Is there anywhere on the internet that tells which transmissions were used in which vehicles in specific years? For instance, I want to know what the 1970's chevy pickups used for 4 speed trannys. Also, I have a 1974 Ford pickup with 4 speed, I read in one place that most all fords used T18's but I think maybe mine is a NP435. I don't have any paperwork on my ford. I want a web site that tells me this info. I know Off-Road.com has a lot of tranny info but I want more. Thanks.
