Q: on 27 aug 2006 155358 -0700 tmills65 mills@brewersmarine.com wrote i am trying to figure out which gear ratio a 96 ram 1500 4x4 has. i know there was only a few options from the factory but this truck is new to me bought used. is there a tag on the diff or something i can look at without popping the rear cover i know if i put the truck on jacks and the tranny in neutral i can figure it out by counting the number of drive shaft rotations it takes to turn the rear wheel on full turn but maybe there is something easier. thanks check your glove box... our 99 ram and 01 dakota both have the gear info on a label in the glove box.. mac https//home.comcast.net/mac.davis https//home.comcast.net/mac.davis/woodstuff.htm .

try removing the thermal switch from the transmission line re-attached electrical connector plug hole in line. i tried a variety of resistors in that circuit that i think bill kondolay from diesel transmission technology suggested & i ended up removing sender installing pick-up for temp gauge & zip-tying sender/wire to frame. that damn computer wanted to see that switch nothing else worked! .

i have been looking around and considering a cold air box since the air boxes on the cummins are restrictive that is what everyone says right. i came across this part that is approximately 4 in diameter and is sold as a modification to the current air box. you cut a 4 hole in the bottom of the current box and the hard plastic tube fits into the hole and the other end is done near the front bumper; thus cold air is rushed into the air box. the company i saw this advertised wanted $129 for this simple modification. well i spent $4 at lowes for a 10 foot 4 diameter piece of tubing that looks exactly like that of the $129 part. i put that in and ran the other end down to the front bumper. not sure if it is improving anything maybe dropping my egts a little but it is too early to tell. next im considering a full flow through muffler but i cant make one of those... bob 2003 r3500 for your muffler you may want to look at genos garage they have a muffler elimination kit avail for the dodge trucks. www.genosgarage.com/products.aspdept=90 -- ---------------------------- -chris 05 ctd 06 liberty crd real trucks dont need spark plugs. thanks for the advice on the elimination kit. did you put one on any results to share bob its next in my list of mods. not done yet. -- ---------------------------- -chris 05 ctd 06 liberty crd real trucks dont need spark plugs. i was reading up on the advantages of changing the muffler out. everyone mentions that it will be louder. i am more concerned with increased performance and fuel mileage. what have you learned thanks bob .

i know this is a subject that has probably been beaten to death here i am new so please forgive me. i have a 92 2500 4x4 with a receintly rebuilt 3 years ago jasper trans. about a year ago we had the od stop working on the highway i pulled over and replaced the throttle position switch had lunch.. and i had od again for about 1/2 hour and it went away again. the transmission to date works fine when cold or till i drive a few miles then i loose the od till she gets cold again. the engine temp gauge never shows hot and i have also just changed the fan clutch. i called jasper who told me it was either a speed sensor or tempature sensor. since i had previously changed the speed sensor and my speedometer is working fine i ruled that out. i have to assume the tempature sensor he refers to is the one attached to the cooling line under the transmission. how can i prove a bad tempature switch i am open to other ideas or tests. guys i would love some help thanks doug crall dcrall@ccjax.com .
