Auto Trans Slip?

[pointblank9957]

i have a 98 Eclipse GS Spyder, recently the trans started to feel like it was slipping, i can take off normally and the revs can keep climbing but the car wont go any faster. the tranny fluid doesnt appear to be burnt or low, the CEL isnt on. the car also runs really rich from a dead o2 and no cat. any suggestions? also combating a dying alternator.

Fix the problems you know you have. I'd be very reluctant to drive the car at all with a dead front 02. Additionally, it's common for a DSM alt. to fail in a fashion that overvolts the battery and subsequently the wiring and devices attached.

I hope an auto guy chimes in to help you but when I hear things like bad alternator and symptoms that could be considered electrical, I think about deep fried TCU. It won't hurt to inspect it.

EDIT: sorry, thought it was a gst instead of a gs.

rear o2. i dont have a front o2. i'm workin on the current problems. the alt didnt spike the battery, the voltage stays around 9-10v. its not even enough to crank the engine, so i have to bring my jumpbox everywhere

i've been under my car when it was up on a lift, there is no first o2

Are you checking the ATF with the car level, at normal operating temperature with the engine running and the transmission in neutral after shifting through each gear?

If you do it wrong the level will read normal when it is actually low.

If the slipping stops after driving for a while then low level is confirmed. The ATF expands when it gets hot.

Turns out it was the Alternator, it wasn't providing enough energy to the coils to make a good enough spark to combustion completely.

I thought that was figured out in October!?

9v and all..
