Turbo 400 Transmission

[Lextreme II]

Besides the bellhousing what else do I need to make it work. I am thinking about upgrading to a heavy duty 400 tranny. This tranny can be build to hold 1,500 hp for about $1,500. Best bang for the buck tranny for sure....

You will need the usual rebuild and prep work.


What about one of these too ?:

I got a setup where you can use a stock auto bellhousing to adopt a th400 to a 1uz.

Adapting the trans to the engine is the easy part. Any fool can do that.

What you need to consider is the torque converter needs to adapt to the 1UZ flexplate and the nose of the converter needs to fit inside the 1UZ crank, plus it all needs to be spaced just right. In amongst all that the torque converter must be llowed to move fore an aft with revs. Hence the need for a FLEX plate.

This is not a simple problem.

The tolerance you work with, with an auto is 10thou. That's 0.250mm for the metrically inclined. A conventinal clutch will survive this tolerance but any more and your auto will die.

Think a lot before embarking on the project as I'm well into mine and it gets tougher by the day.

The 1uz flexplate will work with a th400 converter made to work with a 2jz flexplate with very minor modification to the 1uz flexplate. Everything else lines up just right.

Better yet, th400 converters for the 1uz flexplate are available from Supercar Tuning Center 847-640-7305 if you use their bellhousing adapter plate.
