    I just had my tranny rebuilt and I was wondering what a B & M shift kit could do for me. The blazer I am helping sell for a friend has one and even with a 305 it drives like a dream. My rebuilt tranny will through you back in the seat if you develope lead foot syndrome [​IMG], but I have heard only good things about B & M. Any input would help alot!

    B&M kits are a good all around kit, but for the ultimate in performance, TransGo is the way to go. All things considered, B&M kits are a worthwhile add-on, particularly because I'm sure that you don't want to drop your tranny again to add the TransGo.

    I would go with the TransGo. I have used both. The TG is much more user friendly than the B&M. The TG even comes with an install video.

    If the tranny shifts hard what was done to it? The question is whether it is binding? That can feel like a hard shift. Personally everything I have gotten from B&M has been junk... well if not junk, not as nice as other stuff on the market. I would go w/ Trans Go or a Gil Younder (sp?) kit. Also if it is a 700R4 don't do a shift kit, but I'll assume it is a 79 w/ a TH350. It helps to fill out the profile.

    You have to pull the tranny to add a trans go shift kit to a turbo 350? I have recently had my tranny rebuilt, and after a breakin period i will be adding a shift kit. Not sure whick kit i will use, but definately don't want to pull tranny!

    thanks

    TransGo, TCI and one other that I don't remember the name of use upgraded clutch packs, and several other parts that require having the tranny out of the vehicle to install - I believe that B&M is the only valve body only kit on the market.

    Well I have posted some really specfic posts on the 700R4 and how to modify them, but you can look back for those if you are interested. But basically 1:strength of tranny and 2:a good shop w/ 700's can modify it to shift just like a shift kit w/out the costs... approx. $20 in parts and about an hour worth of labor.

    The strength issues come down to the sungear shell and the sprag... they are very weak and hrad shifting will eventually lead to breakage. Plus another thing about these kits is some idiot decided to put Vette servos in for a hrad shift. Well the vette valve bodies all include aux. valve bodies and are specfically set up for the servo so it won't make an extremely hard shift. When they are thrown in a regular 700 then make the hard shift, but it is really hard and will reduse the life of the tranny and it definetly beats on the gear and sprag. Plus if I had a dollar everytime my buddy (He is a 700R4 guru and actually has one behind his street rod BBC... not to mention works in a tranny shop) had to rebuild a 700 that was rebuilt or had a shift kit installed about 10-20k back that was binding (which feels like a hard shift so is easily mistaken). That is what happened in my truck... I bought it and the tranny was about 20K old... well basically the 2-3 and 3-4 shifts were binding so bad it overheated (even w/ the cooler I added) and basically blew the pressure regulator and ton of other stuff into the pan. It was a mess. But this is my experience... plus I really don't think a shift kit is necassary or even desirable in a vehicle of this type, but again IMO.
