Yea, I'm starting to run a slight fever just thinking about those old transaxles. Paired up with a 2.0 Peugot you could possibly have the "most expensive to repair forklift" in the world!! Remember the SAMS valves that couldn't be disassembled and cleaned? Best filter in the world!!
omg i remember those trucks, only did two transmissions, complete rebuilds, not a nice one to work on.yes the updated relief was available, but now, dont think. had a vc60d in the shop last week, its gone
Sounds to me like what you have is the updated relief valve. Years ago these units had a problem with transmission filters starting to leak due to pressure spikes. There was an updated relief valve Cat (Daewoo) had us install. The relief valve is inside the gerotor housing. You access it from the bottom.
Lift up the floor plate and the solenoids should be on top of the transmission, they should unscrew by hand and slide off.
