yeah i had a leak the other day coming from shift lever and from rear seal, changed rear seal then took off the four bolts that bolt down the shifter. took it off applied some silicone reinstalled it , put it all back together, now it wont shift into 5th or reverse. took it apart and wiggled it just wont go in, all the other gears work good. so i put it back together and drove it home. has any one have a problem like this before.
WTF im stumped

---AutoMerged DoublePost---

just a note never had a problem with this thing everything worked good, until i took off shift lever. when it s opened up it seems like its jammed for some reason , the other gears work ok. i guess im going to do the unthinkable have to take it off and open it up, man o man why couldnt they have a big cover like the older trucks used to so a guy can access the tranny .

 

 

Sounds like the fifth gear nut fell off

 

where is the access for that from the front or back of tranny. do u have a pic
thanks. now i have something to look for, if it is that, should i put lock tight in there. also ive been using lucas 15- 75 gear oil synthetic , the guys down at this trnny shop said use only chrysler syntec oil, whats the beef no way there oil is better than others, never heard this before.

 

ya sounds like yer 5th gear nut fell off...............pull rear driveline and transfer case then the tail housing off the nv4500 and put it back on................then when ya get home get a new nut and 5th gear and put it on and tack weld it on...........do it to a friends here a year ago and all is well

tack weld 5th gear

sounds like a plan thanks alot.

 

never pulled it off yet to frackin cold up here . my garage is not heated. i found out there is an upgrade kit for $500. i can get. do i have to get the whole kit or is it just a nut and gear needed.

 

Freddy, do NOT use anything other than Castrol Syntorque - you can only get it from Dodge Dealerships (and maybe chevy dealerships as wel). Using anything else will likely eat the fiber synchros and you will be faced with a complete tear down.

In in Etown too, but unfortunately I dont have a big enough garage to fit a full size.

 

find out whats in the kit????

I did one for my friend that was a new gear and nut....the nut had some retention screws in it too and it still came off 2 years later so thats when we did the tack weld

 

well guys had to bit the bullet when i took it apart a piece of a gear fell out. so took it our and off to a tranny shop it went, 5th gear updated mainshaft and reverse . now it runs like a charm
