5th gear
#21
You have 4.10's in that truck? If so, then you may not be abusing the transmission after all. I thought you were lugging it based on something you said in an earlier post. The definition of lugging it as far as I've always heard for these transmissions is applying heavy throttle at or below about 1500 rpm. If you have 3.54's and can't get more than 45 or 50 mph out of 4th, what rpm is that?

yep all the other gears work as usual. it goes into 5th's place in the shift pattern, but no power transfer. how do i go about replacin the counter shaft? am i better off sendin my trans for a core n buyin a new one? i am fairly mechanically inclined and have a heated garage to work in. is this something i can do?

check the cone gear on the countershaft, it is on the back of the transmission the bigger gear on the lower shaft. just take the snapring off the lower shaft and check the internal splines on the gear. i had the same problem with my 96 and thought it was the famous nut but mine actually ripped the internal teeth on the cone gear. if thats the case, call Southern Gear Co. out of georgia. dodge wanted $400 for the gear and i got a new one shipped to me for less than 60 bucks from southern gear. their number is 1-800-289-7432. p.s. the splines will look ok from the outside but under the snap ring is a different story!

this was exactly what the problem was. i pulled the snap ring off n pulled the gear and there are no teeth left inside it. the countershaft is fine but the gear is toast. i had the shift tower off the tranny lookin down inside thinkin this is not gonna be fun. thanks again man u saved me alot of hassle
