when rolling down the road if i put my trany in drive and let off the gas it drops to idle and when i step in the gas it takes a sec to get toe the proper rpms to accelerrate what should i do??? is there a ajustment i can mess with to get it right i got 4.10 gears in the rear if that helps any

 

one question, how the auto with the 4.10s ??? whats the revs at 70 mph ??

does the car actually drop out of gear?? I presume the ecu has been tuned to the gears ? Sometimes mine kinda does it when its in between gears sort of thing. Is it like say your driving at 50 mph or something then let off and the revs drop to idle??? then do you step on the gas hard or just gently??

does your tranny hold gears?? if i put mine in 1st it will hold from a stand still to the limiter and not change until i put it in 2nd. Also can you gear down ok, i can put mine in 3rd and drive about and as soon as i put it to 2nd it gears down. Mine is a stock box

 

1-2 acum spring broke? easy check ... drop pan unbolt the 3 bolts from it and check it out let me know if i can help ya man?

 

ok will take a look at the 1-2 acum spring also it is now sliping second it went back to working right when selecting the gears manualy i got another trany that i just rebuilt myself ahhh i hope it works right gona put it in on friday i got a tci steet fighter kit from summit and had a buddy looking over my sholder the trany that is in my car got from a friend for 100 $ so i will pull it out and overhaul it if the other one works it was my first trany i ever tore into the kit came with a shift improver and clutches seal i also replaced a piston . yes car was tuned for the gears so thats ok just tring to get to the track and see what it will do

 

sory forgot to tell you that the rpms at 70 are 2900

 

Keep us posted if and when you find what it's doing. The trans in my 92 Vette is doing the same thing. If cruising down the road in any gear but O/D, the rpm's drop to idle when I let off the gas. I can feel it coasting free, no grab. Then give it gas and the rpm's go up until it grabs again. I also get a good 3-4 second lag between reverse and when drive finally grabs. And after a drive, the trans makes a strange whiny noise after it's put in park (not a gear type whine). Put it in reverse, then park and the noise goes away. The trans shifts good and crisp under power, with no slips though. Does any of this other stuff sound familiar too? As near as I can determine, I think it's the torque converter. One reason is because in O/D the converter is locked together, and that's when it doesn't act like it's going into neutral. I think I may have to eventually replace it, maybe with a higher stall (darn)!

 

nothing is broken just needs rebuilt the one i rebuilt i have 123 but no 4 have to rip it out and check 4 clutches talked to a trany guy he said as soon as i get it apart i can bring the drum to him he would set me up i guess 3 out of 4 ant to bad for the first time sure would have been nice to get it right the first timebut o well i'll get it right gonna out long tube headers and y pipe on soon plus egr block off too and than take it to the track and see what i got the master rebuild kit from tci is one hell of a kit it comes with the shift improver and you have to drill out the holes in the valve body but i sure shifts im gona rebuild the other trany too not sure on what size stall converter i should get any answers ? hit me back later

 

According to the FSM lack of engine braking in 1-2-3 could be due to:

Shift linkage out of adjustment

Valve body problems
4-3 sequence valve stuck
checkball out of position
spacer plate and gasket damaged or out of position

Input cluch assembly
turbine shaft oil passage plugged
turbine shaft seals or ***** worn, damaged, missing
porous forward or overrun piston
bad overrun piston seals
overrun piston checkball not sealing

 

well mine is doing this also. and it likes to stay in 3rd gear to. same reason???
