4+3 reverse lift-up ring question
I've just replaced the reverse lockout rod in my '85 and when I shift into reverse the lift-up ring stays "up" whereas before I believe it returned to the "down" position. How does it work on your 4+3?
Many thanks!
John

Thanks powerpigz-51 and VB Racing.
Mine has the spring. What I'm asking is in all other gears the reverse ring goes "down" against the stop on shaft but in reverse after pulling the ring "up" to get into reverse, the ring stays "up" and won't go "down" until moved out of reverse. Is that how yours works?

Doug Nash was a dragster designer/driver in the 50's and 60's (the "Bronco Buster"). He built a 5 speed transmission for dragsters that was very popular and then came up with the idea of adding an overdrive unit behind the original 4 speed in Jeeps that would add overdrive to the top three gears ("4+3"), a total of seven gears, very useful (and popular) with off-roaders.
When GM designed the C4 in the late '70's/early '80's they were scared to death of having to pay the Gas Guzzler Tax passed in 1978 during the first oil shortage. Somehow GM engineers heard about Nash's 4+3, went to the Doug Nash facilities, test drove a jeep with a 4+3, realized it 1) increased the car's gas mileage and eliminated their Gas Guzzler Tax worries, 2) increased the car's top speed and 3) did both at nominal cost so they placed their order.

4+3
I'm having a problem where I have to disconnect the reverse linkage from the transmission it feels like the shifter itself is being stuck in the reverse position even though you can still put it in all four forward gears if somebody would like to call me let me know thank you

There is a procedure for setting neutral on the shifter. Not a lot of fun but simple enough, just takes time. With the wear of years I bet yours is in need of re-alignment. I will have to copy it from my manual.
Sure helped my shifter after I adjusted it.
