right I have a problem with my NSX.
now i don't want this to become one of the many 'autos are crap get a manual car' threads as they don't help!
i've a '92 auto, 100k miles and the box has gone down. symptoms thus... was driving ok, gears as normal in D, then got to a junction, gently accelerated out and flared into second and lost drive. stick pulled back into 3, still no drive until the engine revs let to idle, and then it 'catches' and i have drive in 3. shift back to D and lose drive again, so limp home in 3. ok so the box is probably worn out, so half expected.
so get a replacement 'low mileage box' as ALL second hand ones are. Fit it and it all works fine, smiles all round, gears shifting as they should, I can even feel the downshifts slowing to a junction (the old box was tired!) but after few miles, i do a turn gently accelerate (easing the new box back into service!) and lose all drive. switch car off, restart and i have all the gears again for about a mile, then lose drive. switch off, restart, and continue the loop!
now i could be unlucky and got a second bad gearbox, but could a controller be the cause? not getting any fault codes up, not flashing dash lights. I have tried a second AT ecu, does the same thing. what else could trip out the box? TCS off still does it.
unfortunately there's not alot on the searches, apart from the one suspected blown by a trackday spin, and all the others suggest a manual conversion...
has anyone got any ideas....
just to add, daily driver, fluid levels good!
