hard shift into gear and from 1-2
i have a 96 awd s10 blazer with a 95 bravada transfer case i baught it with a bad tcase. ok so here is the deal i have no codes the valve body has been rebuilt with sonnax parts i have a new epc i have swaped the shift solinoids as well as the rest of the electronics but i still have a very violent 1-2 and when it shifts into forward and reverse is also hard i am running out of reasons for this kind of behavior any help would be greatly appreciated it is a 08/96 so it doesnt have the ground problem

If you figure it out PLEEEEEEEEEEEEASE let us know what it is. I have been dealing with this since i bought my Jimmy a year ago. So far i have changed the TPS, cleaned the MAF sensor twice, new EPC soleniod, new 1-2 acummulator and new Sonnax pinless forward accumulator piston and fluid and filter. Nothing has worked so far though im sure it has something to do with valve body.

Sounds like you are running full line pressure. That usually happens when you get an 1870 code which is caused by the TCC regulator valve bore being worn. They usually work right when cold but after they warm up then they lose oil and it throws the EPC to full line pressure. A good scanner should tell you where the trouble lies. Watch the EPC percent reading and see if it drops when you get on the gas. Should be at around 58 to 60 at idle.

I'd have to say it runs great besides the shifting, if anything maybe a little sluggish in first. Fluid levels right on, was just changed along with TPS, EPC solenoid and new foward and 1-2 accumulators and cleaned MAF.
