4L60E jumps/shifts hard

[davbell22602]

1997 Chevy K1500 Automatic 4L60E 126,*** miles currently

I notice my trany shifts hard when changing gears. I heard that 4L60E is not very strong. How do I make it stronger so it dont shift hard? What years of tranys will interchange with mine?

1996-1999(obs) 4l60es will fit right in your truck, the 95 had a 1 piece trans, the 96 is when the 2 piece came out., something about a shaft that doesn't work, Im still doing my research.

Wayne (swaggerwagon) can tell you exactly what you need to know.

Do i have the one or two piece bellhousing? I found a 4l60E core w/ 2 piece bellhousing otu of a 97 gmc k1500.

Sounds like the trans is on it's way out...hard shifting is usually a sign of impending failure...you need the later model 2 piece unit...the one you found is a direct replacement...

Its only noticeable on 1-2 and few to none on 2-3 shifts. What about the accumlator spring being bad? How kinda of trans kit do I need to fix the stock problems that the 4L60E had? What about a shift kit? Does the computer need reprogramed for a shift kit? I was told the trans shifts electronically.

You need to get it hooked up to a Tech II scanner, to see if your shift solenoids are working correctly.

TPS could be bad

Wouldn't I get a engine light if the TPS is bad? I have no engine light.

Whats TPS spec supposed to be when checking with a multimeter? Will a bad TPS cause a ignition miss also?
