I just installed the Value Body and now the tranny slips, will not engage under 2000 rpm's. The fluid level is correct. I ran it through the gears upon restart, rechecked the level. went for a short drive and seems to shift fine, but slips under 2000 rpm's.
What did I forget?

 

Did you put the filter back in>??? -Mat-

 

Sounds to me like it's not torqued down properly. If the tranny is slipping, the only cause of that is not enough pressure to hold the clutch packs. The VB does not affect clutch holding, only the initial engagement firmness. Sounds like you are bleeding off fluid pressure and you need to spin the pump faster (higher rpms) to make enough pressure to engage the packs.

 

Also you are checking the fluid level when the truck is running correct>??? -Mat-

 

Yep, the filter is installed

 

Like Sal said....check the torque. Take it out and retorque it. Make sure the VB gasket did not get damged. -Mat-

 

I used a inch pound torque wrench, I double checked them. 85 inch pounds.

 

Reinstall your old accumulator body and see what happens....maybe you got a bad one>??? -Mat-

 

One problem I had (I think???) when I did mine was an air pocket got trapped and caused some odd things.

But yours sounds to me like there is a "bleed" happening. Is there possibily debris between the body/gasket/case? Maybe some dirt or a burr?

WOT

 

At least the new pan has a drain plug

 

I have been researching the FT Valve body and plan to buy one soon.
I read this related link on NLOC:

The customer said it was shifting hard not slipping. However maybe it needs a day or so, either way I would send Gregg and email or post in his forum on NLOC (use above link to get there).

Update, took it all apart and put it back toghter. Now it goes nowhere.
I'm going to reinstall the old one, now

 

 

WTH, I put it all back toghter with the original v/b and NOTHING
No go foward no go backwards, Me go nowhere It's so simple, what could go wrong?

 

How many Qrts did you put back in the trans? Didyou use Dextron 3? I heard it takes about 7 Qrts to refill. You have to check the fluid when the truck is at operating temp(hot) Make sure the V/B isnt sitting the wrong way I'm not sure ifit would line up but if it woul maybe you installed it 180 degress off. Lets us know
