I installed a B&M transpak into my '66 "green dot" C-4. The kit I bought is specifically for a 64-66 C-4. I'm sure thats the tranny type and year that I have. I used the medium, or street/strip, firmness option. It shifts fine by itself. My problem is when I try to shift "manually". If I start with the shift lever all the way back and shift from first to second, no problem. Once it is in second and I manually move the shift lever back down to hold second for a while, it will shift back into first! Prior to the transpak install I could shift from 1-2 back down to first position to hold second for a while, then move the lever forward one position to get the car into third. Did I install the kit wrong, or is this just the way it goes with a 64-66 green dot tranny?------------------ Thanks, John '66 coupe, 289, c-4,3:20 open rear,headers, holley 4160, duraspark ignition.

Sounds like it is working fine. I have the same in mine, but I use the B&M ripper shifter as well. First puts me in first gear, second in second, and drive in third - or automatic.

I've only driven it twice since the installation of the kit. The shifting is harsh and does take some getting used to. It definately eliminates the "lag time" between shifts. It will be quicker in the 1/4 mile because it upshifts faster. It seems like it will beat on the U-joints. I might install a drive shaft loop in case the front U-joint goes. It will chirp second no problem, and chirp third if I try to. The kit cost $50 and was fairly easy to install.There wasn't many options to choose from for this tranny.

If I remember right, the "Green Dot" or early C4 trans doesnt operate the same as 67 and later C4 tranny's. The drive select range is Low(1), Drive(1-2-3), and Second-Third(2-3). If you put the early C4 in the "normal" drive position, you will start out in 2nd gear. I didn't realize that you could manually hold the green dot trans in second. That's interesting to know. Now as I recall, you can swap valve bodies between the two trans and have a regular shift pattern in an early C4.

My shifts are really harsh, enough to the point where I'll hit my traction bars on the leaf springs. I have traction bars without the rubber ends so when they smack it can be easily heard inside the car even over the exhaust. The ripper shifter doesn't do anything different for the shifting, it just provides me with a neutral lockout and precise gear selection. I recently picked up the button knob for it which I have rigged into my 2-step rev. Don't have the T-brake yet - still using the foot brake, but its still nice to be able to select my launch rpm. I'm using the MSD Digital-6 btw.
