42RLE Common Problems Transmission Repair Shop Can Fix Your Jeep Wrangler

Posted by Candy Lai on

Jeep Wrangler 42RLE also compatible for dodge charger, challenger, and ram 1500.
Rebuilt transmission is also common choice as brand new transmission price is way to high.

Top-6 Common Problems to Cause Transmission Repair 42RLE

1.Poor Shifting Problem
   Low transmission fluid majorly the reason caused your gear not move. 
   First step, most of time, you can check transmission fluid levels with transmission oil dipstick.
   Without enough fluid, the whole system could fail.
   Next could be Valve Body of automatic transmission. 
   If solenoid, in some car models may be solenoid block, got stuck in valve body, it will lead to computer malfunction.
2.Limp Home Mode or Gear Stuck in 2nd Stage
   Apart from poor shifting, losing car power and limp home mode is also common seen problem.
3.Over Drive On or Check Engine Light On
   Just like all the other engine problems, CEL on is the signal your car telling you something went wrong.
   Later on we have more discussion about error code meanings.
4.Grinding & clunking sound when shift
Manual transmission will have this problem more often as if clutch not release in correct time when gear shifts, transmission grinds.
This may cause wearing to synchronize rings and shifters.
If it sounds like buzzing, normally it may be the  bad bearing or leaking fluid due to bad seals.  
5.Overheating Transmission
42RLE seems to have overheating problem more often than other automatic transmissions.
Some suggest to install transmission cooler to prevent the problem.
Myself still agree that regular checking fluid level is pretty handy and practical way.
If burning smell appears, very possible the fluid leaking problem is happening.
Low fluid level causes clutch to have burning smell.
6.Revving High Engine
This is a sign that your clutches is wearing.
And if you feel transmission is slipping, check out the fluid level as well.
HJL Suggestion
Transmission fluid for Chrysler 42RLE shall be ATF+4 Synthetic 9602 Type.
Any additives should NOT be added into transmission system.
Well-known reason to cause transmission suffering issues are fluids except 9602 Type mentioned above is topped off replaced into the system. If correct Chrysler fluid is replaced properly, the system will work better and longer.
If you encounter your transmission stuck in 2nd gear, typically, soon transmission will go into limp home mode.
This mode is designed to allow you continue to drive the car to repair shop if Dodge Ram 1500 automatic transmission system goes wrong.
Thanks with this safety design, the transmission will not crash down immediately.
My experience is that correct fluid, clean oil, and proper fluid level are crucial to transmission system.
Never will be too much if you check it monthly.
