will a 1jz a340 bolt on to a 7mgte?

[jmillan]

i baught a 1jz auto tranny bc my tranny has no reverse anymore and i want to know if i can swap it out with this 1jz tranny just like that.

 

[hvyman]

Bell housings are different.

 

[jmillan]

thank you hvyman for replying, will the torque converter bolt up to the flex plate with out modifications?

 

[hvyman]

Not too sure on the specifics but you could always use the one thats on the car now.

 

[tlo86]

what engine is on the car?

 

[hvyman]

7mgte. It's in the title.

 

[tlo86]

haha whoops , swap the bellhousings. *sometimes* you need to swap the extension housing as the speedo gear is a little different. ive had '1jz' autos come from all sorts of cars so you never really know

 

[jmillan]

damn i dropped the tranny in class and the sensors were different also the throttle link cable is non existant on the 1 jz a340, will that be an issue when driving?

 

[hvyman]

What 1jz engine did it come with Vvti or non?

 

[jmillan]

hvyman vvti have you done any tranny swaps of these sorts?

 

[hvyman]

No I only drive manual trans cars.

But the newer Vvti engine uses a drive by wire throttle body thus it would not have a kick down cable. That one might not be totally compatable.

If it has the same speedo might be able to switch some sensor but you won't be able to down shift.

 

[tlo86]

he wont be able to get it to work without an aftermarket trans controller

 

[jmillan]

Ugggggg!!!! Then I guess I have an A341 for sale in Oceanside ca LOL

You won't be able to swap extension housing also and will need a custom driveshaft.
Tlo86 is true, Line pressure is controlled by a solenoid with a PWM signal so you need a standalone, and But, you may swap valve bodies to keep your original Trans controller and kick down câble (which in fact is a line pressure control cable).

You won't be able to use 1J torque converter.

Finally, the whole swap will only offer you stronger clutch pack (more discs)

Rollus thank you so much for that use full info i managed to swap out the valve bodies to the a341 also i did manage to swap out the tail the only thin i did have to change off of the a341 is the magnetic ring for the speedometer with the one off the a340. also the flex plate had the same bolt pattern as the 1jz a340 torque converter, BUT my car stalled after driving it around and it made a back firing noise followed by a loud bang, now when i try to turn it on it makes that lous bang in the engine, any ideas?
