and i have noticed when in drive with its gear hunting sometimes if i need more speed and i just slowed down it shifts into gear harsh and i can hear a metal clunk sound.Įdit: Also forgot to say that i get a thump on 2-1 downshift when braking harder than normal usually 3rd gives it a bit more consistent firm shifts and drive gives sometimes soft and sometimes a bit slower hard shifts. The shifts can be changed even thought, every start up the shifts are different, sometimes a hard shift sometimes smooth shifts sometimes it feels like a good shift kit, it depends on the pedal (never wot) at light throttle it shifts good and after a while it will shift as if light throttle but when giving moderate throttle, if just moderate its a bit more of a bump, if i drive aggressive it can hit hard sometimes or drive perfect with good firm shifts, i usually drive in 3rd because im in nyc and in drive it can hunt for gears sometimes when i coast and then have to give gas which can be frequent. It was a pain in the ass but i got it in and the first drive felt good but then it went back to bad shifting, the shifts at this point are the best so far, the delay isnt much and the shift isnt all that harsh but still is a hard shift (just so you understand the scale of how im rating harshness when it shifts you feel it in the car as a bump and it dosent feel firm and progressive)
4L60E SHIFT KIT INSTALLED NOW SLIPPING INSTALL
Now we get to where i install the servo - about another 2k miles later (and how it sits now) also idk if it means anything or my app was wrong but once when i went into first and it shuddered i noticed the scanner said it was in 2nd gear, at another light i did it again and it said 1rst gear and that time it worked fine. this happens almost all the time but sometimes not, when it dosent it drives fine and the shift from 1-2 is the same as in drive.
4L60E SHIFT KIT INSTALLED NOW SLIPPING MANUAL
also lock up was like going in a gear and felt very good.Īlso this is the point where i first noticed another problem, im not shure if it was there already but when i put it in manual first it dosent roll, and if i give it gas the whole car will shudder. All other gears were good and it felt like it had a shift kit and was working good except for that one gear. but what did change was a very harsh 1-2 shift almost always no matter what unless i was feathering the throttle. we then installed everything and it had a better shift time with not as much delay but sometimes almost the same as before. both the gaskets and plate were worn and there were signs of leaks from the gaskets. We dropped the pan and saved the fluid, cleaned the somewhat dirty magnet and removed the valve body and accumulator pistons (they were not stuck in bore, and they seemed to not have any wear on the pin bore and the seals were good) there were about 3 checkballs stuck in the plate. separator plate & gaskets, pinless accumulator pistons,nylon screens and I also got new torlon check balls) Now we move onto the shift kit install about 2k miles later: ctpowertrain kit (transgo shift kit, corvette servo, and new v.b. And that did nothing at all to help the shifts the pan magnet was pretty dirty, the fluid was dark and bad smelling but not much burnt smelling just old. the rest of the gears were fine.īecause of this we decided to do a flush by connecting the output to a hose a letting the car run no chemicals used, we also did a filter change and replaced both shift solenoids (thinking it may help). The 1-2 shift was very delayed and harsh, it felt like it was slipping bad also i could never let go of the gas or give less gas during the shift to help since it would just hang between shifts and when it did engage it was very harsh. Starting from when i bought the car at 133k the dealer replaced the trans fluid OK now to explain the problem (also the dipstick never wiped clean it always has a black stain with it on the napkin) Ok well there is alot to say so ill try to break it into sectionsĪs far as I can tell the trans is original (no markings on valve body)

OK well this is my first post and yes I did search but it's hard to search for this problem specifically.
