We can hear it apply, but not positively. He showed me where to air test that clutch and it has alot of leakage. It up shifts very early, we found what looks like a diesel governor, will work on that next.Īs for engine breaking in low gear. I now believe we are compensating for a worn band. We still have some movement on the cover and I will try welding more and 1 more large shim.
We assume the 2nd servo piston was bottoming out or binding the spring. kit.Īfter adding all of this to the servo we have 2nd gear, somewhat weak, but the band is applying. We welded a strong 1/8" on the end of the servo pin and installed 2 of the large diameter shims under the servo cover as in the Jr. We removed a couple small shims from the servo pin and reinstalled the snap ring which was eliminated by the -2 Transgo kit. ( I bribed him with a few beers and some popular dead presidents) and I have a hoist in my garage. I actually brought home a transmission shop owner to go over my problem. Transgo offered some help, but I'm not exactly their customer so the calls are rather short and sweet.Īny ideas? Where do I go upstream from the servo to look for a problem.
700R4 SHIFT KIT TRANSGO FREE
Now it free wheels in low and 2nd when puilled down manually. Stab the gas under 25 mph dumps it into 1st where it stays 'till throttle is reduced.
It will hold low gear 'till I back off the gas (over 6k rpm) then it hits 3rd gear. I also added a corvette servo and reshimmed per kit instructions to just under 1/8" at the cover. I cleaned up the plugs installed in the seperator plate and reassembled. I ended up with 1 ball left over.don't know where it was. Transgo faxed me the instructions and i reviewed the installation. What I found was the trans already has a transgo 700-2 kit installed.
700R4 SHIFT KIT TRANSGO INSTALL
My plan was to drop the pan to confirm TV adjustment and install a transgo junior kit to further tune the tv circuit. I was also concerned about the TV adjustment as it has a TPI with Lokar cable, and as I said, was setup by someone else. Shifting was lazy and it "free wheels" when I down shift to low gear, but pulls strong when I get on the gas. I have an early 700r4 behind a ZZ4 350 in a '67 C-10 pickup.
