Change tranny fluid ( there is a pump required to get all of the fluid) If thats not the issue there are kits to help shifting. Awards

Where it plugs up looks like a small rounded top can. There will be a small tube sticking out the top. Check there and at the intake manifold near the carb. You'll need two people, one to crawl under and wiggle the vacuum tube and the other to look at tha motor and trace the tube up to the manifold.

I will check my manuals at work to see if there is a pressure tap for third gear clutch pack pressure. Some guys are using the Trans-Go shift kit , but I think it won't help for long, you can't usually repair a trans with the contents of an envelope or bottle for very long. You might want to find a rebuilt or a good core from the bone yard and do it your self. If your vacuum pump is worn out, you will have a hard brake pedal, unless you have hydra-vac. I think that big blonde chick may have hydra-vac too,just sayin'.

It only shows line pressure, so it probably wouldn't help narrow it down to an individual clutch leak. All three clutch packs are engaged in third gear. Is the slipping only occurring during the 2-3 shift, and then third locks in after that?

After 71 they changed the seals to teflon, which become brittle after a while because of heat cycling. Just make sure it is to the top of your full mark, not in the middle, sometimes with older vehicles, especially diesels can wear out the transmission mount causing the tail of the trans to sit a little lower than it is supposed to, causing the fluid to all move to the back of the pan. While the dipstick and filter/pickup, is toward the front of the pan. So anyway, just make sure it is full, it may not being getting enough fluid if it is not.

In the shop I worked in it was a general rule that if a tranny hasnt been regularly flushed and it has over 125k miles we would insist that the customer NOT get the flush as it COULD lead to having to rebuild the tranny. just a thought for ya Awards

Th350 has a vaccum shift thing on the side if the vaccum lines not hooked up or has a crack it will make it slip when it shifts.
