smokuspollutus Posted June 9, 2019 Share Posted June 9, 2019 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!

1965rivgs Posted June 9, 2019 Share Posted June 9, 2019 Hi Anthony, Just curious about the `85 exclusion...did the `85 have a different final gear ratio? Tom Mooney Link to comment Share on other sites More sharing options...
smokuspollutus Posted June 9, 2019 Author Share Posted June 9, 2019 Hi Tom, the '85 switched to the 3.15 ratio found on all 4100 Eldorados. Not sure why, maybe cost savings? Link to comment Share on other sites More sharing options...
1965rivgs Posted June 9, 2019 Share Posted June 9, 2019 Hi Anthony, Very interesting...may I ask what the source of your info is? Factory lit, personal experience, etc..? I`d like to do some research on this, Thanks, Tom Mooney Link to comment Share on other sites More sharing options...
smokuspollutus Posted June 9, 2019 Author Share Posted June 9, 2019 Tom, the parts manual covering these years calls out the 3.36 for '82-'84, and the 3.15 for '85. Some further online researching confirmed this. Link to comment Share on other sites More sharing options...

smokuspollutus Posted April 19, 2020 Author Share Posted April 19, 2020 Still looking, and as an update it seems as though some '85 T-Types may have also had the 3.36 axle. Interested to hear if anyone has anything. Thanks Link to comment Share on other sites More sharing options...
DAVES_BUICKS Posted April 20, 2020 Share Posted April 20, 2020 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. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

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... Tom Mooney 3 Link to comment Share on other sites More sharing options...

RivNut Posted August 9, 2020 Share Posted August 9, 2020 Am I reading these correctly? The ( ) seem to show a consistency between 3.36 and California. Link to comment Share on other sites More sharing options...
