l67ss Posted October 10, 2014 Report Posted October 10, 2014 what is the final drive ratio of the trans in an l36 equipped 99 bonneville? thanks Quote
Imp558 Posted October 10, 2014 Report Posted October 10, 2014 It's all about the tag on the back, need the 4 character code off it. Don't clean the grease off the tag with solvent, the information is painted on, lol. http://www.gmtuners.com/transmission/1999_4T65-E.pdf Quote
White93z34 Posted October 12, 2014 Report Posted October 12, 2014 Could be 3.06 as well but I'm not sure if they were doing that after 97' Quote
Turbocharged400sbc Posted October 12, 2014 Report Posted October 12, 2014 3.05 FDR for the NA cars was post 03/04 and thats the diff, so you can swap in a 3.29 NA or and HD diff and get the 3.29 FDR the 3.05 FDR on the NA cars is what allowed GM to get the 04+ ULEV certified Quote
Turbocharged400sbc Posted October 12, 2014 Report Posted October 12, 2014 i dont think any of the 96/97+ 65e's had the 3.05 fdr? i think that was from the 60e HD's? Quote
l67ss Posted October 12, 2014 Author Report Posted October 12, 2014 im hoping for 3.29s....... lost oil pressure on my l67 the other nite resulting in a lunched shortblock. did some labor swapping for an l36 and trans from a totalled bonneville. have a pcm from a 98 z34 programmed for 3.29s. guess ill be running na for a while.....
