Recently got my transmission rebuilt by pure. But my car is still giving me a really hard time for the 1st-2nd gear shift.
What’s weird is that it’s only a rough shift if I’m flooring it. However, if I let off of the throttle right before the shift, it’s buttery smooth.
If my accelerate too slow on the other hand, it’s an extremely delayed shift.

I’m also getting this Transfer Box code which I have no idea about. I don’t know if it’s related to the weird behaviors I’m having.

If you don’t mind which build did you go with from pure?

What help did they offer for your situation?

I’ll be following closely as im trying to eventually go that route when my transmissions starts to slip or the oil is due for service.

Hoping you can get answers for this!

Try posting this in the main B58/ Turbo Engine/ Drivetrian/ Exhaust Modification forum as well. May get a quicker answer or solution.
