What about doing all of the air pressure checks with the rubber tipped air nozzle. From what I gathered you did do that for the servos & are there any other air checks that can be done? Otherwise it looks like it has to come back out

There is pressure at the front and rear servos but how much pressure?

Even with broken drive tangs a pump can put out some pressure but not much.

I agree you need to know how much the fluid pressure is. What about manual low ? Will it move at all in manual low ? Ron

If you are sure there are no issues in the overdrive section (e.g. problem with the direct clutch) then it's likely at the input end. Possibly a problem with the input spline on the new converter or an issue with the input shaft itself.

Torque convertor? Just because it is new, does not mean it was built correctly. That is basically all that is left.

4X4 TRANS
I WAS THINKING CONVERTER ALSO
TOOK THE OD ASSEMBLY OFF TO DOUBLE CHECK IT.EVERYTHING IS OK
WHEN I REMOVED THE VALVE BODY I ONLY GOT A PINT OF FLUID DRAINING FROM TRANS. I DONT BELIEVE THE CONVERTER IS FILLING UP ON FLUID.IPUT 13 QUARTS IN AND SHOW FULL.

I'm thinking exactly as you on the direct clutch in the OD unit possibility. No direct clutch means no go....If he's got servo pressure then the pump must be doing something.

I know this is not your problem, but I remember of a fellow changed who the tranny in his 4X4 some years ago. It was in the garage sitting on level ground and would not move. He about went crazy. He called and told me what was going on with it. When he said it "raked gears" going into park, I knew what it was. Simple fix. He had his transfer case in neutral.

Did you disassemble the VB? If so, did you get the selector lever back on the valve?


OOPS!!

I guess you did. If not, you wouldn't have pressure at the servos.

Perhaps a sprag failure allowing the guts to spin? Maybe dropped the link on the bands?

I thought about the direct clutch but I dont believe it will cause his problem because there is an overrunning clutch in the overdrive unit that holds if the direct clutch slips. It is there so you dont get and rpm flare on the 3rd to overdrive shift when the direct clutch lets go and overdrive clutch comes in.
I had a problem once where the 518 trans would slip in reverse but not drive and it had just been rebuilt by one of our techs. I found out he left a disc out of the direct clutch but it did not slip in drive just reverse because the overrunning clutch held in drive and in reverse it does not hold of course as the power goes thru just the direct clutch. It so happened this trans had updated parts and called for one more clutch disc but the tech did not count how many disc he took out and put back what the manual said as the update was a TSB.
