Truck came in with a leak from the "air control module" K3245 on an Eaton Fuller FRO 16210C transmisson.
Driver went and bought a replacement but alas, as truck aired up, the leak started from the same "brand" new module.
Has anyone had any expierence with this type of issue?
This particular module is on top of the transmission on a 1999 Volvo VNL.

Another mechanic advised that it "could" be the selector on the top of the shifter.

sometimes water gets into the cylinder for the range selector in the top cover. it corrodes in there and the piston cant move, so the air just leaks out. it could progress to the point that eventually you wont have low range anymore.

Check the range piston on the back of the trans.

FRO transmission range selector is located inside the transmission under the top cover.they're well known to leak.easy fix,low cost around 40.00 for rebuilt kit.also check the o-rings under the air module.

i just started hearing a hissing in my shifter, right at the handle
so it may be that i need to disassemble the handle and replace some bushings?
where do i get the new parts from?
