200 4r 1st to 2nd shift

I just put a 200 4r to my 327 sbc. The transmission was supposed to been recently rebuilt.
The problem I am having is it is very sluggish shifting from 1st to 2nd, if it shifts at all. If I step down on the gas it slips.
I installed the TCI lock up kit. ( I wouldn't think this would have anything to do with the problem)
I have adjusted th TV cable many times. I just dropped the pan to see if the plunger was fully depressed. It lacked a 1/4" of having the plunger flush with the bushing. I adj. the cable so the plunger would be flush. When I did this, the plunger is pushed in Bout 1/4" at idle. Is this OK?
I have also checked the pressures at the test port. I have 50lbs. at idle and about 120lbs. at WOT. What kind of pressure should I be seeing?
I have read just about every post there is pertaining to the 200 4r.

I have not tested the car since I dropped the pan and visual check the tv adj.
Is there anything else I should check while I have the pan off?

Any help would be greatly appreciated.

Hmm, those pressures are way low. Maybe "Crosley" will pipe up...

Pressures are way too low as stated. Need to check the pressure regulator valve train to be sure it is properly installed. It may not be all the way seated.

Any pump cavitation noise?

Be sure the filter is properly installed (not two seals, not cracked, not plugged) while in there.

Thank You, for the responces.

There is no abnormal noises.

What are normal pressures?

I am looking at a valve body breakdown, but I am not sure which is the pressure regulator valve. Does it have another name?

I forgot to state in the origional thread that the tranny shifted OK when manual shifted through the gears.

HELP! I would like to get some more info if anyone could make some more suggestions. I would like to know what amount of pressures I should be looking for. And is ok to have the TV Valve pushed in about 1/4" at idle. This is where it is when I adj. the cable so the valve surface is flush with the bushing at WOT.

Thanks in advance for ant feed back.

the pressure regular / boost valves are in the main pump body.

If the TV is too tight the 200-4r may not down shift back to 1st gear at a stop

Pressure Regulator & Boost Valves

Pressure Regulator & TV,Low/Reverse Boost Valves are in the left side hole in bottom of pump cover in these Pics. When you drop the pan the pumps at the front with the TCC Solenoid in center with wires connected.
