    Oil Pump, new style versus old style,

    Guys, sorry to revive an old thread, but I had a quick question before I get too far into re-assembly. My replacement 2nd design timing cover has a huge chamfer compared with the images I see of the OEM. There is a chance that the inner tube diameter was just smaller, which exaggerates the...

    diagnosing TCC lockup issues.

    I threw it in 3rd gear when there were either a lot of short but frequent or long inclines, whenever the truck felt a bit bogged down. It never once wandered between 3rd & 4th a lot. 99% of the time it was in D though. It would either shift to 3rd while going up an incline, or stay locked...

    diagnosing TCC lockup issues.

    Hey guys, I've been dealing with this issue for some months now on the family's DD. Is there a good way to test for a bad torque converter, or if the problem lies in the transmission? The trans currently has about 260,000 miles on it. I rebuilt with new seals and clutch packs, and a new...
