    I just did a head gasket on my '96 80 series and I am a bit stumped. I went through just about everything on the top end. New heater hoses (including PHH), milled the head, new seals all around, new injector o-rings, ARP stud kit, etc., etc.
    Everything went together nicely. Engine is back up and running smooth.

    Took it out for a test drive and now she won't shift right. First gear will wind up to 4,700 RPM before shifting to second. I have the same pattern for second and third gear. It doesn't matter if I shift through the gears manually or not the pattern is the same. I have adjusted the throttle valve cable. I can get the shifts to soften a bit but the shift points stay at the same rpm.

    I have checked the trans fluid levels hot and cold so I know it's not a fluid level issue. I have done an exhaustive search here on Mud as well as Google without much luck. :bang::bang::bang:

    Are there any 80 Series ninjas here on Mud that can lend some advice or additional trouble shooting?

    I'm about to round up an old priest and a young priest to exercise the demons out of this thing :mad:

    Did your "power" button down by the gear selector get bumped? Maybe the indicator light is inop.

    Check your "kick down" cable adjustment.

    Power button is not the issue. I checked that as one of the first items. I have also checked and adjusted the throttle valve cable to infinity and beyond. I can soften the shift but the shift point never changes from shifting right near redline through 1st, 2nd, & 3rd.

    The only thing that my collective posse has been able to come with is to move on to check the throttle position sensor.

    I noticed on my Torque app, that the throttle number stays stuck at 94.

    Thanks for the thoughts and feedback. I am open to anything else.

    I have downloaded the '96 fsm. Any help on trouble shooting the TPS in conjunction with tranny would be greatly appreciated.

    Yeah, I was gonna say, "TPS out of adjustment?".

    does it feel like the tranny is slipping?
