and cause a restriction to oil flow, and change operating pressures

Are you saying an external cooler is a bad idea?

[ratter]

air to oil is not ideal, but a lot less of an issue than the milkshake, PWR seem to be the go

[Mr_4.0]

The zf is a very sensitive box. Any change to pressures or temps can make the box operate worse. You need to really plan out an external cooler install on a zf. I would suggest using a stronger radiator/heat exchanger as well as an external cooler. Run them in series. Do not run the zf solely off the external cooler.

20's all around just wider on the rear. Had them for a couple years and no problems until now

Out of interest what are the full Tyre sizes you have for front and rear? (profile etc).

Did not replace the mechatronics unit as the gearbox seemed to be operating fine. Was driving how it was meant to be and changing when it needed to. The trans place quoted $300 per solenoid and 9 of them in the box therefore totalling $2700.....

the mechatronics unit should have been stripped down and thoroughly cleaned by somebody that knows what they are doing, the water would have gotten into the unit and will cause corrosion on the pistons and bores and will burn the trans out at some stage from the valves sticking
