: ZF kickdown cable replacement/adjustment
PTSchram 04-09-2006, 04:14 AM Have you ever spent HOURS wrenching, only to get the end to find the results were less than you'd hoped for?
Yesterday, Pinnochio, my ragged-out trail Disco got a tranny transplant. I replaced the original one due to a horrible front pump seal leak, many, many, many miles and a transfer case that had been run dry for God knows how many miles-fuel mileage had fallen into negative numbers, I'd assumed from drag in the T-case. As the donor tranny had come from an arson victim, the tranny got a new filter, kickdown cable, pan, dipstick, etc (being able to look over your shoulder at the parts guy and order your parts for immediate delivery rocks!:flipoff2:-just remember, I now have to actually pay for them ).
Got the tranny in and the damned things shifts kinda funky. Revs out too far, seems to rev too high. Both of these were complaints I had with the old one.
When I replaced the kickdown cable, the new one did not have the all-important ferrule crimped onto the cable. The FSM said to transfer the dimension from the old tranny. I did so-BUT I transferred the dimension fromt he one that came out of the truck, not from the one that went back in D'Oh (recognize a recurring theme here?).
Does anybody know how they determine the dimension on brandy new trannys? Pendy? Ashcroft? Anybody?
While I was under there, I also discovered that the pinion bearings in my front diff are pretty well knackered. AFI's been asked to send me one out of the parts trucks he hauled out of the old shop...
Just my luck, I move to a place with great nearby wheeling, work at the place where they are ebst able to get my rig going and I still cna't keep the damned thing going.
Peace,

I'm not sure that the kickdown cable crimp adjustment will produce the effects you mention(unless you pulled the cable out and then crimped it). I've seen the things all over the place,(I've never even crimped the one in my heap 'cause I wasn't sure where to crimp it) My manual says to leave a .25 - 1.25 mm "crimp gap" to the housing, after setting the selector linkage. I would assume that if you haven't reset the selector linkage then the "crimp gap" would stay the same.
The symptom you describe, hanging on to a gear to long, in my experience has been due to either low main line pressure, or knackered T-converter.
Hope that helps
Junkyddog11 04-09-2006, 08:12 AM Oh yeah and the HOURS wrenching. I replaced the ailing 400k mile tranny in the Slut with a tranny and T-case from a "low"mileage '97. Fawkin' thing slipped and shook like a good Jamaican stripper:eek: . Changed that out. Put newer T-case back....it whines so loud at 40 mph, people in front of me look in their rear view and get ready to pull over.:D

Thanx for the input.
If I don't put my foot into it but gradually accelerate, it seems OK.
The torque covnerter out of the original tranny WAS however knackered. The steel sleeve on the tranny side had turned a very pretty color of dark blue-I think it would be a good color for a truck or a shirt.
I was thinking I would adjust the cable so it was almost slack and see if this resulted in a change. The tranny had sat for at least a year or two before being fired up.
If it's a dawg, I have two more and if I buy the RRC in the shop, I'll have yet another and another non-serp 3.9 (for what this one might be worth).
Oh yeah, I have Slade's shifter and tranny mount now too:D

Not to mention my cell phone charger and my power inverter. :flipoff2:
Junkyddog11 04-09-2006, 04:02 PM I'd bet the tranny having sat for a while might not help. I've had'm behave like you say when the filter is cagged up (low pressure) or just low fluid. If your luck is anything like mine with my own shite, it couldn't be that simple though.
I'll put my LT230 parts back on the shelf for now.:flipoff2:
PTSchram 04-09-2006, 06:47 PM I readjusted the kickdown cable and I used less fuel to go further than before. I feel much better about the swap.
Mike-I'll try to get your stuff shipped out this week.
Peace,

Thats sweet man.
I'm throwing an R380 in the Slut when the Tdi goes in. I'll be so glad to get away from the auto, not that there is anything wrong with them, and I'll spill even more coffee.........
pendy 04-11-2006, 10:19 AM Yes slack in the cable could help your problem. As could a Exican tune up.
Put the shifter selector in 2. Drive up past 25-30 miles per hour. Make it down shift into gear 1 a few times on a warmed up engine. That will clean out the govenor passage.
Should have had the torque convertor rebuilt. Money well spent considering the labor to get it installed.

Where the Hell were you when I needed help??????:flipoff2:
Labor cost? I make friends easily, but you wouldn't understand it as I'm one of the few you can afford.:D
It's amazing how easy a tranny swap is when you have the right tools (the tools most of us mere mortals have only seen printed in the FSM really do exist and work real well!) and a four post lift. I've become spoiled. Really spoiled. A lift, real transmission jack and the fixtures made it an easy job. I finally understand how folks can do this job in 6.90 hours.

pendy 04-12-2006, 10:58 AM Six hours at what per hour, your stealership? What is your labour rate there?

Saturday rate with the shop foreman helping. It cost me lunch and a full growler of good beer.
I told you I make friends easily:flipoff2:
Oh yeah, I gave him a BTL oil drain plug socket too:D
