v8zed Posted June 11, 2002 Share Posted June 11, 2002 Hey Grumpy , I have a chevy trans that was made by New Process in the late 70s. It has a 3.09/1 1.62/1 1/1 and .73 to one as the ratio in a four speed box. My trans has a noise in second gear and when I call a Chevy dealer they ask what car it came from. Since I bought it at a swap meet I am at a loss as to it's original use. Do you know of a web site that would show options like this and what models they were available in ? Thanks, Dennis AKA V8ZED Quote Link to comment Share on other sites More sharing options...
Guest super280z Posted June 11, 2002 Share Posted June 11, 2002 sounds alot like a saginaw. these were common equpment in 70's camaro's and t/a's luckily there is an abundance of parts for them and they are about the easiest transmission to repair on the face of the earth. match the numbers to a specific car and you've got a parts source. ;D Quote Link to comment Share on other sites More sharing options...
v8zed Posted June 11, 2002 Author Share Posted June 11, 2002 Thanks for the reply, I needed to be more clear in my description. This is an Overdrive trans built by New Process (MOPAR ) with a chevy bolt pattern and input and output shafts. To order internal parts the dealer needs to have a model of car that it could have been used in. They have tried to look it up under tranmissions, but thier books don't list that way.

Mike C Posted June 11, 2002 Share Posted June 11, 2002 I would contact somebody like National Drivetrain for parts. They should be able to help you ID the trans as well. The only OD 4 speeds I am familiar with are the saginaws as well. They flip the 3/4 shift lever so that 3rd gear is really 1:1 and then put an overdrive ratio where 3rd used to be. It's usually fairly easy to ID parts from a 3rd party supplier since they coded them well because they sold to so many different manufacturers.

Mike kZ Posted June 11, 2002 Share Posted June 11, 2002 If it's built by Mopar, and has Chevy components, it could be an AMC tranny. I think AMC used a Chevy bolt pattern. Quote Link to comment Share on other sites More sharing options...
v8zed Posted June 14, 2002 Author Share Posted June 14, 2002 Hey Mike, Thanks for the National Drivetrain heads up. They know what trans I have and I am ordering the parts.Found this trans was used mostly in pick-ups and vans to help with gas milage. this trans is much stronger than the T-5 I had, and still has a .73 overdrive. Thanks Again, Dennis Quote Link to comment Share on other sites More sharing options...
Mike C Posted June 14, 2002 Share Posted June 14, 2002 No problem. Hope it works out well for you. Quote Link to comment Share on other sites More sharing options...
