    how difficult is it to pull the transmission and re-install it on a 93 suburban. I'm fairly certain mine is toast. I have removed and reinstalled a transission on a small import car, never a large truck. i'm a decent shade tree mechanic. any tips or tricks?

    The T-case and trans as a complete assembly is real heavy, I recommend separating them before removal.
    I'd use a trans jack to do the job if at all possible.

    Not too difficult of a job. Not fun by any means though.

    What is the current trans, and what is your plan for repair? Junkyard transmissions are a huge gamble. Make sure you flush the trans cooler in the radiator, and replace the stacked plate cooler in front of the radiator.

    Its more physically demanding than mentally. Pretty strait forward job. If its a 93 its a 700r4. I wouldn't buy one of those out of a junk yard seeing as they are all junk..I'm about to put the 4th trans in my truck. Smoking one about every 30k since I build the engine..I would find a good trans that's build up otherwise its a lost cause

    well the tranny leaked tons of fluid when I was pulling a boat. I mean tons! put 10qts through it in 30 miles. I have degreased it and am about to slide under and see what caused it. I had heard these transmissions were weak and if I do decide to replace it, it will be with a rebuilt- not going salvage yard route. With that much fluid coming out, I'm hoping I just blew out a gasket or line broke somewhere....

    fluid seems to be leaking from the weep hole on the bellhousing... what does that indicate?

    Front seal or pump seal. Either way, the trans will have to come out.
