On the side of the trans are pressure plugs to test it,find the one that has pressure in low gear,plumb it with hydraulic hose to a gate valve,then back to the pan from there,this should work.I can't remember which one is low but i bet it's the one closest to the rear,i know the one closest to the bellhousing is line pressure from the pump,not sure if you can use that one.Where did you get the coupler?

Wouldnt you want to dump the pressure from the pump? If you only tie into low what happens when you put it in reverse?

tci sells the pump drives.
05 the way i understand it is when you open the valve it can't build pressure so it won't move in any gear kinda like when you blow a cooling line and dump all the fluid out or like when the filter is clogged and it won't move am i on the right track here?

We actually have a valve body for a TH-350 direct drive setup. The part number for it is 321110. It is a reverse pattern with engine braking full manual valve body that allows you to run a direct drive without any external lines.

The valve body runs around $222.00. It will work in any model TH-350 except the lockup style.

Whats the weight difference?
And what about other issues related to durability??

I have wondered myself why there arent more th350s running around the tracks...

The th-350 weighs around 20-25 lbs. more than a glide, but with it's 2.52 lo gear it is perfect if you are limited on rear gears. You don't see alot of Th-350's in cars that can run direct drive because of having to run lines and ball valves. They are a pretty durable transmission. Most all of the truck series in the southeast require a TH-350 trans. But until this year they had to run a torque converter. So we came up with this valve body so they could run a direct drive setup. I actually have a few guys in on the east coast that are running this on dirt.
