    They're putting in a hardened shaft. But when I asked them to do away with the lock-up feature, they look at me funny. Time to find a new mechanic.

    Re: Drive your cars!

    LOL - yeah I agree. (that would require a different convertor too.....and more $ of course) Hope they don't rape you to bad....

    Re: Drive your cars!

    Hopefully your line pressure was OK (too high can kill a trans, just like too low) Some 'shift kits' raise the line pressure to get firm shifts. Some (like trans-go) raise it almost too high. The TVS adjustment also regulates line pressure.

    How much power are you making? It is the torque that is the limiting factor, not horsepower. The stock input shaft is good for around 450 lb/ft torque. The hardened input shaft is good for around 550 lb/ft. First and Second gears use the outer input shaft, and Third and Overdrive use the inner shaft, which is why you still had First and Second, but no D or OD.

    I'm running the hardened inner shaft, and the Baumann shift kit, in my custom wide-ratio AOD behind a healthy 393W. Normally a high-stall converter softens the drivetrain shock to the trans at the shifts. Even with a 2500-stall converter in mine, it is enough to bark the drag radials on wide-open 1-2 and 2-3 shifts. Think about that - I am putting enough power through that little 3/4" inner input shaft to bark the tires when it goes into Third. (in an AOD, lockup and Third happen at the same time) I'm gonna have to do something about that... maybe a higher-stall converter since that will be 'looser' and that should cushion the shock through that inner input shaft at the 2-3 shift...

    Re: Drive your cars!

    have them run a pressure check on it and see that your pressure levels are set to coincide with TV lever postiion/shifts. (Assuming you don't have an aftermarket valve body here) that TV lever adjustment is critical on a stock VB as it is what sets the pressure for the shift points. If that cars seems early or late on the shifts at any point DO NOT drive very far! Check the TV lever for travel and adjust it.

    Re: Drive your cars!

    They had to put in a new convertor because they couldn't get the broken end of the input shaft out. All in all it cost me half as much to get the tranny repaired as opposed to what it cost me originally. I asked them about the warranty and they said it only covers the wetted parts. Last dyno tune was 287.58 HP @ 5400 RPM, 310.38 FT-LBS @ 4500 RPM. All that is at the rear wheel I presume. Not sure what it's putting out at the flywheel. The mechanic told me the tranny could handle 500 HP. I highly doubt the motor is putting out that much. One of the comments made was "that it is a heavier car" that what they normally put this tranny in. Told the owner what I thought of him and his shop and that he lost a customer as well as any references. Looks like I'm back to wrenching on it. Right when my knuckles are healed up and the grease is gone from underneath the fingernails. It just flames my a** that I can't seem to find a decent mechanic that I can trust.

    Re: Drive your cars!

    Jeff, it's holding up. Haven't really jumped on it too much. There's a vibration in it now, and I've noticed that the drivers side export brace looks tweeked. The lip on the firewall that the brace bolts to is pulled down. Still pretty pissed with Higgins, but I'm trying to let it all go and move on. Lesson learned. Come on out to Oz Pizza in Douglasville this Saturday between 2 & 5. Having a cruise-in. Staring to get a few cars to come out.
