Ford Transmission :: What Is Excessive Shifting
Sep 27, 2012
is there any consensus on what is considered 'excessive shifting'?
i'm quickly learning that what i seem to think is excessive does not bother others. so i'm just wondering if there is any kind of science to defining "excessive"
i once counted upshifts and down shifts of my work truck (2010 f150, 6sp) and on a particular stretch of road it was shifting either up or down, on average, every 15 seconds (this was towing with the tow/haul activated). to me that was excessive. but the owner's manual says to use tow/haul to eliminate excessive shifting .... so by that, it must not be ... because tow/haul eliminates excessive shifting ...
so i guess, what do you all think? any kind of accepted definition to "excessive"??

I have a 2000 F150 5.4L with 157k miles on it. I think it has the 4r70w trans. The transmission has started holding 2nd gear too long before shifting into third. Throttle position doesn't matter, it does it even under light throttle. I do not have a check engine light. I have owned the truck since new and the trans fluid has been changed 3 or 4 times. The fluid looks pretty good now, not burnt or anything. The truck has been sitting in the garage a lot over the past 2 years, I drive it at least once a month and have put maybe 2000 miles on it this year. It shifts fine through the other gears, just 2-3 has an issue. Truck has the towing package.

I have a 2008 RX350 AWD with only 500 miles on it so far and I am starting to get concerned about what seems to be excessive slipping or a delay in response in the trans. Under normal forward driving the trans seems to shift very smooth. The problem occurs under situations where I am coming to a near stop, basically coasting, and then have to accelerate again to continue forward. This could be in a slow moving traffic type situation or when maneuvering through a parking lot. When I try to execute a small increase in speed the engine revs but the trans doesn't respond.
It's as though it's in neutral and unable to decide which gear it should be in. After a 2 to as long as a 5 second delay it finally engages and moves forward. The condition is even worse if I am heading into a slight incline. Once it is engaged everything is fine and the subsequent shifts are very smooth. When starting from a complete stop it works perfectly. I've never had a transmission slip this much in any vehicle. There was one situation where I was almost broadsided because the RX delayed in moving forward.
I realize this is a subjective call but I am trying to determine what level of slipping in the trans is considered normal under the conditions I've described. I have searched and read past threads about issues with the earlier model years but I thought they were resolved by now. I haven't taken the RX in for service yet but I fear I will get the standard - everything is working as designed - answer from my dealership.

Well recently i bought a 79 f150 4x4 with a C6. I have been going over the regular stuff like vacuum lines, fuel lines, etc. I replaced all vacuum lines because most were cracked or stiff or just falling apart. The problem I am having is that the tranny doesn't want to shift to 3rd. I replaced the vacuum modulator hoping it would work, but no go.
The old modulator had the adjustment screw pretty much turned all the way out, so I am guessing that was done to cover up another issue. The truck shifts smooth as butta from 1-2, but over revs and never shifts when going to 3rd. This happens manually and when it is in D. Could it be an intermediate band? I am new to the auto tranny world so I am trying to soak up as much info as i can.

bought the truck about 3 weeks ago and still having problems with the transmission. Replaced the VSS and it didn't work. My problems are it shifting hard from 1st to 2nd, it feels like it falls out of gear ( i can floor it and the speedometer creeps up then shifts hard.) Now i read having the 3rd brake light out is a problem with the trans too, my 3rd brake light is out along with the interior dome light ( doesn't go on when doors open) i plan to replace the TRS on the tranny tmw is there anything else i can do? how do i solve the brake light problem?

Have a 2000 expedition with 84,000 miles. Tranny seems to shift hard from first to second gear. Its been 24,000 miles since my last dealer tranny service. Thinking of getting a new service now before the recommended 30,000 manual recommendation. Whats happening?

I have seen a few threads about E4OD's and there valve issues just want to narrow down to a valve issue or if it needs a rebuild. I can shift threw all gears i just have lag going into 3rd. also when putting it in reverse it takes about 5 seconds to finally drop into reverse. This is also accompanied with P0782 2-3 shift malfunction.

I am having a transmission problem. I have a 76 F100 with a 300 and a c4 tranny. When I take off it seems to be shifting out way to early. It goes in to 2nd gear at about 10mph and 3rd between 20-25mph. I do have a kickdown linkage hooked up but I have not messed with any adjustments. The is a vacuum line that runs to the rear of the transmission. Also sometimes when shifting in to 3rd it seems to go in to neutral before going in to gear.

My 94 F150 has been actingup lately with the 4r70 transmission not shifting into 3rd gear or above. I replaced the MLPS sensor and re pinned the plug as per the instructions with the switch.The old sensor had the plug on the side, same type of plug, but wires indifferent spots. Truck wouldn't start like that, so repinned to match the instructions. I couldn't get the neutral mark to 100% line up as there is not enough adjustment, but it is very close.
The old plug had
32-298-140-33
57-199-359-463
I switched it to
57-359-199-463
33-140-298-32
Then tried
463-359-199-57
33-140-298-32
Truck still won't shift to 3rd, overdrive off button doesn't light up and itwon't start in neutral. I tested the ground at the connector and it lights up atest light connected to the pos bat cable with no issues.
Back up lights won't work, but flicker as going from R to N, so I suspect that is due to the fact I couldn't get the marks to line up 100%, but i'm not worried about that now.

I am going to look at a 92 Explorer soon and the owner says the transmission is shifting early.... I'm not exactly sure what they mean by it and I haven't gone and test drove it myself yet, I'm just trying to get opinions on what to look for and hoping it doesn't mean the end soon to come for this tranny. I was thinking maybe the vac. modulator could be the issue but I don't really know much about these Explorer's, as I've only owned one for about 2 months. It's a 92 4WD.

2005 Escape CD4E gone...157,000 miles. Previous owner said it was slipping when shifting to 3rd. During test drive the vehicle would hardly move. Only code was for the output shaft. There were metal shavings on the sensor magnet as well as the magnetic drain plug. The drivetrain is now out of the vehicle.
Questions:
1. After a bit of research it seems like there are a lot of tweaks that should be done during a rebuild to make this tranny live longer. Is there any point to having a local trans shop try to rebuild it?
2. Given the reputation of this trans I assume it makes no sense to look at used ones, correct?
3. Any other options?

Why does my C6 shift at 4000 RPM when the throttle is open? My motor produces peak torque at 5000 RPM, and peak HP at 6500 RPM.
I would like to have the lower gear until I exceed the peak torque at least.

My 1994 Ranger keeps shifting in and out of overdrive. It will go into OD easily, but it keeps downshifting, then shifting back up constantly. If I go up hill, if will downshift and stay in drive, but on a flat stretch, it wont stay in OD. It works fine when its cold, but after it warms up, then the shift problem begins. What do I do?

This has been a problem since I got the truck. It's a 1996 F150 5.8 4x4. It's got about 140,800 miles on it; had about 139,000 when I picked it up. Not sure if the trans has been rebuilt or not. I'm the 3rd Owner. It doesn't matter what temperature it is outside or how far my foot is down on the pedal... Just about every 1-2 shift is accompanied by a little kick/jolt. Going slow..(coasting, about 15mph) and it shifts into 2nd, usually the jolt is harder than hell!
Same goes for when I'm going about 25mph and I put the pedal to the floor It downshifts then comes back up to 2nd gear and wow. It jolts, shakes and shudders. Sometimes (rarely) I don't feel anything when it shifts. But it ONLY and always happens 1-2. not 2-1 either. Furthermore, when I go to put my truck into Reverse it kind of slams into it, with a clunk noise. All fluids have been changed recently and I also put "Lucas Oil Transmission Fix" in it and that didn't seem to change anything. What is going on internally?

I have a 1997 f250hd that shifts into 4th at about 25mph and lugs the motor down, then shift back to 3rd (maybe its 2nd and 3rd). It will keep shifting back and forth until you get up to speed, or if i'm in town i will put it in second.
No codes but the tranny fluid is dirty. I changed the filter the other day but didn't have time to flush it as it was getting dark and the line into the tranny was pretty rusted and starting to strip. Also there was no burnt smell. I'm planning on taking it in to have it flushed this week.

I have a 2004 Ford Escape XLT, auto,V-6, with 129000 miles on it. It runs fine except for a couple of things. One is, at highway speeds the transmission will seem to shift up and down. Also sometimes at highway speeds I get what I describe as a "bump" or "shudder" I think it is coming from the transmission.

I have a 2000 Ford Ranger 4X4 XLT with a 5R55E automatic transmission.
Coming out of a stop the truck jolts at about 20 mph as it shifts from 2nd to 3rd gear. It feels like it revs too high in 2nd gear, up to about 2400 rpm, and then shifts hard into third. It feels like the truck gets a gentle hit from behind.
Earlier in the week, the O/D light flashed. I took it immediately to an independent tranny shop who pulled the code for me: P7033, incorrect ratio in 3rd gear.
They cleared the code for me. In limited city and highway driving (less than 15 miles each trip) the O/D light has not flashed again. But the problem remains. I plan to take it back to the shop later next week.
What might cause this so that I might have a more informed conversation with the tranny mechanic?

2001 F-350 w/powerstroke. Tranny is the automatic w/overdrive. right at 170K miles and it has not been serviced since I've owned it (about 10 years).
Lately it is jerking when shifting, especially noticeable when I'm pulling my 5er (10K lbs). Almost a "clunk". No warning lights or OD flashing. I live at 6000 feet and play at over 9K so mountain driving is routine. Fluid is up to right spot on the dip-stick.

I have a 2000 V10 2WD Excursion with 104,000 miles. Last week it started shifting hard between first and second, but only when I am between 1500-2k RPMs. If I rev the engine higher, it shifts smooth. I checked the fluid and it is fine. I rarely tow anything except my little trailer to the dump every few months. I have a few questions:
1. Should I drop the pan and change the tranny filter?
2. Should/Can I check the rear diff fluid? (haven't noticed any leaks)
3. Could an inline flush and fill work?
4. I saw a post about a speed sensor in the rear diff. Could this be the issue?
