4G91 transmission problem

[black_howling]

I just mod my Iswara to cater to the 4g91 engine. but then there is a slight problem. my transmission seems to be stuck at the 3rd gear and it aint moving from there. the only time it jumps to the 4th gear is when my rev goes all the way to 6+ or 7. Could sumone help me with this???

black_howling, I am running 4G91 auto in my wira, can you tell me more information on your problem?

From my experience in my car, if I driving my car aggressively, the TCU will let the gear stick to 3rd gear longer after I release throttle.

But before my car send for tuning, I used to stick to 3rd gear when I touch 6000rpm@160km/h even though I release the gas pedal, after I sent my car for proper tuning on TPS and other MUT related tuning, my auto gear box now response faster, hope the gear box maintain heathy
