I have the B&M shift kit in my 86 GN thats a daily driver and it works just fine. and it came with eveything i needed.įor what its worth. Now back to the rebuild kits! What do I need to do a good rebuild? I see a 'Master' rebuild kit on eBay (auction number 320066328976). Does the B&M shift kit give me firm 1-2 & 2-3 shifts but not too much?Ĭan the B&M kit plus the servo upgrade give me what I am looking for? I think I said somewhere that I had the 200-4R in my '87 MC redone by a shop and they did a very nice job, but the 1-2 shifts were just a little more firm than I would have liked for everyday driving.Īlso sounds like I want to the servo upgrade, but want to understand if the servo in the GN trans is better than the servo in the Cutlass (Ed39?)? I don't want it to be annoying under normal driving, just firmer shifts than stock for both 1-2 & 2-3 shifts. My motor is basically stock (other than the basic fuel pressure regulator and adjustable waste gate) and I will NOT be racing this at all! Sounds like the Transgo will be a firmer 1-2 gear shift than I want. Okay, thanks for all the opinions! Not sure if I am more confused :shock: or have more info than I need. He'd done it on PGs and 400s, but obviously something wasn't right with the 2004R version. Needless to say, that was the end of that.īTW, this was with a very good race trans builder who was doing a 'fresh up' for me and was highly recommending this kit. it ruined my valve body (involved drilling new holes in the VALVE BODY).Īfter several fruitless attempts on the phone with Younger (who actually was very supportive, even if we couldn't get it to work), I ended up with a fully manual VB that slipped in 3rd gear. I think the TransGo super race kit was the one that really soured my opinion though. Their basic kit is OK (but I didn't notice any significant improvement, other than it really BANGED 1-2 gear with the stock converter). I've done Superior, B&M, Fairbanks, TransGo, TCI kits. Guess what the Superior is very similar to? :shiny:Īlmost all the same components and the same basic mods to the separator plate.
