Hey guys, i'm back again after having my 2007 G35x sedan tuned for about 4 & a half months now. The car has been extremely great but i've been having a weird blip in throttle in 3rd gear after the car has been warmed up for about 15-25 minutes. Basically when driving the car it would shift through gears normally then after the 15-25 minutes when in 3rd about to go into 4th gear there would be slight bog or power cut between 2k-2.5K rpm then it would shift into 4th gear. Has anyone ever had this issue & could possibly know what the cause is? I haven't pulled any codes relating to it so my guess would be maybe the trans fluid is dirty or overheating? i pulled the AWD fuse & it was shifting perfectly until i got up on the car a little bit on the highway and downshifted then it started to blip in 3rd again so i'm at a loss rn. i had the valve body rebuilt last year july because i was getting P1757.

 

Whoever tuned your car should have the ability to do data logging. Any codes speed up most repairs..
