The gear box been acting funny lately. I recently changed ATF oil, but this seems to be an tranny ecu issue.

When move the lever to M mode, during lower rpm, the car will upshift from 1st to 2nd without my command. Same with 2nd to 3rd. I know the car default gear starts at 2nd, but when I select 1st to start, it will act on its own.

In regular D mode, is drives fine with no problem.

Could the shifter wires on the steering been getting old and need replace?

Anyone here experienced similar problems? Any input will be greatly appreciated thank you.

 

Sorry, I was hoping for discussion on double D's...not regular D mode.

freudian slip there eh?

 

Could be the switches. Could be the shift lever switch needs adjusting. If it would be on the verge of switching back to d mode I could see it acting like that.

 

They should have utilized a leather shift gaiter to protect sensitive selector components. The selector linkage is very delicate when you have to open it up for debris.

Isn't it dependent on being sport mode or not?as well as PSM ON Or PSM OFF?
