any place on the block or tranny is fine. closer to your battery ground/chassis ground is best - and away from heat. leave some flex. protect with high-temp split loom. there are usually unused threaded holes to use in the block or housing. i don't use bolts that are used for brackets.

I was told there is no need to do the tranny cause it is grounded through the motor. I'd rather still do the tranny if there is any possible benefit

Hes saying you can use either the engine block or the tranny, not that you have to use both.
