This is the first I heard of and was very surprised at the Hemi rpms drop way down and the engine seamed to bog down during that 1st to 2nd shift. Does this happen when running at WOT or does it happen at partial throttle?
Perhaps the tranny engineers need to rethink the gear spacing since a 6 speed should have very small incremental gear changes.
Again... Enjoyed the videos and the tests by both members... Good job! :B
First - thanks.
Next, that only happens during the WOT runs. Under partial throttle, you never notice it. I'm surprised it wasn't brought up in the 3/4 ton gas comparison Pickuptrucks.com did as it is a common mention among 6.4L Hemi owners.
The 66RFE has the exact same ratios (and most internals besides the tq converter AFAIK) as the 68RFE used behind the 6.7L Cummins.
It goes from 3.23 (1st) to 1.84 (2nd) IIRC.
