Shift module


That transmission is one that has been used for years in Dodge and Plymouth vans. Do you know when the last time was that the fluid was flushed out and replaced? It's pretty important that it be done every 90K miles.......have it checked out.

AUTOMATIC TRANS


on automatic transmissions Ok,1st check the transmission fluid level if low or if any at all, 2nd you might check your trans shift solenoids, or the wiring to the solenoids verify which solenoid you might need to replace by google it can show you a location of the 2nd and 3rd. If this doesn't cover the issue the next step is a tech to work on the transmission cause it could be and internal issue.

I have a 1993 f-250 u have to manually shift to 1st to take off shift to 2nd and still in 1st gear. Shift to overdrive and transmission will shift through 2nd 3rd 4th and then to overdrive with no problem....


When was last trans fluid & filter change? Should be done every 30k/3 years or sooner of you do any towing. I'd start there and get it flushed thoroughly.

Manually shift thru all gears up & down the scale. Try adding Motorcraft Additive Friction Modifier, available from Ford parts dept. This REALLY STINKS!!! Don't get any on you. Pour into trans fluid. Drive a few miles shifting manually thruthe gears, then do a normal start stop drive several times. This will luburcate trans, normally used for differential but has worked in automatic transmissions of all makes for years. Otherwise mechanical problem for transmission repair facility.

My GMC has 311632 miles on it. I just changed the 4L60E transmission a few months ago and now it wont shift out of first unless I manually put it in second gear. all the gears from park rev. nuetral works...


The transmission may be in Limp mode. The transmission is on the same fuse as the MAF, O2 sensors and at least one other sensor - if an O2 shorts out, it will blow the fuse and the trans will go into limp-home mode. Be sure the trans has power and the fuse is not blown before doing anything else.

What is "limp-home mode" ? This is a fault mode in which the transmission either loses electrical power or the PCM deactivates all of the electronics. The transmission will default to max line pressure. The driver will have Reverse and 3rd, with manual 2nd available by putting the gearshift in 2 or 1 (doesn't matter). 1st, 4th, and TCC lockup will not be available. It will not hurt the car to drive it like this for short periods, but use manual 2nd to get the car moving, and be aware that the trans will generate more heat than normal while operating in limp-home mode due to increased torque converter slippage during 2nd gear starts and no lockup in 3rd gear.

Trans does not upshift out of first, speedometer reads zero at all times: VSS failure. Easy fix on rear of transmission, but xmember must come out to access VSS.

Car goes into gear but feels very sluggish like the brakes are dragging, but it will roll easily (starts out in 4th gear), you manually shift to 2 to get it moving, once it's moving you put it back in OD and the car shifts 3rd to 4th on its own and locks the converter at the appropriate time: ShiftB solenoid failed: Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

Transmission does not shift automatically, only manually. Swap in a known-good PCM, check wiring, check other sensors such as VSS and TPS.

3rd gear starts, can manually shift through all gears. When car has been turned off for a bit, then back on it will run normally.: VSS dropoff w/ Hi-stall converter. The rpms are too high, but VSS is showing no movement. Happens after a tire burning take-off. Doesn't store a code, will not throw a CEL (I've heard that it will store a code if it happens 3 or more times). Cure: Reprogram PCM for VSS dropoff -- PCMforLess knows about it.

Here are just some of the common things you have described with the issues your transmission has. Good luck and keep me posted.

Trans shifts into gear harshly, car feels sluggish off the line, No 1st, 4th or TCC lockup available, Manual 2nd, 3rd and Reverse are only available gears, CEL is on: Transmission is either in limp-home mode or has lost electrical power. If there are lots of error codes in the PCM, check the under-hood fuse that powers the transmission, and if it pops again, look for a short in that circuit like an O2 sensor harness touching exhaust. Otherwise, check PCM codes for a particular fault in the transmission causing the PCM to put it in limp-home mode.

No 1st or 4th available; trans shifts 2nd to 3rd by itself in D or OD and locks the converter : ShiftA solenoid failed. Easy fix in the pan. Or a wiring problem from PCM to trans.. or PCM.

93 ford probe jerks when going into 2nd


Don't know if this will be of any help, but these cars have the same auto trans as the Mada 626s of the same age and they are a problematic transmission. They tend to blow up. Gerking could just mean it needs a service. ie: low fluid levels or 'worn out' fluid. It could also be an early sign of bigger problems.
We ended up selling our mazda because of the transmission. around $1800 to replace with reco but many people reporting reco trans failing within 2 yrs anyway.

Manual transmission light flickers off and on-car won't go over40


Is the car a manual or automatic, 4 or 6 cyl? If it is a manual trans the hard shift could be due to worn shift forks which were rather common in these cars, had them go out in my 90 GT a few years ago. Could also be low on lube or the wrong lube. To check the lube on a manual trans car remove the speedometer drive which is on the top of the trans. The fluid should be at the bottom of the gear on the drive. The proper fluid is ATF not heavy gear oil that ends up getting put in. Hope this helps

Auto Transmission


Try shifting the trans manually through the gears and see what happens,doesnt cost anything so,possibility valves are sticking in the valvebody after sitting so long,and manually shifting the car will force some of them to stroke in their bores unless REALLY stuck.Could also be shift solenoids.Scan for diagnostic trouble codes.A bad solenoid will have set a trouble code.Just FYI,1991 was the first year Ford went to all electronic trans,i had a 91 Sable.
