Well, my T45 has been giving it's death whine for about 4-5 months, now.. It's whining in every gear, except for 4th.. which leads me to believe that it's a coupler bearing. I can spend a couple hundred bucks, and fix it.. or, spend some money to get something stronger. I have a D1SC kit on the way (replacing my old P1SC), and I really want to get this taken care of before I put the D1 on.. My goals is around 450-500whp tops.. (built bottom end going together this fall).. My head is spinning from all of the transmission options out there.. What's a solid, decently priced combination for this power level? I guess I could just pick one.. but, I really only want to do this once.. What do you guys think?
