1jz auto gearbox shudder

[pete05]

Hey all ever since i have done my conversion my 1j auto has had a shudder on inital take off, once your driving its fine only on take off, also the more load you put on the car i.e towing a trailer, the worse it gets. i have done a serivce to the box with type 4 fluid and its no different.

have you checked your tailshaft inclination angle .
if your tailshaft is on a weird angle you will get a vibration on takeoff and it shakes the whole body of the car .
Also check your unijoints because a tight one can also cause this problem

my MZ12 shudders a little but i pretty sure its the rear suspension. it drops in the ass end, then tramps a little.

kinda feels like shuddering

the MX73 has the same rear suspension so it probably behaves like mine

Probably S1 shift solenoid starting to go. Check for ECU codes. Code 62 will confirm it.
