Then there's something wrong with your truck. With the torque converter
unlocked, you should have been over 2,000 RPMs with the pedal floored.
Oh, that's right - you've got a DTT converter in there.... probably WAY too
tight for a stock engine. It's not the fault of the truck or it's
transmission - you altered the way it's supposed to perform.
I've heard of this problem with the automatic V10 Dodges too. Can't get the
RPM up enough to pull. My 6 speed 04 and 5 speed 92 will start very heavy
loads. No need to rev up the engine. 5.6 to 1 first gear :)
Strange that Tom has not heard of this. Goes to show ya can't know
Not to mention original owner switched out the read axle gears to 3.73 from
the factory 3.53 or .54??. You would think that extra gear ratio would help
out on such a condition. He made quite a few changes for the purpose of
towing a 5th wheel travel trailer.
You've got it backwards. With 3.73 gears the drive shaft turns 3.73 turns
per turn of the rear wheels. With 3.54 gears, it's 3.54 turns. So it's
harder to turn the shaft. Plus the total drive ratio is the transmission
ratio, times the rear end ratio. So if you have a 3 to 1 ratio in the
transmission and 3.73 rear gears, you have a total ratio of 11.19. That
means the engine turns 11.19 turns for each turn of the rear tire. With 3.54
gears the final ratio would be 10.62. With 4.11 rear gears the final ratio
would be 12.33. The more times the engine turns for each turn of the wheel
the more torque is applied to the wheel.
I think you just contradicted yourself.
More torque means more power being applied thus easier the vehicle can tow.
If the first part of you mention is true, then most 3500 duallys would come
with 3.54 gears rather than 4.11
You can take this with a grain of salt, I overheard a conversation while in
TruckPro the other day. They say Ford dealers have stacks of turbos they're
replacing and the word from Ford is don't idle them and don't let them sit
for two weeks or more without starting them else the varible vanes lock up
and require replacement. FWIW, YMMV.
Is that on the new Fords or on the previous models? If that problem is with
the previous models, that may be why they possibly went with two standard
turbo's of smaller size then the one large variable one.
If at first you don't succeed, you're not cut out for skydiving
