Default Automatic Transmission not engaging

Hi all,

I've bought a 94 mark IV Supra NA.... Its been given a good hammering by previous owners and still works but with a few problems..

The worst issue is that the transmission slips / not engages when under load (going up slopes) at low speeds

An example would be driving up a slope in a multi-story carpark, I have to go slow to avoid scraping the bottom of the body kit and exhaust on the speedbumps i'm in D (drive) and when I come off the gas and go back on the gas it disengages the gear and start rolling backwards, I have to brake and then gas up up again ....or let it roll back and wait for it to re-engage (no good when cars are behind you)....

I don't seem to have an issue on the flat....

Another (an probably related issue) is there seems to be no kickdown when you floor the gas pedal, it stay in the gear you are in and speeds up without dropping to a lower gear.

All this points to a tranny problem... I checked the tranny fluid and it looked ok (red and not burnt) but it was way overfilled, I pumped some out and it's at the correct level now...

any thoughts ? is a tranny re-build imminent ?


ta,

Addy
