hello, i have 94 4runner with 5vzfe swapped in with my original a340h trans. Engine and its harness is from 98 4runner 4x4 auto. i have same problem with it shifting gears. if i get t100 4x4 A/T ecu and just swap it in there, will it work or i need also to swap the engine harness to ?

Thefallman, Hello i thank you in advance for your time. I'm doing a 3.4l swap into a 94 4runner with an a340h auto. I have a t100 2wd ecu and complete engine harness. I noticed in a post years ago you instructed someone to use the a340f internal wiring harness to continue the use of the factory trans. I know the t100 ecu and a340f neutral safety switch will allow the transmission to shift properly. my question is how to get the 4th solenoid to lock up in the t case to get the 4low to function. again thanks for everything.
