I'm trying to solve a late shift problem in my 904 transmission that I installed a TF-2 kit into about two years ago.
I pulled the valve body and was checking some measurements and found that the line pressure adjusting nut was turned all the way out to 1 5/8".
My transmission book says the correct adjustment is 1 5/16" so I dont know if I made a mistake or what because I dont have the TF-2 instructions anymore.
Could someone tell me what the adjustment says in the TF-2 instructions?
I cannot find anything in the TF-2 kit that changes that adjustment from stock. The only change is to the PR valve. Your stock adjustment should be correct.

I really like TransGo products but their instruction sheets change from time to time for no reason. The link below is to a pdf file with early TF-2 instructions: http://www.mopar.ch.vu/bilder_public/TF2/TF2_old_instructions.pdfWith their blue spring installed in the pressure regulator, for street they tell you too adjust the spring plate all the way out until it contacts the retainer....for competition they tell you to do the same and then screw the spring plate towards the spring 6 full turns on the adjuster.

Is it the newer TF-2 kit that uses the shim and two springs on the regulator valve, or the older TF-2 kit with the single spring?
I think the newer kit has the adjuster backed off all the way for street or street/strip, and tightened up a bit for race. I will have to look through the garage to find the instruction manual?
You should have checked the governor pressure before dropping the valve body out. It could be the sealing rings on the output shaft or sticking governor weights. depending on the year, the filter in the governor may be clogged?
Same Issue - Different Kit
While were on the subject of late shifts - Can you explain further about the Governer Weights - Filter - Governer Pressure
I installed the [Email]B@M[/Email] Transpack many moons ago - As a matter of fact last week i just pulled the Valvebody to replace my Selector Shaft Seal , and i went through the Valvebody looking/making sure everything looked good and within specs , nothing sticking , looked great
My issue is the one/two shift after the Tranny is warmed up and placed in Park/Neutral etc. been an issue for a few years
In order to get it into second after the Tranny is placed in Park or Neutral , then back to first or drive you have to bring up the Rpms way high in first before it will shift
The kicker is , after this initial first time , the Tranny shifts perfect , just like it should in Drive , Low Rpms , even manually first to second no matter what Rpms , it shifts perfect
However anytime i place the car back into Park or Neutral , and then back into Drive or First - I have to bring the Rpms way up to get it to shift into Second Gear (Second / Third has never been a issue)
Then once this initial shift is taken care of High Rpms , i can again shift manually first to second at any Rpm i want - Or Drive it does it likes it supposed to at Low Rpms/Low Mph
So why the High High Rpms on the First/Second Shift Manually or in Drive INITIALLY after placing the Tranny in Park/Neutral ??? Then after that it shifts fine at any Rpm
Doesnt make sense to me
Drives me nuts

Correct me if this is not right, but when you say "late shifts" I take it that this is "Drive" and not manually shifting the transmission.
The shift valves sort if ballance the throttle pressure and governor pressure. The governor pressure is supposed to increase about 1 PSI per MPH, and the throttle pressure increases with throttle opening position that is why the car shifts earlier at a certin MPH (or output shaft speed) with little throttle opening, but the shift is delayed to a higher MPH (higher governor pressure) when you stomp the accelerator.
Anyhow, if there is restriction or seal leakage in the governor circuit, the pressure will not increase with the output shaft speed like it should. You may be able to adjust the throttle pressure linkage to make the trans shift sooner (reduce throtle pressure), but that also reduces the pressure going to the clutches and servos so the trans will not shift as hard. Since the valve body is out I would disasemble and clean it making sure all the valves fit well and do not stick.
The governor and governor filter (if equipped) can be removed and cleaned with the trans in the car by removing the tail shaft. If the governor support sealing rings are bad (cracked or excessively worn) the output shaft has to be removed (meaning complete trans disasembly.)
With the valve body out you may be able to try pressure checking the governor sealing rings, but I don't know what would be the pass/fail criteria?

I pulled the valve body and re-adjusted the regulator to 1 5/16" then reinstalled but it made no difference at all still acts the same.
Noticed this sleeve needs to be installed properly (see pic) to prevent late shifts, so I'm going to pull the valve body again and check it.
Cannot remember my instructions mentioning that at all.
Doesnt show up in the B@M Instructions either
You would think if it was installed backwards , would not slide into the valve body all the way on that valve ???
I remember looking at this when i just had my valvebody out , and i remember that sleeve sliding in and out of the valvebody on that valve when i was playing with the pressure lever/kickdown seal
Would love to know if i installed it proper the first time - That Picture you found explains it well - A week late for me , but
Your shift issues - Happen all the time , late shifts ??? Or just on occasion - What Rpms does it shift out at ??? If you manually do it from first to second , does it shift right away , or do you have to reach a certain Rpm all the time ??? Anyways let me know what you find out , might have to pull my Valvebody again , but mine only does it initially , after that its fine as long as i dont go back into Park or Neutral

When I first start out while tranny is still cold it shifts into 2nd at around 3500 rpm and then 3rd around 5500 rpm whether shifting auto or manual.
After it shifts then it will shift normally even after set to park and then starting out again but if it sits for 20 minutes or more it will start all over with the high rpm shifts and it does it consistantly.
I'm going to pull the valve body apart tonight and go through it with the instructions John posted.
It seems like something is sticky and shows up when the fluid is cold/thick and runs fine when hot/thin.
I'm glad I installed a drain plug in the pan.
One more symptom it has, it will not automatically down shift but I can manually down shift. I've adjusted and readjusted the kick down linkage evry which way but loose with no improvement.

You're right, the sleeve will not slide far onto the valve if its backwards. I was hoping to find mine backwards but there's just no way to screw that up.

Does anyone know the procedure for removing the governor with the trans in the car?
remove driveshaft, catch the oil, remove speedo pinion,take off 2 trans mt bolts, jack up trans in front of crossmember slightly, remove crossmember, take out 2 large phillips screws/plate underneath to access the snap ring,take out largest housing to case bolts, expand snap ring to let the housing come back/off, mini C clips hold the gov weights on.

take em out, clean them off w solvent, check for burrs/free movement (though not likely), blow dry, lube w trans fluid and reinstall in the same order and there's only several pieces so it'll go easy for you. a piece of grit could be hanging them up but I'm thinking the prob is much more likely in the VB/kd linkage but Kunkel and others have you covered there.

1bad68, I would scrap that valve body; the scoring in the valve bore isn't good, it has to be leaking fluid pressure past the valve.

I agree with John and as a side note, you don't want to run a wire brush in the bores, the corners should be nice and sharp to keep tiny particles from wedging between the valve and the bore. Also you don't really want to clean the valves with anything that will take the sharp corners off. It will make them slide nice and easy on the bench but can cause problems when running.

Did you dig into it any deeper ???
Remove the tailshaft/governer etc.
Anything else
