TJs and JKs
Q: The manual transmission in my 1998 TJ likes to stick. It won’t go into first or second without some forceful help. Any idea what would be causing this? I am looking to sell it to a buddy, so I just want to be honest with him. Also if it needs to be replaced can the newer six-speed tranny fit into the ’98 TJs? I also just purchased a 2012 JK Rubicon in the Dozer color, and would like to know what all has been done to the project JK that you guys are currently building? I want to build up the new one the right way from the beginning. Thanks.
A: Dallas, the NSG370 six-speed tranny is almost a direct swap into your 1998 TJ, but it will still take some massaging. The issue is that the six-speed uses an integral bellhousing that must be modified so the CPS sensor can be repositioned. Or, an aftermarket CPS sensor that mounts to the harmonic balancer can be sourced from Advance Adapters or Hesco. Either way, the CPS sensor needs to be moved so the PCM in your 1998 TJ will accurately recognize the pulse signals it transmits so proper engine timing can be maintained. Concerning your current tranny, it would be difficult to say why the gears are sticking without seeing the unit first hand. Check the fluid color and consistency and inspect for metal shavings. If there is a heavy presence of metal or greatly discolored or sludgy fluid in them, it may merit a rebuild. As for the JK, there are so many cool parts we don’t know where to start. We’ve used quite a few on our projects so far and have not been let down. Check out our website at 4wdmag.com and do a search for Jeep tech articles. There you will find a catalog of all the JK upgrades and builds we have completed to date. Thanks for writing.
We Recommend Seatbelts!
It came to our attention recently (unfortunately after publication) that the driver and passenger in the 1945 Ford GPW featured on the cover of the November 2011 issue weren’t wearing seatbelts. Please know that we strongly recommend wearing seatbelts while operating or riding in any 4x4. While the vehicle featured was equipped with aftermarket seatbelts, it was the decision of the driver and passenger to not wear them.
