damar2000 Posted May 22, 2002 Share Posted May 22, 2002 I seem to be have a problem with my Auto Transmission on a 93 twin turbo supra - the symtoms are as follows: Occasionally (usually when cold) reverse is engaged on the gear stick but nothing happens. If you let the engine warm for a few minutes reverse will eventually be engaged on the transmission and the car drives OK. Sometimes when this occurs the Slip control light will start flashing and slip control does not work. The only way to get it working is to reboot (switch the engine off for a few minutes and start again) When reverse will not engage there is a very light (almost inaudable) constant scraping noise from the transmission and the tickover revs are higher than normal. Sometime popping it into Drive and then back into reverse will solve the problem but not always. Any ideas as to what is causing this and why???? Thanks, Dave.

Alex Posted May 22, 2002 Share Posted May 22, 2002 Have you checked the fluid levels and condition? Quote Link to comment Share on other sites More sharing options...
badtoy Posted May 22, 2002 Share Posted May 22, 2002 sounds like burned clutches.....and a bad line pressure solonoid. go to a toyota dealer and let them measure the line pressure of the tranny, thats a 10 minutes job. check the color of your tranny fluid, if its dark your clutches are 100% burned. mine was clear but the clutches and all pressure solonids was gone. :-((( after that you will know exactly what to do. markus Quote Link to comment Share on other sites More sharing options...
Digsy Posted May 22, 2002 Share Posted May 22, 2002 A learned source once told me that if your clutches are burned out, as well as the fluid being dark, it should stink! He didn't say exactly how it would smell, but if you sniff the transmission dipstick and go "URG, BL**DY HELL!" or something like that, then it means your clutches are on the way out, or they have left already. I've sniffed my dipstick, and it just smells oily. Quote Link to comment Share on other sites More sharing options...

damar2000 Posted May 24, 2002 Author Share Posted May 24, 2002 Hi all - thanks for the advice. The oil looks OK (and it smells OK too!) - although it might have been overfilled as when hot the level seems to be above where it should be - although Im not sure whether you measure it by pushing the dipstick right down past the twisty thing or whether it just sits on top of the twisty thing - Ill get Toyota to check at next service. Cheers all, Dave. Quote Link to comment Share on other sites More sharing options...
Guest Martin F Posted May 24, 2002 Share Posted May 24, 2002 You need to push it all the way down, so that it clicks in. Quote Link to comment Share on other sites More sharing options...
Terminator Posted May 24, 2002 Share Posted May 24, 2002 You must check the fluid hot with the engine running and put the selector through nautral and all gears several times before measuring. If the fluid is fried the smell is like burnt toast, I believe. Quote Link to comment Share on other sites More sharing options...
HedgehogSandwich adi Posted May 25, 2002 Share Posted May 25, 2002 I've heard a good way to check the oil is t put some on a bit of kitchen roll, wait 30 seconds, if the oil is still the same as when you put it on (ie uniform colour and not spread out) then its fine. If its gone into a brown ring round the edges then its nackered. adi Quote Link to comment Share on other sites More sharing options...
