Where can I find diagrams for a 1988 Ford F150 transmission? Thanks.

 

You will probably have to go on eBay and look for a FACTORY service manual. Maybe some of the tranny gurus have a better source?

DirtyDog?
Greg?

 

A local shop should have something for you.
An auto garage that use ALLDATA or Mitchell On Demand could help you out as well.
Which transmission do you have, there are a couple that could be in there. Do you need help on a specific part of it>??? Maybe I could help you there. -Mat-
