SupraTTBPU Posted June 8, 2020 Share Posted June 8, 2020 Hello everybody, I had a problem with my automatic transmission last year (reverse gear did not always work and also bad shifting (O/D blinked). (Code 63) http://www.mkivsupra.net/vbb/showthread.php?352807-Error-Code-63-automatic-transmission-bad-shifting I then bought a used automatic transmission and installed it on Friday. Unfortunately, it was not successful Reverse gear did not always work again, and the transmission did not shift as it should. [This time error 63 and also 62) so both shifitng solenoids ] I am now wondering whether it was really due to the gearbox? It is exactly the same mistake. Is the fault possibly in the control unit? I read something about leaky condensers that some of them also had this error. I have now opened the ECU and all the capacitors actually look good, except for the one in the picture. Or is it bad. What could possibly also trigger the reverse gear problem? Please help thank you and regards from Germany (my car J-Spec Single AT) Quote Link to comment Share on other sites More sharing options...
rider Posted June 8, 2020 Share Posted June 8, 2020 I've only had gear selection issues with a much newer Getrag auto gearbox that turned out to be low oil pressure after changing a whole load of oil and other expensive parts. That was a pain and expensive to diagnose even when the more modern boxes provide a lot of live data to work with so good luck tracking this down. Pending some pearls of wisdom there are a couple of old threads on the lack of reverse problem that may be worth reading through. One supports a problem with an ECU. Your capacitors don't look like failed ones from anything I've ever seen where the capacitor body has either swelled or had fluid weep. http://www.mkivsupra.net/vbb/showthread.php?333126-Auto-Gearbox-issues-and-ECU-s http://www.mkivsupra.net/vbb/showthread.php?283708-No-reverse-gear-Autobox-need-help Quote Link to comment Share on other sites More sharing options...

rider Posted June 8, 2020 Share Posted June 8, 2020 There is one for sale on eBay for £995 plus postage. For that price I'd probably prefer to test the unit first in another car or send it off for testing. If there is no circuit board damage you can buy a garage full of capacitors for that kind of money. Quote Link to comment Share on other sites More sharing options...
