Subject: 95 Eclipse Transmission Gear Changing problem
Question:

Couple months ago, I got into an accident. When I drove home from the towing, my car was changing gears perfectly. After the car was sitting awhile, and after I fixed the cooling system (from the collision: radiator, condensor, fans), the car had gear problems.

It goes from 1st gear to 2nd gear fine, but then it gets stuck in that gear, and can't shift to the next one. The RPMs keep going up, and no gear change.

As I said, it was driving fine before I started fixing the cooling system, but now the gears don't change properly. By the way, WHen I was fixing cooling system, some trans fluid leaked, so I added more. My next step is to replace the Trasnmission Filter.. But what if the filter doesn't help, what could be the problem?

Answer: Yuriy,
It's possible the gear cabling became misadjusted during the installation of the cooling system. Be sure all the cables are properly seated on the transmission and it has the proper level of fluid in it. It may just be a coincidence that the transmission started showing problems after the front end damged was fixed. It is a good idea to drain the fluid and replace the filter to be sure this is not just a simple fluid problem, but if the problem persists afterwards, you may need a transmission shop to inspect the problem. You may even want to consider having a tranny shop inspect your transmission first, since they may have to drain your tranny system any to inspect it.
Good luck!
