The RS series of transmissions are Borg Warner units, modified by Keisler (only the 68-70 B body applications are out), very much the same way they mod the Tremecs, Keisler still offers Tremec TKO for Vettes....I did a 55 Chevy with a Keisler TKO600 5 spd last year or so, no issues, if your going to convert a Vette to 5spd, go with the TKO 600 5spd either Keisler, or American Powertrain, Hurst also has a TKO 500/600 5spd kit (Summit Racing)

what borg warner tranny is it based off of? AFAIK B-W divested it's tranny production and sold it off to TTC (Tremec) in the late 90's....







Borg warner T-45 5 spd .67 OD IIRC........just go to Keisler's site, info is right there explaining what mods are performed and what parts are upgraded
