Tranny hesitation and shifting hard

Did you check the ATF level like it was motor oil, or according to the directions (= engine warm, running, idle, tranny in Park)? Could be it needs the bands adjusted, or it may have a pump going out..if fluid level is correct when checked under the right conditions, have it checked out by a tranny shop

Yup - I checked it correctly. I will probably take it in, but hate to throw money at a truck this age.

That doesn't sound good. How much could I expect to repair it, if this is indeed what has happened?

take it to a shop that does a lot of GM trucks

tell them you want the Sonnax 'Sure Cure ' kit put in the valve body

price will vary, I'd charge 475, refundable toward a full rebuild if it didn't fix the problem, or if the unit needed a full rebuild within a year

Ya but your a stand up guy. Shouldn't he ask them to diagnose it? If he goes in and tells them what to do, shouldn't he expect $475+ and a big ol' F*ck You if'n it don't fix it?

I had a 98 3500 dually that had a hard shift and hesitation.... believe it or not it was some kind of a fuse. That's it.....

Have a Great One ! Bob :)

you know, we need a FAQ around here

the problem is that the bore in the valve body for the 'torque converter regulator control' valve has worn

oil leaks past the valve instead of applying the converter clutch in the converter

the ECM sees the slip, and jacks up pressures to compensate

if you scan it, you will have a code P-1870, 'Transmission Component Slipping'

at your mileage, it's a toss-up whether to fix only the problem or to do a complete overhaul plus fix

thanks for the reply Time to go to autozone and pull the codes I already know we have a prob with an O2 sensor or two.
