Title pretty much sums it up.

108,000 miles.

Transmission rebuilt 15,000 miles ago.

Car recently started hesitating going from 1st to 2nd.

Today car slipped gears going from R to 1st. Took a few seconds to grab.

Picked up a few quarts of recommended fluid.

Where the heck do you fill the stuff?

Thanks

 

The fill check plug is on the right (passenger side) rear corner of the trans. It is an allen key. Check some other threads, there may be more info. From my experience, your description is a sign of the trans needing to be gone through.

 

Check out this link for the capacities: https://www.jaguarforums.com/forum/x...04/#post620985

Also, get a trans fluid dipstick or measuring tool. I have an XJR with a MB trans thats different from yours, but check the forum. Its a pretty common topinc.

 

OK

Beisdes anything having to do with the transmission itself or lack of fluid, what can be some other reasons? Low motor oil, fuel injector, etc...

No transmission warning lights go on EXCEPT for last night when the car didn't engauge from a stop until I cycled trough the J shifter. upon restarting the engine the light went off. Also slipping seems much more pronounced as I accelerate with more force.

I want to add fluid, but from what I gather this is NOT a DIY project since there isn't any way to just pour fluid from above.

Please correct me where I may be wrong.

Thanks for everyone's input!

 

These transmissions have to be filled from underneath the car-your has the ZF 5HP24 transmission. Follow this link for the transmission filling procedure-it's from a BMW website but many BM's used this gearbox as well:

The transmission is also known as the A5S 440Z. The 440 part of the number is the torque handling capacity of the gearbox in nM, NOT lbf/ft

 

Coastal,
You may be correct, but.....

So you are saying that it has to be filled while the car is on jack stands with the rear wheels spinning and drive shaft spinning right next to the tranny? And you have to crawl underneath all that moving metal?

That sounds so far from a safe procedure my only comment would be to proceed at your own risk of life and limb.

The rear wheels don't need to be spinning under any circumstances-this is highly dangerous and is NOT part of the official refill procedure dictated by ZF!!!

The procedure is to have the engine running with the handbrake on, apply the footbrake & slowly run the gear selector through all the positions about 3 times. This is to 'prime' all the fluid channels in the transmission with fluid. If you don't do this, then the fluid level will be artificially high when you remove the filler plug & fluid will leak out.

Then you put the gear selector in 'Park' with the engine still running, and check the level by removing the filler plug at the correct transmission temperature-as specified in the refill procedure. If any fluid leaks out, then the original level was too high-if no fluid leaks out, then fill with more fluid-maybe using a hand pump/syringe-until the fluid starts to leak out.

Then refit the fill plug & job done-all without the wheels spinning, as it's really not necessary or even part of the official filling procedure

 

The transmission should be between 30 and 50 deg C when adjusting the level. I use a indoor/outdoor thermometer with a sensor that can be pushed into the fill hole. As the temp. rises more fluid will come out.

On my XK8 I disconnect the transmission cooler return line at the top of the radiator and replace the fluid using my mityvac pump. Less messy that way.

 

I had a helper and anytime u get under a car it's dangerous. The wheels weren't spinning at100mph but mine shifts smooth as glass.

 

The point of the argument is that there's no need to have the wheels spinning-it's not necessary & not part of the official filling procedure. Once the gear selector has moved through all the positions & 'primed' the hydraulic circuits, it's then placed in 'Park' & then you can check the fluid level with the transmission safely locked in 'Park' & the wheels/propshaft stationary & locked.

That's the official procedure...

Yes, it's dangerous to get under a car-but it's even more dangerous to get under when the wheels & propshaft are spinning, especially when it's just not required to do that. The transmission can be left in 'Park' to check & top-up the fluid level.

Your method adds danger when it's not even required, as the official procedures do not require the wheels to be spinning anyway-so what's the point? The transmission can be left in 'Park' to check the fluid level-and that's official-from ZF themselves, who make the gearbox

 

Thank you for being patient, Red October.

 

There are transmission shops that are honest and not too $$. It is ok to
get help. There are still plenty of other repairs one can do to keep the operating cost down. Do the repairs you are comfortable doing.

 

It's dangerous, reckless and not necessary.

Therefore, recommending it is foolhardy when there are readers of all skill levels on this site.

don't know about the 01, but my 98 xj8 vdp and 2000 xjr have a 1/2 in tube sticking up beside the the ecm box . vent tube i guess. i just drained mine . left the fill plug out and poured the atf down it like normal until it ran out. got the atf at O'Reilly for 15.99

 

another thing. are all jag trans made by zf in germany. but just diff models of it.

 

Your SC model has a Mercedes Transmission, while the NA engine uses the ZF 5HP25. If you have a fill tube on the VDP it is an aftermarket addition.

 

changed oil in all of them sunday. guess what all of them say zf made in germany. three have vent tubes by comp box. all can't be aftermarket. 3 out of 5

 

needed some other parts for a customer, so i stopped by jaguar. yes all of them could have zf's. can only tell by vin. and we sat down and went thru parts books. tube # is nnc4540ae. they call it a dipstick even though you can't put any thing down it.and it's suppose to be only on sc's. i took the shop forman out and showed him mine . he blames it on ford.

 

Could you entertain us and take a picture of this ZF dipstick tube please?

 

must have been a blonde thing. both trans are made in germany. zf 5HP24 and W5A580 will try to upload a pic when i figure out how. got the pic but i'm dumb on computors . spent 22 yrs in military as a motor pool sargent ,14 with fed ex . shop foreman, 15 with cummins diesel as a shop foreman, have my own shop now ,but these jaguars are killing me.
