I've had that evil TC shudder for several thousand miles now and Dr. Tranny's snake oil has helped me delay the inevitable for quite some time, but this is the third time it's come back so it's time to do the deed. I can't stand the lack of confidence and performance any longer so it's time to fix the root cause.
Since I can't do any of the work myself, I'm going to take the car over to a local reputable shop and have them replace something.
I don't want to do a rebuild because it seems to be very (a) labor-intensive and (b) error-prone.
So I've considered getting only the TC replaced, or just getting a whole new transmission. I'm trying to balance cost and reliability.
I guess my questions are:
1) Can I just ask for a new TC or transmission? I don't think Ford just has new '97 4R70W's laying around, right? I definitely don't want something from a salvage yard because who knows what I'd be getting, and this is a major ($$$) repair so I'd like something solid. Would they have to get a later-model transmission and do some kind of conversion? And if so, what should I ask for?
2) Which would be best... replace the TC or the whole transmission? I suspect a TC replacement would be more labor... and I can't be guaranteed that something else in the transmission isn't ready to go (just replaced a broken accumulator and gasket). Which is why I'm leaning towards going all the way.
Just looking for some advice from people who have been there. I know where to get the best transmissions... they're just so far away.
