    So today I drove back home to the Roanoke area from Montgomery Alabama in the truck.

    Houston we have a problem.

    While climbing the hills on I-75 heading north from Chattanooga my torque converter slipped while locked up in OD. Then a little later it slipped some more. By the time I reached Bristol it was slipping regularly on the steeper grades.

    I've known it was on the weak side since I got the truck back on the road but it's not slipped before.

    I suppose the solenoid could be intermittently unlocking and need to check that before making any decisions on what's wrong but my gut tells me it's tranny time.

    If I've got to pull it I intend to go through it thoroughly and upgrade any hard parts that are deemed insufficient. Also going with a triple disc converter.

    And I noticed what I thought was a metallic tapping on the drivers side so thinking I'll pull the valve covers and inspect the valvetrain too.

    It's hell catching up on maintenance when one of these things has been neglected as long as this one was.

    ouch, it always sucks when something big like that is failing but it sounds like it was no surprise. but at least you got it home safe and can plan what to do next.

    Yeah I really need to do a proper troubleshooting on it. Check the solenoid connector, pull and reset the codes and then see it it's still doing it.

    Didn't have any shudder when it slipped, and yes I know what that feels like, so it may just be electrical. Hoping that's the case and the clutch was just locking and unlocking.

    But knowing what I want to do in the near future building it stronger is going to happen at some point anyway.

    There’s a good tech article on installing the transgo tugger (think that’s right) kit. @trackspeeder is probably your go-to for auto trans related issues/suggestions.

    I can understand this one. I'm playing the same game with mine.

    Probably all of us... Unless you bought it brand new off the lot..

    Feel your pain, I was having issues with mine, got lucky and just needed a flex plate and did a few minor upgrades while I was there.
