i would say wheel bearing on the way out??
or you have a suspension bush going.

See may threads on here, you need to deflate the air springs to check for sure

i hope you didn't put oil in the transfer box???
think that's meant to have ATF in it??

But am assuming you refilled like for like though.

unfortunately the OBD is not the most accurate measurement.

You need to use a decent multimeter on the charging points

13.6/7 is OK depending where you measure it!!

ideally you want 14 - 14.2 at the under bonnet charging points as it is a long way to the battery..
And the high charging current will cause a volt drop along that cable.

GM 5L40e does do engine braking.

In all modes as per design..



but the OP has a 6sp ZF as its 2005.

Have you checked the Injectors and injector wiring??

manifold pressure could be fuel rail??

Mine used to be a pig to start when warm due to 2 injectors leaking and it ran pants for a few minutes.

(Apologies if done as not read the whole post)

Its a manifold off job minimum.

Whats the issue?
It could just need a regulator change which can be done in situ.:-

Theorising or Hypothisising...(even if i cant spell any of them!!) When driving forward to the pit the wheels drop into the rollers.

[quote="OverheadG"] If I was to buy a refurbed box and fit it myself; does the gearbox ecu need to be paired with the car in a anyway? Or will it be just plug and play. Also.i can confirm, yes it is the 5spd GM Gearbox [/quote] Plug and play You may need to reset adaptations though so it s...

The trouble is ATF and engine oil don't mix very well!!
You will need to flush it out and that will be a pain, and you won't get it all out unless you have a mega flush done

Then there will still be remnants in the torque converter.

Strip might be your best bet..

Ignition barrel is also a contender.

And look who comes out the woodwork.... That looks right manky (tech term) and is definitely not right. Is it thick n sludgy?? ATF for these should be straw or red and feels quite thin Smell it for burning too. You could rebuild it yourself and is not that difficult really. I had mine apart enough t...
