Towing the HQ?

[Innuendo]

Not sure why that link says 2004 only for 4L65E for Crewman and tonner. Must mean 2004 onwards.

The claim appears to be that all but 2004 models used a 4L60-E and not a 4L65-E it is certainly not onwards as early VE V6 still use the 4L60-E.
Later they would switch to 5L40-E (5 Speed) and 6L50-E (Six Speed) and the 6L80-E for the V8. Or so it reads!

i towed a dirty big car trailer loaded with a WB ute using a VS Comm v6 auto ute. It never was the same after that!

I know 2005 got the 4L65E in V8 tonners and Crewman, and I was almost certain the V6 was the same. I reckon that 2003 Crewman and tonner got the 4L60 but 2004 onwards got 4L65E. The wiki page has multiple other errors/omissions on it and this is probably another.
