hey All,
i would appreciate your assistance resolving this issue, the haltech 2500T is controlling the A340e 2jzgte transmission, i have recently wired in a line pressure sensor, also changed the wires entering the valve body using the a650 valvebody wire harness inorder to have an internal temp sensor. upon test driving , gears 1,2 ,3 shift successfully however when shift to 4th gear its going into neutral. Is this a software or hardware issue? Any advice on resolving would be most appreciated.
thanks
Is it showing it's in neutral, or are you just losing drive? If the latter, it may be a gearbox fault?
Gord thanks for the reply , I am losing drive. however , the transmission is working perfectly shifting the gears manually with the valvebody disconnected.
Is there an option to reset the transmission map on the haltech, and restart from scratch without losing the rest of the tuning data?
How have you configured the Torque Converter lockup?
