tranny problems

I bought a 77 Bronco with 33's a few months and the transmission (C4) slips when it makes the 2-3 upshift until the truck is warm. Before it's warm, the slippage is really bad (revs to almost 5 grand and then finally shifts) and then once it's warm, the slippage is slight if at all. I don't know much about automatics so would completely flushing out the tranny and replacing the filter fix this or do I need to bite the bullet and have the tranny rebuilt? Thanks for the help.

Re: tranny problems

Most of the time when they do that is becuse the seals are hard when it gets hot they get softer and dont leak internally but they need to be replaced to make it work right. also you dont say what gears you have if its3:50 you should change to 4;11 WITH 33" tires it is a lot easer on the trans and runs much better good luck Bill

Re: tranny problems

I haven't had a chance to find out what gears it has yet. As far as the seals go, where are they? Would I have to pull the tranny to replace them? Thanks for the help.

Yes that is the only to get to them basicaly you need to rebuld it and if you do install a shift kit will make it last longer and shift better and is worth the money good luck Bill

Re: tranny problems

It can also miss shifts from a lack of fluid - it could just be low, or the filter may be clogged. That's what I'd do first, and install a pan drain plug kit when you do it.

Re: tranny problems

The fluid's not low. I check that regularly (with my fingers crossed, etc...) but I think I will try changing the filter first... If that doesn't work then I guess it's time to let the pros take over [img]/wwwthreads_images/icons/crazy.gif[/img]
