 93 probe gt trans issues.......
ok, here we go. I bought a 93 probe gt off of ebay. Drove it home over 150 miles with no problems, a couple of days later the trans started slipping. The first thing I did was have the trans fluid changed. Next thing I know I only have 2nd gear and the dreadded o/d light is flashing.
I bought an identical parts car ( crashed driveable car ) off of ebay and started reading about the problems alot of people are having with similar issues. First I cannot read the trans codes as they are the old eec4 codes and I cannot find anyone with the equipment to read the codes.
Next I started buy swapping the ECM/TCM with no changes.Then the speed sensor then the TPS, the TPS, and finally the tranny temp sensor inside the trans valve body. After all that I still have the same problems.
At this point I am readdy to change the tranny. It just seems to me to be an electrical issue more than a mechanical issue as it has plenty of pressure in 2nd gear and it dumps the pressure off when put in another gear like it is getting bad readings from somewhere.
Is there something else that could be giving bad readings as I am out of ideas and going to swap trannies soon. thanks!!!! |
