I just installed my ftvb a few minutes ago. I then proceeded to drive it around the block. And, I'm having some serious problems. First off, overdrive is non-existent, the truck doesnt seem to want to shift at all, and every now and then it seems as though something in the drivetrain is spinning and not catching.

What caused this? I have a feeling it is something simple, as nothing went wrong during the install. Maybe too much fluid, not enough torque on the vb bolts (which i double checked), bad gasket, defective vb? What do you guys think?

 

did you fill it back up with fluid? if so, then maybe a bad VB... where did you get it from?

 

Yeah i filled it back up with fluid. I bought it from Mike at MAD enterprises

 

there is a plug on the tranny close to where you ahve to work, maybe you disconnected it or something?

 

i would contact mike. Greg Evans (FT) always stands behind his products.

 

Nope. I just checked and everything is plugged in

 

The overdrive light is not blinking and does work properly, but when overdrive is turned off, nothing happens.

 

Just got off the phone with mike. Im sending the vb back and getting the new plate kit instead. Thanks for your help

 

Took the vb off, put the stock one back in. Everything is fine now, was a defective vb. But the 1-2 shift is still a little hard...maybe i left the other springs in...no big deal though

 

As long as the weather holds I'll be there.
