A904 HP rebuild kit
OPT answered all my questions before ordering. Kit arrived fast. Front planetary thrust washer was not included in the kit. Brian sent these and the overhaul is now completed. Excellent before and after customer support. I have 2 more to rebuild and I will source them from OPT.

Brian and the Crew are the best
Long story short is person whom I bought the "rebuilt transmission" from needs to learn how to use a torque wrench. After finding a bolt hanging down from the valve body and one hitting my torque converter, I decided to do my own rebuild. Brian promptly answered question by email and recommended the correct parts. Transmission runs great now.

I ordered the A904 kit and after ordering I realised I required the next up rebuild kit and contacted OPT to see if this order could be upgraded and thanks to Brians help the order was changed and pricing adjusted with out any fuss. Excellent service OPT.
