TBucket Engine Project (Dart SHP)

Got the trans back in. Before putting it on the ground, I added 8.5 quarts of Mercon 5 ATF. It started and ran fine this
time. I checked the trans fluid and added another quart. Put the car on the ground to test the trans.

Don't have reverse just forward gears. It seems it's still in gear when I put it back in park to turn the engine off. It goes
forward until the parking paw engages when I let off the brake. It's probably still low on fluid, but I don't think it's low
enough to keep the trans from working.

Still want to add more fluid check pressures.
 
Check the fluid level again Rick.

If ok I am thinking reverse boost valve issue stuck.

Forward clutches or direct clutches are welded together.
Valvebody cross leak.
 
Pressure gauge hooked will tell more like you said Rick.

What maybe happened is all the seals got Cooked . The Clutch piston apply seals.
It severe overheated and burped ATF out. That much is known.
 
thinking over the past posts I get the feeling the issue may have been related to improperly adjusted tv cable/ trans control
According to the ATSG 200-4r manual:

No reverse or slips in reverse;
1) throttle valve cable
a) binding or misadjusted
2)manual linkage
a) misadjusted
3) throttle valve
a) binding
4) t.v. limit valve
a) binding
5) line bias valve
a) binding

1-2 shift--full throttle only
1) throttle valve cable
a) binding, unhooked or broken
b) misadjusted
2) throttle lever & bracket assembly
a) binding or unhooked
3) throttle valve & plunger
a) binding

rough 1-2 shift
1) throttle vlave cable
a) not adjusted properly
b) binding
2) throttle valve or t.v. plunger
a) binding
3) t.v. limit valve
a) binding
4) accumulator valve
a) binding

Going by your description and what the diagnostic chart says, I'd be looking at the tv cable again. On the 700r4 & 200-4r transmissions, throttle valve cable adjustment is paramount to the transmission survival. If it's adjustment is off, it can kill a transmission in a mile.

Do the Running line pressure test in all forward gears Rick and reverse.
Check TV Adjustment.
Work the Trans throttle by hand disconnected from the carb.
If bad readings we know why.

The ATF WAS 300-400F Hot to scorch burn the fluid.
You said it smelled burnt.
Fluid was very dark in yout pictures.
Cooked all rubber seals inside.
Then teardown required.
Wasting time otherwise.
 
I am going to pickup more fluid and confirm that the trans is full this afternoon. Then I will be going
thru the adjustments to verify the TV cable is properly adjusted. I don't have the OEM system, I have
the BTO TV Made EZ system with the SS Braided Cable.

In short, the instructions below want the pressure to be 2-4 psi higher with the cable connected versus
the pressure with the cable not connected.

I remember that BTO TV cable kit now that you bought Rick.
 
Nothing seems to make sense about this problem. Below is what I have done.

- Fill the trans with fluid, checking was done in gear and idling. [When in park it's actually in a forward gear.]
- Ran the trans thru all the gears.
- Checked the fluid level again.
- With the rear wheels off the ground ......
+.... P is in a forward gear. The wheels jump forward when I put the trans in Park. I also know this because when I put the trans in a forward gear and let the wheels roll, the idle is significantly higher than when it's in P. This would explain why the trans boiled the fluid when I thought it was in P during the 10-15 minutes at 3500 RPM.
+.... Put the trans in R from D with the tires rolling, the wheels lock abruptly.
+.... Put the trans in N and wheels don't turn, just like in P. Now that I think about it, it could be just like putting it in R and wheels lock abruptly.
+.... All forward gears work as they should. When in D, the trans shifts thru the gears as RPM is increased.

Checked pressure and it was more like 20 psi higher between the cable connected and not connected
at idle. Should be 2-4 psi, but this is effected greatly by the throttle position at idle. Idle was set with
the trans in D and the tires off the ground rolling since the cable position is effected by the position at idle.

After setting the idle with the tires rolling, I loosened the adjusting nuts on the TV cable. When I started
the engine again all I could get is 150 psi, no matter which direction I adjusted the cable housing.

For some strange reason, I feel like another STUPID mistake is about to be reveled.

Funny how itty bitty problems cascade into car changing problems !!!

we all learn by making a endless list of less than brilliant decisions RICK,,
your not alone in that regard.!
the trick here is to avoid duplicating those less than brilliant decisions and learning how to avoid them,
and learn to take the correct option, or action, you should have made.
simple stuff like don,t stick bobby pins in electric outlets , or touch the red burner on the stove, should be easy to learn early!
more complex stuff like never lend your tools out, or when you ask the wife whats wrong and she says "NOTHING" takes longer...
\ but everything's got a learning curve

What is Line pressure in Reverse gear Rick ?
 
Reverse Boost valve should kick in Reverse.
Line pressure typical jumps 40-50 psi higher in most transmissions than Forward or drive.
 
Only things that could have changed since 2 weeks ago is the manual linkage is misadjusted.
TV Cable or BTO ECCENTRIC INSTALLED WRONG.

Transmission Filter is not installed right and sucking air in instead of ATF.

I went thru the adjustment procedure again before this last round of tests. The picture below shows
the shifter linkage mounted in 2013 when everything worked right. It's the same way now. I did have
the console out and it holds the shifter on the other end, will confirm later that nothing changed there.

Will pull the pan before I yank the trans out and check the filter and TV operation.

Yes.
