View Full Version : 98 Pontiac Montana Transaxle Problems

08-21-2009, 12:44 AM
I've got a 98 Montana that was driving fine. No shuddering, no slipping, no nothing. I came home and parked in the driveway. Went back out to leave again 4 hours later and the Montana started up fine, put it in Reverse and nothing. No shift, no gerk, nada. Same thing for all the forward gears as well. The fluid looks good and doesn't smell burnt. I'm getting different trouble codes when reading the system with a code reader. The only one that comes up for the Transaxle was 1870.

One mechanic says its the Torque Convertor that has gone bad. Another one told me to disconnect the transmission line and start the car and see if fluid comes out. I did that and nothing so he says the problem is the Transaxle Pump.

I've replaced the Neutral/Safety Switch and the car still doesn't move. I didn't though pull the main a and b fuses to reset the computer. Don't know if that would help. Any suggestions or a place that I could get a Schematic for the Transaxle would be appreciated.
