Loose shifter in 1986 Jeep CJ7

I have a 1986 Jeep CJ7. How do I tell whether I have the T5 transmission, and if so does anybody have a schematic (blow-up picture) of how these parts attach at the end of the shifter handle.

I notice from reading a few of these repair threads that the fix for a T5 transmission includes, either or all of:
1) Shift Rod Bushing, part # - J3241481,
2) Shift Handle Isolator Clip, part # - J3241239, and/or
3) The ball at the bottom of the shifter assembly. If its worn (or worn away), the shifter will continue to rock around while driving and have slack in it.

I have done some dis-assembly, and reviewed Quadratec's Borg-Warner T5 Transmission schematics, so if in fact I have the T5 transmission, I note that the Isolator Clip which consists of four separate prongs, looks stressed/old, and the tip of one end has broken off. So, I definitely need a new one.

Where the nub comes out of the Shifter Boot (the base to the transmission the shift handle sits on, with the Isolator Clip inside the housing) I notice the shift handle is sloppy with that particular Isolator Clip in there. I then took the nub in my hand (tranny in neutral) and tried moving the nub about, but there's not too much play if any, so I'm thinking the Shift Rod Bushing (the round plastic piece) appears pretty solid, and that the source the sloppiness is in the Isolator Clip. Would you agree?

And, looking at the schematic for the T5, what would the Shifter Isolator be? Does it form part of the Isolator Clip, or is it a separate piece as the description says it's for vehicles T5 Transmissions or NP231 Transfer Case? So, my question is, does this form part of the Isolator Clip, or what is the situation with this Shifter Isolator?

Thanks Medic. Appreciate the help. Been around, but not done much, but looking only, hopefully, to just replace worn parts.

Thanks for the schematic. Was looking at it when I took my shifter handle out the other day. I recognize the Isolator Clip; part 48b. I don't however recognize the Isolator; part 48c. Any idea if I need 48c, and does it fit inside 48b?

After taking off my Shifter Handle, every thing coming out of the transmission and down seems firm/solid. That's why I'm thinking/hoping it's just the Isolator Clip.

Thanks for the on-line manual, great resource, but it only has help for an Automatic Transmission.

Thanks Medic. I will do.

I've got a 5-speed, so it's got to be a T-5.

Yes sir, I did.
___________________________________________________________________

Off topic, do you know whether this vehicle would have a Limited Slip Differential? I have another issue where when turning right the other day, I got this loud rotational sound from underneath, which made me pull over immediately and I stopped for a few seconds then proceeded. Along with this, I've noted a bit of chatter when pulling away from a light/stop, which led me to believe clutch, but the Clutch guy who replaced the clutch a couple of years ago said sounds like rear-end issue. So, a mechanic friend (taught mechanics at high school) asked whether I had a Limited Slip Differential, thinking this may be it? Wonder if I can GOOGLE my VIN, although it was an AMC when born. Whether related or not, have a little oil leaking behind the plate on driver side rear (rear seal).

Hope that's not too much to swallow.

Just to start off, probably gonna have to be patient as I'm not always able to get on line, and am not a mechanic, but like to try do as much as I can. Not a lot of tools, or access to them. I have a couple buddies, one who taught mechanics at high school, another who is a mechanic but isn't practicing regularly. And I can't really bug them too much, although I try to throw things at them.

OK, to the issue at hand. I scraped off the crap and noted a "B" on what looks like a drain plug? On the Right Side of the Differential housing.

Re: your troubleshooting above, I note when I read one of your posts where you were helping somebody else out, I did note you asking about noise when the Clutch is depressed, and I do note a louder whirring noise when I depress my clutch, quieter when foot off. Issues here possibly? Throw out bearing, and would that be a possibility causing issues?

Another thing I noted which may be of interest. Although it is only occasional, is that when I'm driving along, there's a noted lull where I seem to lose power, or the engine wants to give out. Like it bogs down just for a few seconds. Not sure whether this would be related, or whether I'm in need of getting timing set as I notice after my fix last year, I get a bit of tapping noise on start up until it warms and disappears, as well as some pinging on acceleration.

WHIRRING NOISE CLUTCH PEDAL IN.....MOST LIKELY THE THROWOUT BEARING--EVENTUALLY IT WILL LOCK/PARTIALLY LOCK UP....THE "CLUTCH COVER" (PRESSURE PLATE) ARMS/FINGERS WILL START GETTING CHEWED UP.....THE NOISE WILL MAKE YOU SICK AS THE WHIRRING TURNS INTO SCREAMING!

YOU WILL CRY....LIKE A LITTLE GIRL.....DEPRESSION WILL SET IN

IF YOU GOTTA GO IN FOR THE BEARING---MIGHT AS WELL HAVE THE FLYWHEEL SURFACED AND INSTALL A WHOLE CLUTCH SET

http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_new-clutch-set-perfection-clutch_5332699-p?searchTerm=clutch+set

IF YOU DECIDE TO TACKLE THIS----IT'S NOT REAL HARD---I PULLED MY TRANNY OUT 7 TIMES BEFORE WE FIGURED OUT THE "BRAND NEW" 2ND TO 3RD SYNCRONIZER WAS BAD.......I INSTALLED EVERYTHING, I MEAN EVERYTHING!, IN IT BRAND NEW THE 1ST TIME I PULLED IT OUT......IN AND OUT GOT OLD AFTER A WHILE

SURE THERE'S ONLY ONE "B"?.........THIS WOULD BE A STANDARD (REGULAR OLE DIFFERENTIAL)

WANNA BE SURE?.......GET BOTH REAR WHEELS OFF OF THE GROUND.....TURN THE WHEEL ON ONE SIDE---THE OTHER WILL ROTATE THE OPPOSITE DIRECTION, IF IT IS A STANDARD DIFF

IF IT'S TRAC-LOCTHE OTHER WHEEL WILL SPIN THE SAME DIRECTION AS THE ONE YOU ARE TURNING

GIMME SOME MORE INFO ON THE BOGGING.....IS THE ENGINE NOT FIRING?....DOES IT BACKFIRE WHEN POWER RETURNS?.....JUMP AND JERK? (DURING THE LOSS)...(JUMP AND JERK WHEN POWER RETURNS?).....LAST TIME THE FUEL FILTER WAS CHANGED?......ARE YOU SET UP WITH THE SAME SYSTEM IN MY PIC (ORIGINAL WAY)?

TAPPING?.......THIS IS TAPPING/RATTLE UPON ACCELERATION MOST OT THE TIME......NOT A CONSTANT THING.......SEE "AUG 13, 2012" THIS POST

Thanks Medic. Some recall tells me when working on the Jeep in the past, and turning the rear wheels, I vaguely remember turning the one one way, and the other turned the other way so this would be consistent with your statement suggesting it's a Standard Diff.

I'm gonna go through this slowly, and digest it all, and try and provide you as much info as I can. I will be in touch. Just to let you know now, I will be away September 15-29, so will likely be away from the PC during that time.

Medic, I am hoping the source of the Knocking sound is solved. Found two tranny mount bolts sitting, yes sitting on top of the skid plate directly below the tranny. Thinking under load, the tranny was torquing and doing the knocking.

I will get re-installed and follow-up. In the meantime, thanks for all the info. I'm going to be going over it.

https://www.2carpros.com/questions/2007-jeep-wrangler-front-end-shaking

SO DO YOU HAVE IT FIXED?

BETTER USE SOME LOC-TITE ON THEM BOLTS!

PIC IS OF THAT JEEP--IT, LIKE MY 1ST ONE, I HAD SUBJECTED IT TO A GOOD BIT OF HELL DAMAGE, BEFORE I HAD TO GET ANOTHER ONE........THIS WAS PROBABLY THE NICEST JEEP I EVER HAD/HAVE BOUGHT (NO ASSEMBLY/REASSEMBLY REQUIRED).....READY TO GO....JUST ADD WATER!

GOOD MEMORIES.....BAD DECISIONS

Not having much luck. As I said, for the '86, it only shows the Automatic Transmission, and have searched prior years and jeep4x4center (Morris), but no luck yet.
