difficulty level depends on how well you can use tools. if you're really handy dandy you can have that SOB out, rebuilt, and reinstalled in a matter of days. if you want to go for quality you should take your time, i can get both because i have rebuilt enough of these that i found out little tricks to the trade. anyways, new converter can be solved here and now... just get the CR63 from autozone. it is a proking converter, i use it on my van and have towed 32' travel trailers, pulled cars out of ditches, pulled pilings out of the ground, floored the gas pedal numerous times, brought the vehicle to speeds of 100 MPH and have held for over half an hour (valvoline is why my engine still runs, next to that it is the legendary 318).
as for the rest of the parts you need it is going to depend on many factors. you need to tell me what you want, if you want just a plain old stock rebuild or if you want to add a little meat for longevity?
if you are looking for longevity expect to pay a little more, for example 200 bucks for the clutchs alone! you could potentially buy a stock rebuild kit for that price... but again, longevity. the stock friction discs actually are very good. it is those plates that burn up and the hydraulics that cause the issue. allot of shift overlap with the 2-3 shift which causes rear clutch failures. that can be cured with the sonnax front piston assembly. you also have numerous cooling mistakes. no fluid flow in park and that shows up on the input shaft bearing. sonnax makes a valve that will allow flow in park which extends the bushing life. so much to list i could write a book. you tell me what you are looking for and how much you are willing to spend and i can come up with a parts list from a supplier that i trust. as for the tools and knowledge i will help you with the required tools and where you can get some of them along with the help to rebuild it. if you have really good memory you won't need me when it comes to taking it apart and putting it back together. oh and please know that the tool cost can get expensive because you will need a small shop press to rebuild the overdrive unit. you will also need to get a yoke seal, a specific one that will not back out of the case like mine has twice at 98MPH and i lost allot of fluid that way. you will also need the usual loctites and crap like that.
yea. just get back to me on this. if i do not respond please understand that i am in engineering school and usually am very busy but i will try my best to help you out.
