Ok, some minor problems i have right now.
The passanger side door won't lock or unlock using the remote or the buttons inside the car, i have to reach over everytime to lock/unlock it, the drivers side works fine. Do you think this is a switch, blown fuse, frozen lock (just before it fully stopped working, it was on a freezing cold day and it started to lag a little before it went out)? I was thinking i might try opening up the door panel and using some WD-40, which im not even sure where would be the best place to spray it on...

Next is, the drivers door window keeps stopping on the way up, so i have to wait like 10 seconds to put it down a little bit then back up to get it to reach the top... I'm pretty sure this is the motor, if so i found motors on ebay for 40 bucks new.. would you recommend buying these and putting them on myself? Would this actually speed up the slow a$$ windows that most fbody's have? lol

I need to change my tranny fluid and i want to change my rearend fluid.. would you reccomend getting this done by a dealership or just do it at home. I read that i can cause problems to get a flush on tranny's w/ high miles on them. My car is a 97 TA w/ 80,000 on it. If you reccomend doing this at home, whats the best way to drain most/all of the fluid from the tranny?

Thats about it... cept for the low rpm hesitation which seems to be wayyyy too popular w/ lt1's. I think GM should make a recall about that problem, its just an annoyance. I have msd 8.5mm wires, ngk tr55 spark plugs, changed fuel filter, did recent oil change w/ coastal half synthetic, 170 degree thermostat from autozone cuz the car was overheating, took out the Airfoil that was kinda loose and came w/ the car when i bought it, cleaned K&N filter, Cleaned MAF, tested EGR valve which chocked the engine when i pressed it in (im guessing this means its working), i changed a bad 02 sensor with a boche one from autozone (that gave me a code). Thats all i can think of right now that i have done all WITHING THE LAST 1000miles or so... I wish there was a simple fix for this like the headlight motor fix

Thanx in advanced for any feedback.

 

I would change the window motor and lock myself. As far as the trans, if its not slipping now, or not too bad, leave it alone, changing the fluid at this point could do more damage than good.
