Riviera T Type Transmission


Recommended Posts

Hi all, looking for an '82-'84 Riv T Type trans with the 3.36 final drive-this is for an Eldorado I'm working on. Anyone parting a Turbo car of those years? Alternatively I would be interested in the final drive unit alone. The '82-'84 T Type and Eldorado for the high altitude market were the only cars equipped with this axle. A 1985 T Type will not have this part. 

 

Thanks!

 

Anthony

I have a '85 "T" type Riviera (V-6 Turbo) that I bought new in August of '85.  I checked the original build sheet and it shows code F57,  3:15 rear end ratio as standard.

Dave, the brochures and parts manual all call out a 3.15 axle for the 85 Turbo Riviera. I have another thread running for this part on the Turbo Buick forum as well, and someone with an '85 Turbo convertible messaged me back that his car has a 3.36, and sent a picture of his build sheet showing it. Very strange, maybe a convertible-specific thing? or perhaps an early model year build.

  Finally getting around to researching this..apparently, on V6 turbo cars the 3:15 was the standard axle and the 3:36 was optional. Pics are from the specs in the `85 dealer album and Riviera wholesale Car Order Form...enjoy...
