Angry 1999 gtp problems

I have a 1999 gtp idling issues, no forward movement what so ever, only reverse, replaced fuel pump, still have to bend the tab out, trans fluid change and filter, right before it went, started it the other day after sitting due to the trans being fucked. and it ran good until it started smoking from the intake manifold it seemed, white smoke, ran for about 30 mins and started idling like **** and completely died, lights dim in and out all the time, needs front right rim and front right wheel bearing hub, right front door and fender and the bottom skirting on the right side, needs a new shifter because i have to press the neutral button to get the shifter to move nothing but problems, looking for cheap places to find parts and fix. found a used 4t65e-hd with 92k and was wondering if i should replace the sensors in the used trans, add a transgo shift kit and another magnet and or any other things i could do to make it a reliable refurbished trans, the shop said it was tested and worked, but i wanna prevent any future trans replacement, and make the car reliable as hell till i can buy a new one, love the car just problem after problem, looking for solutions to all the problems and making it a reliable daily driver

Make sure the transmission is the proper final drive ratio. As far as the smoke and running bad have the lower intake gaskets ever been replaced? Very common for them to blow out and to ingest coolant into the engine. Your transmission might not be that broken. The forward band is known to break the mounting lug off causing no forward movement.

You need to look at the last four digits on the broadcast ID tag on the transmission and make sure the replacement transmission is the same.

Here is a reference chart for a 99 year model.

You can also pull the spare tire cover off and look for the sticker with a list of three digit codes and see what your car came with. Look for the codes that start with F.
FR2 Ratio, Transaxle Final Drive, 2.93
FR9 Ratio, Transaxle Final Drive, 3.29
F83 Ratio, Transaxle Final Drive, 3.05
If you know where the car the replacement transmission is you can look at its RPO codes as well.

you cant do a trans with no tools and no jacks. your better off finding someone to rebuild it. i do have all the tools and have done it many times, and i still have it rebuilt, because you are money ahead when the used trans goes in a few months after the warranty expires, and they always do. they are old and if they work when pulled they dont like sitting waiting for someone to buy them it gums them up. best thing you can do for someone who has limited tools and funds is search around for the lowest price. i just had my bonnie done for 800 plus parts which is about 1000 total. thats pulling and installing it themselves

well my plan was just to use the trans from the scrapyard, it'* tested and has a 100 day warranty. but my plan was to just swap it with the used one and rebuild the old one while it sits and when the used one goes swap it back with my rebuilt. just wondering if 250 for the trans with 92k and 250 to put it in is worth it? also wondering if there is any tweaks i can just do to it to prolong the life of the new one shift kit, better clutch hardened 4th gear better bands, thoughts and opinions would be great on this!

IMO i wouldnt spend 50 bucks because whatever you spend is wasted money. as far as rebuilding it yourself cant be much help ive only done rear wheel drive ones. but you cant do either without jacks, jackstands, and that one i think requires a real long extension for the rear bolts.

here is a thread with some of the tools just to get it out.
