Lustalbert Posted September 11, 2006 Report Share Posted September 11, 2006 Wife GP is surging, starts out fine, however mild acceleration from ~35 - 60 yields a surging in the RPMs (aprox 500-700 rpm variance). Kind of like the torque converter is cycling in and out of lockup. Also, there is a fair amount of whine when accelerating, almost sounds like blower whine. Shifts firmly, fluid level is good, fluid looks good and smells like tranny fluid should. The car is in good shape, nothing else mechaicaly wrong, 120k on the clock. Anyone have some ideas?

Bam Posted September 11, 2006 Report Share Posted September 11, 2006 My car would do this and I too thought it was the tranny locking/unlocking, it ended up being the fuel filter. It got so bad the car would stall out in the city. It was an 01 gtp, changed that and it ran perfect afterwards. Quote Link to comment Share on other sites More sharing options...
Buck531 Posted September 11, 2006 Report Share Posted September 11, 2006 Change the plugs/wires. If that doesn't do it. The converter is probably going. If it's NA, I have a stock L36 converter at the house I'd let go cheap . Quote Link to comment Share on other sites More sharing options...

caseyctsv Posted September 11, 2006 Report Share Posted September 11, 2006 I have a 99 with 135K on the clock. My car does the EXACT same thing. Let me know what it ends up being!! I think it is the convertor. Quote Link to comment Share on other sites More sharing options...
grease monkey Posted September 26, 2006 Report Share Posted September 26, 2006 My brother purchased a 2000 GP, 3.8 like 85K blah blah blah... Well it started doing this as well, took back to dealer where was purchased, they said it was an ignition missfire. So 450 bucks later (and me yelling at dad for paying that when his eldest son is a mechanic) 2 new coil packs, plugs, and wires it's still doing it. Took said car back to dealer, the DEALER techs can't find the cause. Find some TSB that was "slightly" relavant to the problem, and replaced the TPS. Big surprise, car was still doing it. Well marc was with out car for about a week, when he decided to trade it back in and get something else. About 2 days after Marc picked a newer, much more expensive pre-owned vehicle, the "factory trained" techs figured out the problem. The torque converter clutch solenoid was faulty inttermittently, which is what I had suspected all along, and TOLD the dealership. But no one listened to me. So The torque converter clutch solenoid is also something that you may want to consider. Quote Link to comment Share on other sites More sharing options...
Duff1647545513 Posted September 26, 2006 Report Share Posted September 26, 2006 My car would do this and I too thought it was the tranny locking/unlocking, it ended up being the fuel filter.

Mine's doing the whole stalling out thing right now, put new fuel filter in and it still does it. Could it need a new fuel pump too? Quote Link to comment Share on other sites More sharing options...
