com_mako Posted February 5, 2011 Share Posted February 5, 2011 the transmission will shift a little bit at higher RPM it is like a towing mode on comfort, it will shift at normal RPM so better.. :nuts: fuel economy Link to comment Share on other sites More sharing options...

87Warrior Posted February 5, 2011 Share Posted February 5, 2011 As I understand it (could be wrong) the later models do not have the switch and thus the TCU was defaulted to the 'power' setting. Link to comment Share on other sites More sharing options...

com_mako Posted February 5, 2011 Share Posted February 5, 2011 since the 87-90 era has the renix system and later 91+ has OBD system, the TCU may adapt to the engine/trans load the renix system was more a basic electronic no brain system, so you choose power or normal shifting this is how I understand that switch Link to comment Share on other sites More sharing options...

Contrary to popular myth the deletion of the power/comfort switch had absoluetely nothing to do with Renix vs OBD1. The switch carried over into the '91 model year and possibly the '92 year. (My '91 had one my '93 didn't). Link to comment Share on other sites More sharing options...
Automan2164 Posted February 15, 2011 Share Posted February 15, 2011 End year for this is '92. My '91 Eliminator had it, my '92 Eliminator does not. The story that I have gotten from old Jeep Techs and tinkerers is that the "Comfort" setting allowed for softer shift points, which make the clutch packs slip a bit more, which made the friction discs not last as long. As well as bad fuel mileage since the clutch packs were slipping more than usual... So in '92 they decided to stick to the firm shifted, better mileage Power option, and hard wired it in. Rob L.

Pete M Posted February 15, 2011 Share Posted February 15, 2011 power setting = normal comfort setting = why on earth does this even exist in the world? :dunno: It's right up there with the CAD and the Dana 35. not Jeep's finest moments. Link to comment Share on other sites More sharing options...
btm24 Posted February 15, 2011 Share Posted February 15, 2011 well now I feel dumb Ive kept mine on "comfort" since I bought the truck :fool: thanks rob for that info ill put it on power tomarrow. Brandon Link to comment Share on other sites More sharing options...

Never bothered putting it in when I originally put the AW4 in years ago but I threw it in when I did the re-wiring this spring. Really, really glad I did. It stayed in "power" until the first time I tried driving on snow covered roads in 2wd :eek: Helps out quite abit to be able to lug it down a bit more on the hills. I'm actually finding the combination of the lower bottom end torque of the HO motor and being able to rev it lower a bit better in the snow.

jimoshel Posted February 15, 2011 Share Posted February 15, 2011 I never used the power-comfort switch until the other day while driving into town. When I switched to comfort a soft pillow popped from the head rest behind my neck, two hands came out of no where and began giving me a massage and a hot toddy appeared in the cup holder. Only in a Jeep. :rotfl2: Link to comment Share on other sites More sharing options...
SW86 Posted February 15, 2011 Share Posted February 15, 2011 i usually leave mine on power but i can tell the difference when its on comfort and i don't like it at all. its more sluggish. Link to comment Share on other sites More sharing options...
Eagle Posted February 15, 2011 Share Posted February 15, 2011 i don't think mine works i fliped it on in the snoe there was now dif in the power i had It doesn't affect the engine, so it can't produce more (or less) power. ALL it does is change the shift points, and make the tranny engage the gears more softly (which, as noted, equates to more slippage and more wear on the bands).
