i strarted it up this morning and it started puking out tranny fluid all under my truck. its coming from inside the inspection cover of the torque converter, i would have opened it up and looked, but the bolts were real friggin tight. anyone have any idea what is goin on? it only comes out when i turn the engine on and its a pretty steady flow. i really hope its not a seal or something.. HELP!!!!!

Update- ITS THE SEAL! DAMMIT! FRIGGIN STUPID ASS AUTOMATIC TRANSMISSION AAAAAAHHHHHHH!!!! wait, where is the plug supposed to be on the torque converter?

Re: Urgent TH350 help needed!!!

Are the lines going into the tranny from the cooler tight or broken?

What about the little rubber plug/seal for the dipstick tube?

Other than those ideas, I'm out!

Sounds like the seal to me. Gonna have to at least pull the tranny back to get in there and see what it is. Seal is easy to replace, (once you can get to it) hopefully the converter hub isn't grooved.

Re: Urgent TH350 help needed!!!

Another thing besides the seal you might want to check.... the torque converter I got with my rebuilt TH350 has a drain plug in it........ make sure that hasn't fallen out. If it has at least it should be in the bottom of your inspection cover and be able to put back in without pulling the trans.

Re: Urgent TH350 help needed!!!

To replace the front seal you have to drop the tranny, pull out the torque converter, then remove the seal and install the new one. Reinstall torque converter (spin it several times while pressing in on it until you feel it "click" into place to make sure it's fully seated in the pump again) then reinstall the tranny.

And don't forget to lube the seal with grease before reinstall. (if you ahve to replace it) Vaseline apparently works, although the special tranny goop is supposedly a bit better.

Re: Urgent TH350 help needed!!!

The tip of your input shaft might be bunged up and won't hold the o-ring so all the fluid being pumped into your TC is leaking.

well, i think i found the problem. check first post for update, and please, if you have done this before, please tell me and tricks or anything that you came across? the leak was coming from behind the Torque converter, is the plug near there, or is that definately the seal? anyone want to buy a blazer? just needs some tranny work...

Gee, thanks for the encouragement. when i turn the engine on the fluid really pours out, not just drips, it is a real steady stream, is that what ussually happend when the seal goes

No real tricks. The front seal is just like a pinion yoke seal, or the output on the tranny. (you can see that one on a 2wd vehicle, if you want to get an idea before you tear it down)

Sharp screwdriver under the lip of the seal, pound on it until the metal ring buckles, and pry it out.

Reinstall, you can use a hammer, but you have to be very careful and slow not to warp it. (tap all the way around until it gets started in the pump, then you can hit it a bit harder)

Lube seal with vaseline, (I'd say axle grease or similar if it was a pinion yoke seal, but I wouldn't want that in the tranny) and replace the converter. Turn converter while wiggling it, and pressing slightly in. Should be three distinct "clunks" as the converter seats fully. Shouldn't be able to get your finger behind the converter when its fully seated.

I've had good luck using a piece of rope (or tie down strap) over the top of the bellhousing, and tied over the front of the torque converter, to KEEP it seated when you go to re-install the transmission in the vehicle. Then just untie it and remove when you get it bolted up.

Never know, the seal may just have pushed out itself. That was supposedly common on the early 700R4's and 200-4R's, but not so much on TH350.

I'd say it's definitely the seal.... the plug on mine is located along the outer rim on the engine sideof the converter... you would see it if you turned the converter... have never seen one on a converter before this one
