I have a 1995 Saturn SC2 and I am having an issue with the transmission. From start I can drive it down the road and it shifts through all gears fine. Drives for about a mile and then kicks down into low gear and will slip. It will not shift out of low after that. I can stop and shut engine off and restart and it will go through gears again then repeat. It does not seem like a loose connection since it is not unpredictable. It seems to go the same distance everytime before failure. I can unhook the trans range switch and it takes off in 2nd gear but will go through gears fine and never fails. I have done the following.
1. Changed valve body from doner car that I was able to test drive before removal.
2. Inspected wiring from connector.
3. Changed PCM
FYI the transmission was recently changed and this is when this issue began. I drove the car the transmission came out of for over 2 hours before installing so transmission was proved before installing. Could it be the Trans range switch?
have the same problem?
