HiCustomer Thank you for asking your question on JustAnswer.
Did you use the guage block while setting the pressure?
What is the tv pressure at idle with out the block installed?
Do you have the means to check line pressure also?
I have no gauge block....I just used a gauge
I adjusted the tv pressure by the description in the manual by setting
It at 35 lbs. at idle.
No, I don't have the means to check the pressure line.
Why do I have forward movement in reverse and neutral positions
as well as in the forward selection position?
I was getting to that, just wanted to be sure you had the tv set correctly. A guage block must be installed when setting the tv to 35 psi.With the block out tv should be near zero at idle. I don't think the tv is your engagement problem.If the trans has been sitting a year and never used then something was probably assembled wrong during the rebuild.The valve body can't apply forward and reverse at the same time unless the wrong sep plate gaskets were used.Without seeing the trans disassembled it is hard for me to say,If you have to rev it to 2800 to get it to engage and then it engages fwd and rev at the same time there is definitely something besides tv pressure causing it.forward or rev clutch stacked to tight,one way clutches installed backwards,stator support seal rings mis installed,broken or missing......I would try to set the tv correctly then reevaluate...Sounds like you have the tv too high if you set it to 35 on the hard stop then its actually more like 70.That is probably causing the whining/buzzing the pump is at full line pressure especially if you are in the throttle then tv is closer to 100.This could cause crossbleed on the stator support seals,line pressure would be 300 psi plus at that point.

This revised method of setting TV linkage on all AOD transmissions is the only way to adjust the linkage to the middle of the specification curve. This method sets the linkage to the most sensitive point.
The new procedure attached uses a TV control pressure gage block service tool D84P-70332-A. If that tool is not available, alternates are listed in the procedure. Highlights of the new procedure include setting the TV linkage at idle with the gage block installed to 35 +/- 5 Psi.
The "TV pressure method for adjusting the TV linkage" procedure is recommended for transmission shift concerns while the "Linkage Adjusted at the Carburetor" procedure is recommended when the idle speed is changed by 50 RPM.

The following procedure may be used to check and/or adjust the throttle valve (TV) rod linkage using the TV control pressure.
Thank you for your reply. Unless I purchase a gauge block, I
do not have access to one. I will look at your alternative suggestion.
What is your opinion of installing a shift kit in the stock valve body?
What about purchasing TCI's constant pressure valve body? Would
There were alternatives in the procedure for guage blocks.You can fabricate one using the measurements provided or by using the size drill bit that was referenced in the procedure.
I think a mild / moderate shift kit would be ok, but if they did not beef up the trans at all during the overhaul then I would not increase pressures too much because the factory parts will not handle the increased pressures.If you do get a kit a would recommend one from baumann.They are the best and all I use.The kit lets you decide how much firmness to add to the shifts and effectively addresses the O/D servo pressure apply that plagued these transmissions for years. I do not think a kit will help your current problem. I would get the TV pressure under control and if that fixes all of your concerns then think about the shift kit.
If I understand you right, you do not recommend increasing the pressure
on the rebuilt transmission by putting in a shift kit. Are you familiar at all
with TCI's Constant Pressure Valve Body. By the description, all you have
to be concerned about is setting the tv pressure and you are good to go. Maybe
Baumann has somewhat the same thing. Thanks, Kenny
