Have a Komatsu FG30 with torqflow trans. Older style with iron case and aluminum valve body. Nissan 2.5L engine. I believe it's a ST-16. I can get more info later.

Truck came in with no reverse. Found snap ring blown out of clutch pack and was sent in to be rebuilt. Put trans in with new pump, torque convertor, etc.

Now trans fluid spits out of the breather after a few minutes of run time. Fluid level is in the middle of the marks and it is filled with Crown trans fluid. (I believe its Dex III...smells and looks like it at least).

I've heard they had issues with wrong fluids in the past. I also replaced the cooler lines.

Any suggestions? The truck travels fine. The fluid doesn't appear to be aerating. If I pull the dip stick up and release the pressure, the fluid stops flowing out of the breather.

This trucks been here two months while waiting for the trans to be "refurbished". Then found additional problems after repair with brakes, yadda yadda yadda.....customer is mucho **** off o so time is an issue.

Thanks!
