Hi, I'm new to this list so have mercy...
Have a 86 deluxe 4x4, have done a complete rebuild (my first) soft kit, plates, bushings. I only have 100psi pressure in the forward gears. Reverse has 275psi when stalled. It shifts fine from 1st to 2nd, but wont up to 3rd. If the OD switch is on it freewheels in OD. All the volts read okay from the ECT as it is trying to upshift and it locks up just fine. Reverse works fine. Transfer operation is fine. Delay time from N to D and then from N to R is near zero, which would indicate the forward and direct clutches are okay. Ive been told that I have an open hydraulic circuit from the main trans to the transfer and that is keeping 3rd and OD from engaging. Anyone seen this before? Does anyone have a hydraulic circuit diagram for the trans and transfer as a whole?. The factory manuals I have only show them as separate units. Thanks for any help.

 

Come on, there's got to be someone out there that can give help on were I should look for a pressure leak between the trans and transfer.

thanks
