't think it would be jammed up since it wouldn't shift even when I first drove it.
6. During the rebuild, I cleaned the valve body.
7. I confirmed the kick down is free.
8. I get a hard shift in reverse and from 2nd to 1st, but when I go to Drive, and then second, I dont notice a hard kick. Could it be that I messed up the orientation of the front clutch seal? (I hope this isn't the case!)
Here is the last couple of things I can do:
1. Could the intermediate band be the issue if I can shift in manual if it's not shifting hard?
2. The mechanic said it could still be a governor gunked up, but I'm skeptical since it never worked after the cleaning.
3. The filter screen pan from the rebuild seems to sit higher than the original that has a pipe that hangs lower. Is this the suction or the return from the system. If it's the suction I can put the original in.
Is it bad to drive her in manual if I need to? Obviously I'll keep the speed low since I can't get into 3rd. When I air pressure tested the transmission before the install, everything engaged like it was supposed to and all of my clearances were solid.
It's a 1988 with a 3.0 engine and an automatic transmission. It doesn't want to shift. I can make it shift manually, but if I leave it in OD, it wants to stay in 1st gear . If you fiddle with the accelerator, you can get it to shift. Then it wants to stay in 2nd, and so on.
Like I said, if I use the gear selector to manually shift, it will go to all four gears just fine.
My thoughts are a vacuum leak (a big one) or a faulty vacuum modulator at the transmission. No, the vacuum line to it doesn't have tranny fluid in it, but I replaced it, and I wonder if it's bad. Yes, I made sure to put the little metal pin/link back in it.
My 95 ford Aerostar 3.0 automatic trans wont shift into overdrive, here's what happened. a small hose on the side of the transmission came off, this must have popped off when I was stepping on the gas with the brake on in drive and reverse. It took 2 months to find the hose off, during those 2 months I had to shift the van manually, you had to get high RPMS before it would shift.
About 2 weeks before I found the problem I notice the van would not kick into overdrive. When I finally found the issue and reconnected the hose the trans shifted fine but still would not kick into overdrive though. Is there another vacuum hose that goes to the main vacuum housing? or an adjustment on the linkage area? This has been like this for about 6 months now and I can go on a highway..
A4LD transmission NOT RELEASING LOCKUP in both 3rd and 4th? My 1991 Ranger 4.0 will get into lockup sooner than normal(comparing the recent past), and would stay in lockup long enough to make the engine shudder when I slow down to come to a stop. (much like holding 4th gear without putting in the clutch when you approach a stop.
It doesn't die out and does shift into the proper gear but only after the RPMs dive down to probably 400 and the vehicle shudders a bit. Received and replaced the throttle position sensor today, looking to do the vacuum modulator this w/e. Any other possibilities?
At the beginning it was just CEL on. I checked the code and change transmission range sensor but it worked for few days only. Light came back and transmission sometimes stop to shift automatically. D1 on display and driving only on first gear, but when I switch to tiptronic - manually everything works great?!
View 2 RepliesI have a 1993 ranger 3.0L/6cyl/automatic/ a4ld. I replaced the transmission and torque converter with one from a salvage yard that has approx. 76k miles. I added tranny fluid and idled the engine for approx. 10 minutes in neutral, but the fluid has not begone to circulate. I pulled off the trans line at the radiator and there is no flow with the engine running in park. Where should I start with the diagnostics for this problem?
View 4 RepliesThis van has the A4LD transmission. I know nothing about transmissions, so, when it wouldn't shift from 1st to 2nd, or, 2nd to third, I researched it on here and found a lot of bad reviews. I also found out that it was likely the modulator gone bad, and how to replace it. I replaced it, and although the new one was restricted and the old one wasn't, shifting was back to normal. So, I was thinking, that was easy enough, pretty good for the original tranny which has 297,623 miles on it, and hasn't been serviced since the first 1k!
Well, that lasted about 75 miles. Now it won't go forward or backward. Everything is still in place, no leaks, fluid level is full. I didn't change the fluid or do anything other than change the modulator. (My friend can't afford to service it properly. Now it may need replacing!) I have only seen problems shifting between gears and OD, TC lockup, etc., but, nothing about not moving at all. What might be the problem? Is the tranny history?
I just picked up Aerostar #6 and am in the process of transferring parts etc. Got this one cheap as it was badly abused and has issues. Big problem, the shifter takes a lot of wiggling etc to get out of park. Is the interlock easy to disable? If so how? Or would a good column from my 93 be an easy plug and play proposition?
View 1 RepliesOk, my shift lever is broken where the OD button is located. Not the cap and button, the whole end of the lever has snapped off.
View 5 Replies95 3.0 aerostar. There was plenty of ATF in the vacuum line, hopefully this modulator replacement will fix the loss of ATF and will stop the oil from over filling, I had like 3 quarts above the dipstick line, I am assuming this was ATF going into the crankcase because of the bad modulator...
View 3 RepliesI have a 95 Aerostar that when in park it is hard to shift into reverse, drive etc. It is an automatic, 3.0 liter.
View 7 RepliesI was driving down the freeway the other day and when I hit a rough patch of road, nothing major, the truck sputtered and the 4x4 Low light blinked a few times on the console. I was driving in 2wd at the time. I kept driving and every bump I hit the truck sputtered as though trying to shift and the light blinked. On smooth road it didn't happen.
Today I drove to work at 6:30AM (40 miles), no issue. At noon I drove home and the issue started again. Every bump I hit the light came on and the truck seemed to want to try and shift into 4x4 low.
I got home, parked the truck for a few hours, then went out again, no issue. But about 20 minutes later it started again. I pulled over shifted to 4x4 high, drove it, was fine, went into 4x4 low seemed fine, went back to 2wd drove it some more issue came back. I've read tons of online threads regarding 4x4 lights etc, none like this and none on F250 Super Duty (2008).
Catfish is a '96 4wd extended doggie RV, with 175k. It has developed transmission selector problems in the last few weeks.
The shift selector stops seem to be going soft. It's not to bad going from P to OD, but I have to fiddle with the lever almost every time I put it into reverse.
Particularly harrowing when trying to do a quick turn around in traffic. What's going on here and what I need to do to fix it.
I have a 1991 Aerostar 2wd 3.0. I recently had freeze plugs replaced and the mechanic had to drop the tranny to get to some. Now the shift cable has come off the gear selector lever. I have googled everywhere and can't locate the procedure for reattaching it. My mechanic was doing the work on the side and charged me only labor for his assistant. He is at work right now..
View 5 RepliesThis is on my 7.3PSD. I've observed that the 1-2 gear shift drops about 1,000 RPMs and takes a good half second or longer to do so when given a lot of accelerator pedal input. And then the 2-3 shift is a very quick and harsh shift.
If I am accelerating gently the 2-3 shift is as unnoticeable as the 1-2 shift is quick. Is the slow 1-2 shift causing the trans to protect itself and affecting the 2-3 shift? And if so, what do I do to resolve all of this? I changed the trans fluid a week ago and there is no change.
I have a 1994 C-1500 4.3L with a 4L60E transmission. After driving for 30-40 minutes it loses 1st gear and you have to manually shift between gears. R, 2, D and OD can be manually selected but there is no automatic up or down shifting. There isn't any gear slipping prior to this. After sitting for 25-30 minutes everything works fine. I have noticed that sometimes before the problem occurs that if i manually select 1st gear it will stay in 1st & sometimes it will automatically shift to 2nd even though the gear selector is in 1st. Also it usually shifts into D at about 30 mph but sometimes it stays in 2nd until I manually shift down to 2nd and back up to D. It isn't giving any relevant codes (use jumper & flash codes). I'm thinking possibly faulty solenoid(s), but not sure.
View 2 RepliesMy '95 Aerostar 4.0 no longer likes to shift out of first gear. It will if I accelerate to maybe 25mph and completely get off the throttle for a few seconds. (It also revs freely at full-throttle kick down, as though it was in neutral.) A fluid and filter change didn't work, so I dug into forum posts. I found the vacuum modulator, and there's no ATF in the vacuum line, but it's an adjustable one which has me baffled...
The modulator has a thumb wheel on the outside of it. It will unscrew completely - and then it comes off, with a pin attached to it. This is very different from the ones I've seen pictures of here, where the pin is moved by the diaphragm. Is this the same pin, or some kind of preload device for the actual pin farther inside?
There's enough else wrong with the Aerostar that I'm not willing to sink very much more money into it. It'll run as is, as long as I'm careful. I'm just trying to get a few more miles out of it... might a regular, non-adjustable modulator?
I have a 94 ranger with the a4ld in it. When I bought the truck the trans was shot so I took it out and rebuilt it including new pump and torque converter. Now after putting it back in the truck wont move. so i took one of the lines off of the cooler and there is no fluid moving...?????what should i do before i cut my losses and blow the damn thing up??
View 12 RepliesGot a '94 Explorer 4WD that needs a new tranny modulator. Is there an easy way to get at it on the side of the tranny? The catalytic converter heat shield is in the way and I can't seem to get it out or gain access to the modulator area without removing the catalytic converter.
