So, my '01 GP GT has developed some shift issues.
At about 73k on the clock I have developed an intermittent hard shifting issue. I don't mean a big slamming lurch into gear. But, whereas shifts were normally very smooth and hardly even felt under light throttle, after driving about 20-40 clicks shifting will start to become hard, with a noticeable delay between one gear to the next and a noticeable jerk. It sometimes feels almost like it goes into neutral before it finally jerks into the next gear. Occurs in gears 1-4 and regardless of how much or how little throttle I'm giving it. Turning the car off for a while seems to "reset" it back to normal until I drive for some distance then it starts up again. It does shift at the correct rpm and I haven't noticed any slipping.
Fluid is "slightly brownish" according to my mechanic but doesn't smell burnt and is at proper level. I had him drive it for a while around the city until it started hard shifting and it came up with code for delayed shift and he said something about it compensating with max line pressure (Sorry, I forget the code number).
Basically, he says a fairly likely culprit is the pressure control solenoid, but he can't be certain. If I want he will replace it for about $500 (mostly labor) but he won't guarantee it. Alternatively he estimates I could just have the trans rebuilt for about $1600-1800 which will include a new PCS as well and be under warranty....
Any advice? At this point I'm leaning toward rebuild because if the PCS replacement doesn't solve it, I'll have just wasted like $400 in labor to drop the subframe twice and any other issue/parts will be fixed or replaced with rebuild anyway. Thanks.
