Transmission Woes Options

[Javve]

Engine info in Sig

Transmission has a leak. It will not shift right. I have to go 3K to 4K rpm to get 30-35 MPH. I am guessing the transmission needs an overhaul?

I also noticed that I have to make sure the shifter is all the way up in P for it to start.

I don't know about the automatic for sure, but I know there is a different ECU for the automatic and the manual. But I don't see why any sort of controls would make anything 'not worth rebuilding'.
Of course when you're taking it to a shop ran by people you really don't know They would no doubt charge you a ridiculous amount of money to rebuild it. Unless you know somebody personally who knows how to rebuild a transmission you're better off finding a good used one.
I found a nice manual for $350, an auto shouldn't be much more. Between the FS threads on here and the local salvage yards you should be able to come up with one. I wouldn't look at a U-pick-it kind of salvage yard for a transmission but you can search the inventories of the local places online.
But I'd look for it yourself, don't let the guys at the shop find it for you or they are gonna mark it up more. And if you can find somebody that knows what they are doing it's only about 4 hours of work to put it in.
