Auto vs. Manual Transmission Question
 

Someone who understands the operation of the Torque converter answer a
question for me. Take a Jeep with a 4.0l. This jeep has 5.38 gears and a
2.72 transfer case (231 or 242). If you have a AX-15 5-speed with a 3.8 1st
gear ratio and a 42re 4-speed automatic with a 2.7 1st gear, you can do the
math and by numeric value the AX-15 has the better crawl. But here is my
question....Does the torque converter come into play so that you are
effectively getting a decent crawl with the automatic even though the manual
has the lower first gear? Pardon my ignorance.

Re: Auto vs. Manual Transmission Question
 

You will have an unusual setup with those 5.38 gears (normally reserved for
the 4 bangers!)... but as I understand the automatic gives you a virtual low
gear... only as fast as the skinny pedal makes it.
BTW there is no excuse for your ignorance!

Most torque converters slip at about a two to one reduction, that's
what gives the Cherokee automatic the five thousand pound tow rating
over the stick two.

You said "You will have an unusual setup with those 5.38 gears"
That tells me he took the Dana 44s from a Real Jeep.
