Hi folks im new on here iv got hold of a 95 supra auto jap import I love it , but it’s got a problem with the auto box

problems im encountering

o/d light flashes sometimes?

While driving the car will sometime goes crazy and only selects first gear I take my foot off so it drops the revs sometimes it will go into second others it won’t?

With the help of this site iv done the self-diagnostics test the engine light flashed constantly but the o/d light flashed code 61 speed senor 2?

Can anyone shed only light on this will the senor cause me only 1 gear? Sometimes it drives fine maybe indicating a lose wire or something?

Could old transmission fluid cause this problem as I think it hasn’t been changed in 10 years cars only driven about 20k in 10 years

 

any help please ?

Sounds like you've answered your own question. The fluid should be changed along with the autobox filter/strainer. The ATF fluid should be red in colour.

Id start with changing the fluid and strainer and checking sensor connections whilst you down there.

The speed converter most likely sits behind your clocks. You can't miss it! It'll be a non-standard looking part that's spliced into the wiring.

 

It converts the speed sensor signals to make your speedo read MPH instead of the original KPH. If it develops a fault, then your ECU will be getting all sorts of conflicting info, this causing odd shifting.

 

This us why the suggestions above are to disconnect it and go for a drive. Your speedo will read KPH. If your odd shifting is cured, buy a new converter. If not, look elsewhere!
