the sonnax line booster is sick! first gear not too noticable but second is beautiful and third/fourth alike. took me 10 seconds to do as well. definately worth it. 30 bucks for a smile and extending the life of your tranny? a must have!

i also changed my plugs, spark plug wires, filter, and got the 02 sensor gap things and am back to around 20-22 mpgs although nobody believes me. now with my 140lb sub/box itll never be the same

 

cool. i would buy one but i hate buying things that i could make myself for 1/3 the price...
plug and play would be nice tho

 

ok fill me in what is this contraption ?? and 20+mpg LMAO

 

your overhead is wrong lol!

whered you get a sonnax for $30? link please

 

i still want to know WTF it is

 

well all i had to do to confirm my choice of making it or buying it was reading about that guy blowing his tranny or whatever it was, getting all those codes, and i decided to buy the harness. but it simply increases line pressure 15%-30% psi to the tranny which means firmer shifts, higher torque capacity, and increased clutch holding power. haven't taken it on the highway buy its definately something im excited for now

 

it aint my overhead! ive calculated it many times. not saying fuel efficient, but it gets there, not my loss!

 

LINK!!!!!!!!!to this contraption damm its like pullin teeth ??

 

yea link please, I only saw them for $50. IF your truck actually got that good of mileage you should seriously contact dodge so they examine what they did right on your engine so they can fix the rest of ours, including the new fuel efficient hemis.
