Give system voltage to the two shift solenoids. This will put the trans in 1st. The lever has to be in drive.

SOURCE: automatic transmission is stuck in 2nd gear (limp mode)

most newer vehicles  have transmission control modules,that go to a default of 2nd or 3rd gear when they go bad!  I had a 91 plymouth stuck in 3rd gear because of this module! could be your problem!    when mine went out, it smelled like something electrical burned inside the the passenger cabin! I would check all the electrical connections on the transmission first    good luck

Ask dealer if it has a towing package on it. If it does, you usually just pop fuse in under hood for electric brakes, and harness to adapt into is usually near or at rear bumper. Even if it doesn't have brake wire, you should still be able to install adapter at rear,for lights etc. which is available from dealer or auto supply places, then you may have to run electric brakes separate.

SOURCE: Wiring 7 pin trailer plug for 1998 C1500 pickup truck Z71

Here is some information that I find useful when wiring trailer connectors, and the brake controller should be wired into the vehicles wiring according to the instructions that came with the brake controller and that identifies each wire from the brake controller.

Be sure that you solder all connections well for the best operation, and you should use 10 or 12 ga. wire for the Pos. (+) connection, and the ground or Neg. (-) connection, and you should run both wires all the way out to the battery, and about one foot from the battery on the Pos. (+) wire to the battery, make sure that you use a 20 or 30 amp Circuit Breaker and Do Not Use A Fuse.

The rest of these diagrams should help you to get your trailer properly wired up.

I gotr a 98- 4L60E trans in limp mode & want to bypass neutral saftey switch. Can you help?


Bypassing the neutral safety switch won't help with the transmission problem. That switch is only wired into the start circuit.
Scan the computer for trouble codes. Has to be a code if it is in limp-in mode.

1996 gmc jimmy will not shift to 3rd gear


Hi, It may be in LIMP mode.

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.

Common failures on 4L60E, symptom any possible repair:

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.

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.

Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the trans goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either. R&R sooner rather than later.

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.

If you can get the Jimmy for no more then $500.00 and the engine sounds good and body is good, you may want to invest in the repair of the jimmy. Also note that to have a close look at the fuel line along the frame on the drivers side just by the back doors, the line is know to corroded there on all the SUV's

I just rebuilt my 4l60e and reinstalled and now i have reverse, manual 1, manual 2 and nothing more. there was a check ball stuck in the separator plate i just assumed it was stuck from trash or...


Note that many problems that show up as transmission issues are actually PCM or electrical, and may be external to the transmission. Try a different PCM, and check for chafing where the cables come out of the PCM.

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.

Limp mode 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.

Check the wire harness clip on the transmission, passenger side by the catalytic converter. Look for any damages due to corrosion or brake in the wire leads. it's common for the clip to brake and the wire harness to loosen causing the transmission in to limp mode. Good luck and keep me posted, be glad to help you get your transmission running again soon and please rate.

Check for check ball wear on the separator plate and address it if needed. The 1-2 check ball wears out and sometimes the check ball blows through or sticks in the plate causing troubles.

Just thought I would point out a few items to think about. Good luck.

1996 gmc jimmy won`t shift from 1st to 2nd


IF the abs dash light is on and if the speedometer is sluggish or not working at all, it is probably a bad speed sensor on the transmission. and easy fix under $40 for the part. Mine was stuck in second gear for a while then worked then it stuck in first gear and i had the CHECK ENGINE light on.

4L60E Shifts fine in 1st, 2nd, & 3rd but will not shift into OD


The EMC detected and problem so it's in limp mode, As long as it's in limp mode the 4th and OD will not activate. Take care not to burn up the transmission by running it hard while your in the limp mode.
Your going to have to get the truck scanned to clear any codes and why there are DTC codes. Auto Zone scan for free and most auto shops charge $10.00 to $20.00 to scan sine they want the business.
If you want to clear the codes your self you can put the ignition to the run position and pull the ECM (Batt) fuse out for 20 sec and place it back in then start the truck. It may stall but let it, just start it again and this would have cleared all the DTC code history.
The transmission should be running fine unless there is a problem and the service engine light will be on again and you'll be in limp mode still with an updated DTC in the ECM.
Good luck and hope this helps.
