Good morning Don...

Thanks for making me look like an idiot. :-)

You obviously have more knowledge and experience than I do, so I'll take your word for it (and Adrian should too!). But I'm still not sure that I understand. Wouldn't the engine revv higher in a lower gear? E.G., at 25mph in 3rd gear and at the same speed in 2nd, wouldn't the engine be producing more power in 2nd gear, since as you say, the tranny multiplies torque in lower gears? I know that my car will accelerate sluggishly at this speed in 3rd gear, and downshifting produces a better result. Wouldn't the engine be producing less torque in 4/OD, since the engine is turning slower (and the transmission is "over driving" it)? I understand that torque isn't exactly linear, but I also know that this engine produces more torque at around 3000rpm than it does at lower revvs (136lbs@2750rpm). 3000rpm in 4/OD would probably have you rolling in excess of 80mph.

Also, why would the O/D have an affect on the low gears when it's locked out of everything but 4th?? Does this have something to do with the "sprague" gear that has been mentioned on the BB?

Thanks for helping an amateur understand.... :-)
