Interesting thoughts and observations on OD transmissions

One unfortunate thing about the OD Torqueflites is that 2nd over and 3rd under amount to approximately the same ratio

Thats was for Del…. 2nd over and 3rd under ?

Lockup drops about 300 rpms.
One big thing about using lockup besides it’s obvious no slip connection to the trans is that it eliminates the heat generated by the converter.
That 300 rpm slippage creates heat in the fluid.

300 makes more of difference than one would think . My car turns about 3k at 80 . 2700 would be much better .
