Hey guys new here but at my witts end with my car and really looking for some help. Time for a long story. Owned my r34 NA Auto for about 9 years now. Car was running well until about 4 years ago when I started to get the A/T limp mode whenever the car went to shift into 3rd gear. Wasn't to fussed at the time as the car was about to go into the shop for a full motor and gearbox build. Car ended up with a full forged motor with turbo and all the bells and whistles which I haven't had a problem with. Gearbox was also completely rebuilt from front to back and absolutely everything is brand new. Car is running a haltech 2500 elite if that helps. Now to the pain. After all the money and things replaced it still has the same AT problem when it tries to shift to 3rd and it just sticks on 3rd gear limp mode from there on out. Car has always been and is still auto. It has the original box and motor in the car and me and my mechanic can not figure out why the hell it keeps happening. My next move is replacing the TCU module as it's separate in the GT model but other than that I'm lost Any ideas or help would be much appreciated Picture just coz I like to show it off. Thank you guys

Just want it all good and ready for my first tune as never had one what should I get done in the tune and what boost 5? And just get fuel/air and some timing pulled/retard etc...also haven't tried yet as my new turbo is on its way but the one I was using was blowing smoke and whining and no matter what it was stuck on 7-8 psi my hand controller wouldn't turn it down so waste gate? Over boost could've been the problem?
