th350 leaking

[renegadecanuck]

Hello everyone. we finally started work on my truck. Had it parked in my brothers yard.when we went to move it we noticed a large purple puddle under it....oh oh!.
I had to put 3 liters in the tranny before it would move. we checked all the lines and they were good, we took of the pan and cleaned it and reinstalled it, but it still leaked. we decided to take off the tranny and with the help of my nephew and niece, we had it off in no time. my brother suspected the seal might have been damaged. oh yeah, did i mention the tranny was rebuilt last fall and maybe has 5km on it!. when we had the tranny on the bench we took a look at it. the seal looks ok. the o-ring looks like it could be replaced.we cleaned up the "front plate" where the front shaft is. and we noticed that it was weeping along the bottom edge of the plate.
now, about the only thing my hasn't worked on is transmissions. he has done a lot of work on my vehicles and others. he just finished putting on a new carb and manifold on my truck, last winter the truck would not run, and now with the new carb it purrs lol.
but anyways my question is,how hard is it to take off the front plate.we think it might be the gasket is damaged. we took off all the bolts and tried to pry it off. we did not want to use too much force, so....how does it come off?

With the bolts out, You will find 2 of the holes in the pump housing threaded. I think you need5/16 bolts???. thred them in, Pry on em, It should pop out. Just keep the trans upwright,the bell housing up. If you do not, you have a good chance of the clutches not lining up and the whole mess falling apart.
If I were you I'd find someone who knows a little about them To help.
Where are you at?

the closest place that does transmission work is 4 hours away. we planned on calling them but they won't be open until monday. we were going to get a new seal and o-ring sent up.looks like we need a gasket to.

i thought the entire tranmisssion had to be pulled apart to remove the pump?

i just finished rebuilding a 700r4 and thats how it was..

well, i decided to send my transmission back to the place that rebuilt it. we did not want to take a chance on a simple job turning into a big job.

we got the trans back in tonight, the place where we had it fixed before replaced the o-ring behind the torque convertor. tomorrow my brother will hook up all of the cables and odds and ends. when i get off work tomorrow it should be ready to fire up.

not as long as its sitting upright w/ the bell housing up... and its the same for 700r4's you dont have to take the whole trans apart to get the pump out.
