Angelo Voltura Posted May 18, 2020 Share Posted May 18, 2020 Any of you guys tranny gurus? My c6 is fairly fresh but I'm looking to upgrade if possible. Currently I have a pink band modulator, S code servo, b&m street strip shift kit, not sure what code lever, B&m deep pan and a remanufactured Ford stock stall converter. Was thinking about an R code servo and a new converter at 2000 stall. Any suggestions? I'm not a tranny guy at all so this is new to me. Link to comment Share on other sites More sharing options...
85lebaront2 Posted May 19, 2020 Share Posted May 19, 2020 Angelo, I would get ahold of an ATRA manual and possibly parts list. ATRA probably has some drawings and specs on the C6 servo. I never needed to upgrade my C6, the C4 in my 1964 Falcon was another story. For that one I ended up using a front band and servo for a 300 (yes they put them behind those torque monsters). I had started with a Hi-Po 289 setup, and modified the servo cover so the back side of the release area became the apply. When I was able to source a servo and cover for a 300 I used that as it was almost the same as what I built. The C6 has a relay lever, I do not know if there are different ratios for them, I do know that there used to be a case girdle for the C6 to keep the case from spreading under hard shifts. If you can find someone who drag races a C6, they can at least steer you in the right direction. Good luck with it! Link to comment Share on other sites More sharing options...

Yes the C6 levers have different ratios which is why matching is important. I think I will probably be ok since the spring was changed on my S code servo. My dads truck was originally a 300 with a C6. Mine shifts nice and firm but I figured while it was out it couldnt hurt. Thank you! Link to comment Share on other sites More sharing options...
