1984 Jeep CJ7, Gear shifting / Linkage problem

In a 1984 Jeep CJ7, Shifting into third gear, the linkage is sticking, or not going into gear at all. The gear shift lever has been replaced which has considerably lessened the issue but the issue remains nonetheless. To ''unstick'' 3rd gear, I found a swift (but definately NOT hard, this has to be done in a diagonal shift and NOT the standard H formation to unstick it) shift back towards second gear releases 3rd gear but nothing else will. When the shifter is in the 3rd gear position, at times it isn't actually in gear and a quick ''slam'' back into third puts it back in gear and allows continued shifting.

Likely the shift rails are worn inside the trans. In changing shift, you have removed the wear on the end of the stick, but not the corresponding wear where the stick fits into. It will need to be taken apart to repair this. (would not hurt to have synchros replaced at the same time.) OR, replace transmission if you have an inexpensive one available.

I am looking for recommendations for someone in Chicago who is expert with the '84 Jeep CJs. I have an '84 CJ7 and the linkage seems to be shot, making it very difficult to shift into gear. Once it gets...


not true, at all , any ASE mech can do this.... sorry, its a fact.
the linkage (A/T or M/T , 4wd lever or main gear shift lever>???)
try hard to say , exact what part is bad.
Clutch
A/T box
4WD, issues, ( on my 5th jeep, and have 2 now) Can fix any car.

if i was there, id have you, show me what to do , to get the failed
symptoms. you;d say, sit here, and grab , this? what is this.
the manual stick shift, and id , push in the clutch.
and id see , the clutch works but the shifter parts (bushings) are shot
and the lever flops about,,,, so i pull it down and rebush it with factory parts.
or ,if an A/T id sit there, and put it in Drive, the car dont move
i then try all other gears, L 2, R , do they fail too???
i make sure the linkage shifts correct at the actual tranny.
if not the linkage is bad (loose) or needs adjustment , (FSM covers ways and spec)
like that.
no mech needs to know jeeps. not at all, there is nothing magic here.
"like French cars"
you only need to know 4wd cars. both A./T and M/T

do post back with car spec. with options. we dont know. that.
cant see it.
if your car is not stock, then sure , any mech, will have trouble.
frankejeeps or fanken cars of any kind, are a big problem.
there is no limits to the frank (hacks) is why,
done many,
many shops will look and see all the hacks and not even touch it
for good reasons (many, ask)

Loose stick shift


I've experienced this on a Volvo and it was the linkage bushings. Stiffened it up nice!

Gear stick will not move from park !


Make sure you car is actually in PARK, Easy to do, Just disengage the parking brake (emergency brake) and attempt to push your car both forward and reverse to ensure your car isnt in neutral. If you cant budge the vehicle your good to go! If it rolls forward it may be in neutral or a forward gear. if it rolls backwards it may be in neutral or reverse. If it rolls both directions its in neutral. On that note if it moves at all skip to the third step (***) and make sure the transmissions shift bracket is in the park possition. Depending on your cars transmission model the parking gear is located all the way left to the farthest possition or all the way right to the farthest possition) One direction will put you in Park, the other in will put you in 1st gear, If your in 1st gear the linkage should be too far away from the shift plate to connect if your column says you are in park. DO NOT ATTEMPT TO START YOUR CAR WHILE IT IS IN A DRIVE GEAR AND THE LINKAGE IS DISCONNECTED IF YOU ARE ABLE TO START YOUR CAR IN ITS CURRENT STATE DO NOT MOVE THE TRANSMISSIONS SHIFT BRACKET UNTIL LATER IN THIS INSTRUCTIONAL!!!!!

* Floor shift automatic, the push pin lever (located inside your shifter/gear stick) may be malfunctioning. You have to pop the grip off and inspect the white plastic pin inside the shaft to see if it is damaged, also check inside the grip while you press the safety release (shift lock button) to ensure the internal slide mechanics are propperly working). Also check for anything obstructing the levers movement inside the floor housing.

** Column Shift. Make sure your pull pin lock is working properly (disengages the shift lock when you pull back the gear shift before you select a gear) if its broke theres two possible behaviors you'll experiance -1. You cant pull the gear shift back at all or -2. No effort or less than normal effot is required to pull back the gear shift. If all that checks out then you have to inspect the steering column linkage bar (you may have to remove some of the steering column housing to view it. Make sure the bar isn't bent or that its movement isnt obstructed.

***Automatic Transmission Linkage Check - Look under the kick panel located above the gas and brake pedals.........Once linkage is located under the dash (kick panel) disconnect it and try the gear shift. If the cable moves under the dash then reconnect it and move on to the next step.
Now block the wheels and climb under the car and disconnect the linkage from the transmission and have someone work the gear shift while you see if the cable is operating propperly, if the linkage moves (as it should) then try shifting the transmission back and fourth by hand while the linkage is disconnected., If the shift bracket feels stiff or is dirty clean it off with non corosive chemicals so you dont damage any seals. If the bracket operates smoother go ahead and reconnect the linkage and try shifting with the column again. Be sure to move the shift bracket back to the park position and make sure your shifter column is in park as well before you reconnect the linkage, if you dont you are sure to run into more issues.

Hope this helps you out! If all the mentioned area's above are in working order then your problem is with the car's transmission and you should take it to a speciallist.

Our Isuzu Fuego LS 4x2 Manual Transmission doesn't move even the shift stick is already palced in First Gear, even in second gear and third gear and fifth gear also no reverse, to sum up only 4th gear will...


you may have a shaft key broken in the transmission. 4th is usually 1-1 drive and does not need the key. before removing the transmission, check to make sure the linkage is OK by shifting gears at the transmission. If you can get other gears at the transmission, then the problem is the shifter.

sounds like the linkage is misaligned, vw makes an alignment tool just 4 this problem. mine used to go into the wrong gear, and then I lost reverse I got so pissed off I slammed the shifter to the left and that fixed it, but I cant really recommend that you do this. Best of luck though!

1984 CJ7 stuck in reverse. Staight 6, 5 speed and will not shift out of reverse.


you have a bent shift fork or shaft, you will need to remove the dust boot pull the shift snap ring it the shifter is in the floor and pull the shifter stick off then remove the transmisson top cover and replace the reverse first shift fork, this is the most common cause, if it has a columm shifter then disconnet the shifter lever and try shifting if it shifts then you have bent linkage and will need to figure out where it is located.

Transmision Shifting Problem


Was the fluid you drained red or black? did it smell like trans or gear oil? With linkage disconnected, could you put trans in park by moving the lever on the side of the unit? Oil condition is likely a separate issue...most "blown" transmissions generally have normal operation of shift, it just dosen't do what you tell it to. two things likely going on are: linkage problem and likely in need of fluid/filter change.
