ZFHP22 in Defender problem

Posted this here as its not specific to one model..

I DO seem to have a problem with the box :(

200Tdi Discovery dox in a defender (unless it was a flippin v8 one) bought as kit with eveything to fit the 200

so pulling away from stopped it shifts up through the gears fine 1/2/3rd or so I think, stop at the end of the road, but get out pull away and I now have no upshift - 3000 revs and feels like its stuck in 2nd if I ease off nothing happens !

Truck undrivable at mo :( :( :(

Dont know if something has shifted on the kickdown that I'm unaware of, I'm no pretty much nowt about auto's :lol:

Any pointers, ideas, or will it be Land Rover adjusting tool no 1 to the flippin thing !

Check the kick down cable isn't seized, if it is seized in the 'pulled' position, then it will think you have your foot hard on the floor all the time. Could have got snagged/melted...?

As above though, fluid is pretty critical, is it clear in colour? Metallic flakes, grey/browness is all bad news.

How many miles done since fitted?

Tried it in reverse?

Tried it in '1'?

Checked the cable all is ok you can feel it going into the kick downposition.

Miles since fluid and filter change, 600 perhaps, I have done one fluid change since, given I thought the new fluid might dilodge some gunk so intended on changing it a few times to be on the safe side.

Now I'm on the outer most hole of the kickdown bracket which as in further out from the pivot point gives the greatest movement of the kickdown cable.which could be making the box think i'm on fullthottle all the time ? perhaps the bracket has moved, although I seem the remember it had locating pins !

Has anyone a pic of a 200tdi kick downset up for me to compare loactions of against

Pulling away slowly from a stand still it all seems to shift properly, when I pull away to get up to speed it get to 25 its doing 3k revs and nothing shifts up ?

Reverse again is all fine

I have my cable on the inner hole also, this gives the softest upshift. I had it on the 3rd hole to start with and the shift point was very high.

New fluid does tend to clean out all the muck, this gets lodged in the governor and the box will be slow to shift out of 1st until it warms up. I changed my fluid 3 times and eventually had to remove the governor and clean it out. It's been fine since.

My box had been stood for a long time and I've no idea how many miles it has done.

There's always niggles to sort out when the builds done though. Just when you think you've finished!!

The set up for kickdown cable is with cable connected operate accelerator pedal so that you get the kickdown "jump" just prior to the accelerator pedal getting to its limit of travel . There should be a crimped metal tag on the inner cable to limit the cable going back into the box .This is with having already adjusted the acc cable so that it is almost at full travel when pedal hits floor stop , so that you are not using the cable as the limit stop.

Errr I assume that you have installed the correct torque converter - the one you installed, if it came with the second hand autobox could be for a V8 which has a totally different converter, same goes for the governor - it has different springs in the centrifugal control.

I feel your pain Les, I've just spent almost a week of my life trying to solve why my heated rear window continually bows fuses. Last night I found out why; someone, when putting the rear door back on, decided to use the wiring as a hinge gasket......
