Will GM 200r4 work with factory floor shift location?

Sorry, it took a while to get you the part #'s, but I didn't have internet at the house on my time off for Christmas.

If you don't want it to shift hard, don't buy the bigger pressure valve. It will still shift firm and don't use the better servos. Use the factory Grand National servos and it won't shift extra hard but firm.

The part#'s in the pictures are just what I had in stock, so they are not the ones you need, but I thought I'd post anyway incase others wanted a hard shift. They are sonnex, I usually run fairbanks servos, but they look like the same quality. They may actually be made by the same manufacture…who knows.


I really appreciate you following through. It's no big deal that you took a while with Christmas and the holidays everyone's been so busy including me. I'm still prepping the tranny and trying to find which parts are best for my application. I tried to "THANK YOU" on your post but I couldn't figure out how to do it. I even looked in the FAQ area and no help. Anyway, you answered the EXACT question I needed an answer for on how to get a firm shift without that harsh "BANG". My little girl will drive this car in a couple of years so that's really important...so thanks again. If I can figure out how to thank you on FABO I'll do it!!!


My 2004R list so far includes:

Superior super servo (not sure which one this is)???
Furnace brazed converter (don't know if I need the turbine and fins brazed, makes a difference in cost)
