74 torino sport transmission

Basics:

try a little brake fluid (like 1/8" cup)poured into the trans.  it helped me w/ a similar issue and has worked for several years now.  it has conditioners in it that help seals and such.

Brake fluid is what used car dealers do to cars with slipping transmissions to make them drive for a few hundred miles so they can get rid of the car. Don't do it. It will only make things worse. Brake fluid is hygroscopic and will suck up all the moisture in your transmission and contaminate the fluid with it. Not to mention the corrosiveness will cause rapid additional wear. Sure the clutches grab better and the car becomes more drivable, but it's a temporary fix while the fluid eats up every friction surface it comes in contact with.

I put brake fluid (about 2 table spoons) in 3 1/2 years ago.  It was slipping bad enough when cold that i could barely get out of the neighborhood.  After brake fluid, it stopped slipping immeadiately.  Changed the fluid 2 1/2 years ago and it started slipping days later.  Put more brake fluid in and it hasn't slipped a bit since.  Car is daily driven, 400 c6.  Cheaper then a re-build.

I hope this is the only time I ever have to say this here, BUT...

YOU'RE DUMB AS HELL!!!

As for the OP, check the fluid (if there is any to check) to see if it smells burnt or looks brownish.  If it is either brown or smells like burnt then you should most likely change out the old fluid and change the filter.  This will be a rather messy job but it will give you a baseline to work with.  Also don't forget to drain the fluid from the torque converter by removing the small access cover located just behind the oil pan, bolted to the bell housing.  Once that access cover is off you will need to rotate the motor by hand until a small hex bolt comes around, that bolt is the converter drain plug.

Good luck!
