Thread: TCI Glide - Trans-brake roll

  1. #1

    TCI Glide - Trans-brake roll

    My TCI pg tranny is getting pretty wore and I plan on having it rebuilt this winter, but I'd like to get a couple more weekends out of it before then. I've tried adjusting the tranny, but at best I still get a 6 inch or better roll. Other than running a line lock/roll control thru my tranny brake switch, is there anything else I can do to stop the roll for the time being? Thanks...

    You might try turning the idle speed up. That should let the pump build more pressure and set the brake quicker....

    You can try idling like said but it sounds like the reverse clutch patch is not kicking in like it should. Can you adjust your solenoid?
    Has it always rolled? If it a seal issue on the reverse drum maybe you can try some of the addive that brings life back to the seals?

    I had already tried bring the rpms up, but that didn't help. Thanks...

    What do you mean adjust the solenoid? The roll just gradually got worse over the summer.

    Some of the solenoids are adjustable. The solenoid engages the reverse piston so if you adjust it, it may apply it better? Not sure worth a try.
    Seems to me the reverse clutches are worn but if you had some extra pressure there it may help hold. :?:

    If raising rpm didn't help, then you either have a pressure problem or the reverse pack has too much clearance/worn out. Probably the clutch. If it tried to back up with the brake set, it'd be a band issue.....

    Curious where do you have it set ?

    Try to footbrake the thing in the beams then set the brake, maybe 2000 rpms doing so. Its a band-aid fix but higher the rpm the higher the pump pressure.
