Hello everyone, the transmission on my 94 WRX is struggling to shift into 4th gear so it is time to find a new transmission. From my understanding, the gear ratio is 4.11 and the code is TZ102YB3AA. I have found a transmission from a 02-05 WRX EJ205 with code TV1B4YB1AB and It has the same gear ratio and it is the same drive system (VTD). Will the transmission be plug and play or are there other things that I may be missing? thank you very much!
