Re: Auto vs. Manual Transmission Question
The short answer is "yes". You can get good torque through a torque
converter even at 0 mph. The fact that you can effectively run your engine
rpm up a little bit gives you the same advantage as lower gearing... to a
point.

Your flip definition is the same as my "Clock". The Dana 300 is
normally in the four o'clock position stock, but can be clocked to the
eight o'clock position for your application, or any other position that
you drill holes at: http://www.4x4wire.com/jeep/tech/xfer/tindex/ or the

Re: Auto vs. Manual Transmission Question
The Crawl Ratio is a number that says how slow you can go without fear of
stalling. An automatic can not stall, therefore in has an infinite Crawl
Ratio. You can twist the motor out of an automatic equipped Jeep with very
low gearing and a very high crawl ratio because the brakes may not be able
to overpower the engine. I have heard of some drivers with autos that must
shift into N when they actually want to stop.

Re: Auto vs. Manual Transmission Question
We are talking about the same thing bill. So my statement about expense
comes into play. Maybe the 300 after I explode the 242.
