A 2002 Chevy Express stalling only in reverse could be caused by several issues. Common culprits include a faulty transmission, issues with the torque converter, or a problem with the idle air control valve that affects engine performance under load. Additionally, a dirty fuel filter or a failing fuel pump could result in inadequate fuel delivery when the vehicle is in reverse. It's advisable to have a professional mechanic diagnose the issue for an accurate assessment.
There are several reasons that a car may stall only in reverse, the best way to narrow down the issue is to use a diagnostic tool. The diagnostic tool will show which sensors on the transmission may be malfunctioning enough to stall the engine.
Sometimes the torquconverter can fail causing the engin to stall. In reverse it lock in full torqu. In fwd gears it slips. This is only one idea.
This happened to me on a 1986 cutlass 2.5. A wire was shorting out going to the map sensor and only did it in reverse. The bracket on the alternator had rubbed a hole and only grounded when the motor moved, when placed in reverse. I fixed it temporary with electrical tape.
I'm no mechanic, BUT that happened on my Taurus when the fuel pump was not functioning properly. Best to take it in.
Every time you start the engine, SRS(airbag) performs a self test for a few seconds. On a Chevy Express the light should only be on when there is a fault, and turn off once the fault is fixed.
The input sunshell splines have stripped or the hub has broken off. This will give you 1st + 3rd gears only with no reverse, 2nd, or 4th gear.
you have a problem in your torque converter or transmission pump
Your tranny is in limp mode. The only gears that work are 2nd and reverse. Check the cable to your tranny and see if it is plugged all the way in. If it is then you have other electrical problems and need to have your truck looked at.
Your motor mount is broke on the passenger side replaceit and your trouble will be solved
I had that issue with my Cavalier and it turned out to be a fuel pump problem. I would check with your local mechanic.
reverse gear going out is a good indication the rest will go out soon. yes you need to change entire transmission, or have your transmissin rebuilt. a mechanic will not just rebuild reverse .it will be complete rebuild or replacement
I believe there is a ring right below the the shift knob. pull up on that ring and i believe reverse is all the way to the right and down. i believe only newer cavaliers had this feature.
