2020 Chevy Express 2500 RWD 4.3 V6 8 Speed automatic transmission fluid level check procedure.
The 8 speed uses DEXHP.
10 Speed uses DEXULV.
It's not hard to do. Just pretend it is a modern Volkswagen automatic, only easy to fill.
This is a used (20K) transmission (8-Speed,) going into a new Chevy Express with 100K on the odometer. The transmission fluid cooler was flushed, and the filter was changed.
There is currently no information available on this service.
When the actual temp. specs. are available I will post them.
Traditionally you would use the transmission temp sensor parameter ID or (PID) on a scan tool to check when it is time to check fluid level.
The back of the hand method has worked for decades now. If you don't have a capable scan tool, then, "This is the way."
