It only specifies it for initial fill.
That's the same as running break in oil in a new old motor.
That does in no way mean anything else will cause issues. This is why there's standards....

The only reason manufacturer is saying only to use the oem oil is to cover their backside. I'm amazed they even responded to that at all. It's a stupid question and there's only one way they could answer it.
If it was CRUCIAL to use tq95, then everyone with a btr would, and they wouldn't can it. At least not without a working alternative.
The best atf for a 4sp auto is whatever is on special.
In fact, if there's a problem or it's worn out, the best thing is actually the oil still in it.

Good link on the service bulletin though.
