    Default vp wont change gears unless over 3500 revs

    My vp auto wont change gears unless it goes over 3500 revs. It was changing fine until I parked at the drive-ins on an angle. Then when I went to put it in gear there was a clunking noise and now I have to floor it for it to change gears but when it does it drives like it should.
    Also when it does change it shifts hard.
    Can anyone help or offer any ideas as this has me stumped.
    Cheers

    On older trannies on various other cars this sounds =exactly= like the vacuum hose has fallen off the vacuum modulator on the tranny.
    Do these have the same setup?

    I checked the fluid level and it was fine. I am going to take it to a transmission place tomorrow and see what they have to say.
    Will post what they tell me.

    or the TV cable is stuck put car in drive or reverse and get someone to hold foot on the brake and pull the cable to the trans a heap of times to unstick the valve in the trans

    Just got back from the trans place and he said it has a blocked throttle valve. Does anyone know if I can do this myself of do I have to get the trans place to do it. If I can do it myself how would I go about doing it.

    do as i said above pull the cable lots of times with car in gear running it will unstick the valve .it may stay unstuck for ages or jam back up fast its a common problem with t700 transmissions all transgo shiftkits come with a self cleaning TV valve assembly to go in the trans to fix the problem

    This morning I was going around a roundabout and it started to rev out so I put my foot to the floor and now it is driving like it used too. The valve must of got unstuck somehow. I will still buy a shift kit but for now I have some of the electrical problems to fix first.

    Go the stage 2 transgo kit bets ones you can get with a corvette servo, certainly puts the t700 back into action. Id never own an auto again without throwing in a shift kit.
