Possible trans issue

[Greggles_VS]

Wondering if its normal for my transmission to go into 2nd gear on its own when i have the shifter all the way down into first?

yes, after XX kmh it will automatically upshift into 2nd

yep, computer takes over. you can have it adjusted in the tune though.

Presuming your car is more worked lol, mine changes at 6250rpm at 65kmph

7hdd is just a 1997 4l60e, essentially the same guts as a vn th700 except for the valve body and main transmission casing and electronically controlled, over the years gm changed a few minor internal components, 2-4 servo, boost valve, pretty much anything from a vn to newer model commodores with a 4 speed auto is basically the same main driving internals with a few minor modifications as they ironed out the bugs. For a daily driver they're a good trans.
