Pressure and return line on TH350 and dipstick seal

[jekquistk5]

Which one is which? I have an issue with loosing fluid and I think its due to the extra cooler and I have the lines reversed. Basically every time I go to drive the truck I have to add about a qt of atf to get it to move. I believe I have the return and pressure lines switched up. I know in a perfect world I could get the dipstick oring to actually seal, but I have tried about everything and cant get it to seal 100%. So it leaks out. Then when the pump pushes fluid to the cooler and then there is not enough for it to move.

Thoughts and Ideas?

Switch them at the cooler and see if it changes

Edit: I totally read this wrong. Ignore please

Apparently off the TCI website, post I saw the link no longer worked:

TH350, TH250
Fitting Location Thread Size Flow Direction
Upper ¼" Pipe Return/in
Lower ¼" Pipe Cooler feed/out

Upper return lower feed. Did your dipstick always have an oring? There are 2 styles.

and fyi o-ring SUCKS

also dipstick only from 700r4 gets you a locking one on a th350 .

Had the rubber one but it was cracked. bought a lokar stainless flexible one with the oring to fix my leaky problem and it didn't.

You can get the replacement top-hat style seal in the Dorman/Help! section of any parts store.
