Did you try flushing your transmission?  If not use Dextron/Mercon fluid only as the newer fluids are too thin.  The TV rod adjustment along with a trans flush should fix that issue.

The trans was supposed to have been removed and disassembled and a kit installed.
That should have flushed it about as good as it can get, however judging from some of the other things I have found, its possible I was lied to.

Also, in the event that it is rebuilt and the wrong fluid added would that keep it from shifting?
Is there an additive that you can add to thicken the fluid?
Or will the Dex/Merc stuff do the trick?

If they added modern Dextron it is too thin for these older transmissions.  Its possible that its not providing the proper pressure to open/close the valve body.  I would drain out the trans fluid, add Dex/Mercon fluid, and try again.  If your still having issues its possible that:

1.  Someone polished the valve body when it was rebuild.  There is a discussion on the CLC website about this and why it can cause problems

2.  Someone failed to install something or installed it backwards

3.  Nothing was ever done to the transmission

If I had to guess, they would have added DEX III
I was told that the shop that did it worked on mail delivery trucks based on the S-10 chassis

Dex III is what's supposed to be added.  Dex/Merc III are the same.

The power seat does not work. I need to figure out the wiring. I used a small gage jumper wire from the battery and touched it to the pigtail of the seat but all it did was click.. No movement. I think I need a main heavy wire connected also, as I think I just activated the switches but did not engaged the motor power.


On the power seat, the switch makes 2 contacts, 1 for the seat motor and one for the solenoid.  To test is you really need to run the power through the switch.  All the same they most get gummed up with old hardened grease get stuck.  Many times you can take the seat track apart clean out all the old grease, re-lube and it will work.   

And then for the biggie.
The transmission still does not shift.  :(
I need some advice on the Hydramatic.
From what I have been told, these are 4 speeds. 2 lows and 2 high gears.
It appears to have the 2 low gears but no high gears.
Reverse works.
I was told that at wide open throttle the pressure rod needs to be all the way extended. I made this adjustment but it did not cure my problem.
It was SUPPOSEDLY rebuilt before it was shipped. I do have a rebuild kit box and its full of used parts so I think its got a new kit in there, but just not adjusted properly is my hope.
Also I think there is an used governor in that box of used parts.
What, if any other tricks, can you guys recommend I try on this thing to get it shifting through all the gears?

It may sound basic, but make sure the transmission is full.   Iíve had mine not shift when the fluid is low.   Because the pan is so big you can have a really low fluid level and still have it show on the dip stick.  A good diagnostic aid is from the manual attached here.

Thanks for the service manual pages and the seat info :)
Q: how many quarts does the trans hold?

Page 2-8 from the shop manual: dry: 11 1/2 quarts. Refill: 11 quarts.
