TH350 will only go into reverse

First my apologies if my english is not always perfect.
Today I tried to fix my brothers chevy styleline, which has a transmission problem. Because the leakage through the gasket has become worse some time ago the transmission run low on oil, my brother had to fill it up every time he went out for a spin. I don't konw if this has to do with the problem, but after some time it became harder to start driving. The engine had to be revved up to about 3000 to 4000 rpm to get it rolling. When the engine and the transmission warmed up it became much better.
But two weeks ago it jumped out of gear and into park, I removed the drive shaft and towed it home. Because I wasn't there when it happened I thoughed it had something to do with the low oil, but today I saw that the shift cable was torn so the inner cable came out the outer cable. I fixed this and the transmission wil go perfectly into reverse, but not into drive. I also tried to put it into the first or second gear, but it doesn't move at all. Is it possible that the transmission is burnt?

The torque converter is a TCI saturday night special and the shifter a TCI streetfighter.

Can anyone help us, there aren't much people here in the Netherlands that really know anything about automatic transmissions

automatic transmissions driven low on fluid will slip and burn up frictions quickly.


IF the transmission worked better warmed up, this is an indication of hard/old internal seals.

Is the fluid dark color? Does the fluid smell bad? The fluid may appear good if you have added many quarts to the transmission

Sounds like the transmission should be disassembled for inspection,

at minimum , pull the pan for inspection of debris

Oke, that's what I was afraid for. The fluid looked dark indeed and someone said it smelled burnt, so I think he was right. If the internal seals are old is it then still possible that it will go into reverse that easy?
I will see if I find the time to pull out the transmission this week.

Thanks

Last week I pulled the tranny out and tonight I opened it. Crosley, you were wright, the forward clutches are completly burned up. There is no friction material at all on the plates, I only see a lot of debris in the forward clutch housing and on one plate still some friction. Because the transmission is rebuilt only 2000 miles ago I was planning clean the transmission and put new forward clutches in, or does anyone have a better idea?
