I wish I had been folowing this one earlier. I didn't read it all but yeah, my first thought was the accumulator spring deleted and I'd just about bet my life it has a B&M shift improver kit installed as a stage 2 kit where you'd probably really like the Stage 1 a lot. To late for that though with that plate since it's been drilled for the stage 2. And I don't mean be the bearer of the bad news, but just so you know, when that accumulator spring breaks soon, remember you heard it here first. You DID NOT correct the problem. You put a band aid on it, and it's actually common even in OEM form, or at least has been for me, when opening up Th350's you find that spring is broke and the broke piece is going to eventally curl up into the other piece. Just the way it is. What I read of Nick's posts is correct to the best of my recallection and then some, but not sure he mentioned this about that spring being common to break and with that shift kit beating on it, I think it'll be sooner than later. And yep, the detent cable and modulator are moot issue in this case. It's the dual feeding plate and the drilled holes causing the harsh affect. Maybe some nice spring day you might want to drop the valve body and install an OEM plate and replace the 2 check balls that are deleted. I'd imagine Nick or I could send you a plate and check balls if you need them. JUST FYI, I do not clean used parts when I send them. I don't keep a solvent bath set up full time.
