ok everyone i have a auto 1jzgte but i kept the 2jzge trans. Reason i did this is because i had and engine set out of a supra. Regardless my problem is that my ge trans shifts way too early. It shifts at about 3500rpms. Shouldnt the 1jz shift at like 7250? What could be my problem?

 

What ECU are you using?

 

using the soarer ecu,,,also quick question is there a cable that goes from the throttle to the trans?

 

is your kick down cable connected or is there even one there? yes theres supposed to be a cable from the trans to the throttle body so it senses what kind of load is on the engine to tell the trans if its at wide open throttle or just cruising...

 

^^ that cable is for line pressure, not a kick down cable.
