Hydramatic Repairs
Yesterday I think the 4 spd. Hydramatic gave up the ghost.....was trying to get out of my subd and it just barley moved. I checked the fluid before it leave the garage and it full, the filter was changed and cleaned about 1500 miles back. Anything else I can check before send it to the shop? I did notice a burned smell when I got back in the garage........
Go figure, it was the onlt part I did not rebuild..... Pointers would be helfull. I have an old time trans shop that knows what a hydramatic in, so I can have it rebuilt. So much for cruising this summer.....

Re: Hydramatic Repairs
Did the transmission fluid turn brown in color?

Re: Hydramatic Repairs
Sound like the overrunning clutch in the torque converter not working. This happen to me. It was very slow to get started. Once it was moving about 30 mph it operated properly.
Inside the torque converter the overrunning clutch (sprag clutch) outer ring had came loose from the housing. You lose torque multiplication and it is now just a fluid coupler (very inefficient).

Re: Hydramatic Repairs
Jake, go to the fatsco transmission parts website to get an exploded view of your transmission. They make many of the needed repair parts for that single range hydramatic.

Re: Hydramatic Repairs
i dont know much about hydramatic's, do you check fluid with engine running?
on other transmission's if the fluid level does not drop when you start the engine, it means that the pump is not turning. could be the pump drive gear, or torque converter? Rick

Re: Hydramatic Repairs
Hi Rick,
Yes you have to check the fluid while the engine is at idle. On Tuesday, I meet with the shop that has exp. With Hydramatics and he'll give an estimate on tripping the trans, repairs and time schedule. I jave no real idea on how may miles is on the trans and frankly I should have had it rebuilt before I put it in the truck back in 2010. A full rebuild kit cost $350 from Fatsco, so it will be worth it.
