l67ss Posted August 21, 2013 Report Share Posted August 21, 2013 Wondering if a 4t65e from a 99 olds intrigue 3.5 will interchange with a 98 monte z34 4t65e 3.8 Quote Link to comment Share on other sites More sharing options...
RZB1992 Posted August 22, 2013 Report Share Posted August 22, 2013 Not positive if they will interchange or not, but I do know that the 1999 model year Intrigues with the 3.5 had two different transmissions - one with a 3.05 ratio (RPO Code F83), and one with a 3.29 gear ratio (RPO Code FR9). Make sure you know which you're getting when you get one. Quote Link to comment Share on other sites More sharing options...
RobertISaar Posted August 22, 2013 Report Share Posted August 22, 2013 it will all bolt up no problem, same bellhousing pattern between them. working 100% as intended.... maybe. with the 3.29 version, pretty good chance of it being acceptable, to say the least, especially without any calibration tweaking.
