I'd be happy to - though there are some big updates going on for that one. I've been 'meaning' to do it for some time, and have about 90% of the writing done, but I haven't got all the pics I want. The 'final' version of this contains the basic mod, but it also details all the stuff to do (which is easy to do mind you) to incorporate most of the ford internals. I was hoping to take pics of a trans I was going to put together for the 13s for $1300 that another mopar guy was entering, but he ended up having massive flooding back then so the thing is on hold.

To get back on topic (sorta) - David - the tricked up auto will actually INCREASE the rpm drop on upshifts. If it grabs hard it yanks the motor right down to the lower rpm. IF it slips a little the motor isn't pulled down to as low an rpm and it will increase the roadspeed (to some small extent) as it 'grabs' fully. A bit like how if you don't let the clutch pedal up quickly on an upshift, and increase the throttle/accelerator pedal input, the motor will flare up, or not be yanked down as low, not the reverse of that.

D are you sure it was a bw35? For some reason I had it in my head that it 'was' a bw auto, but something earlier - possibly even a 2 speed that went in some early datsuns, but I know nothing of it in terms of design, spec, parts interchangeability etc.
