Hey guys,
My car (1993) has 175k, and the tranny is on its way out I think. Starting out it will rev past where it used to shift into 2nd, and you have to let off the gas completely to let it shift. I am thinking it is probably the one way clutch from the reading I have been doing. The Jerry article on tccoa really makes it sound like a 4R70W from a 5.4L truck is the best option. But you have to swap a valve body from a car (preferably 99 and up) to the trans to make it work. I priced a new valve body and they are $250. So, I am trying to decide what to do and wanted to get some opinions. I am also going to be getting a new torque converter so the price for all this is going to be a bit higher than I was hoping if I go this route.
First, are there any sources you know of where I can get a valve body, maybe used but not abused for cheaper? Second, how much better do you think a truck trans would be? Third, would it be bolt my 1993 valve body on there? The future of the car probably holds 4.10's and a driveshaft, chip, maybe a small NOS shot but I doubt anything extreme. On Greenleaf, I am finding transmissions from Mustangs, Grand Marquis, etc. with about 10k for around 8-900 bucks. My main goal is to get something in there that will give good performance and last another 100k. And I do plan to do a jmod to the separator plate.
Here is a rough breakdown:
trans: $900
converter: $800
valve body: $250
What are your thoughts?
