Hello folks,

Does anyone know the proper part # for the XJR transmission filter and gasket kit?

I am trying to order a kit but there are 2 separate part #s listed:

ACDELCO Part # TF249

and

ACDELCO Part # TF329

Also, is there a drain plug on the torque converter? If not, what's involved with disconnecting the transmission cooler line? Which port on the rad is the inlet (oil going from trans to rad) and which is the outlet (oil going from rad to trans). Does the fitting require a specific gasket, or just a generic copper washer?

Thanks.

 

I used a TF249

No drain plug on converter

Can't remember which line is inlet/outlet. Sorry.

thanks Doug

I consulted the Jaguar Heritage site, and assuming that I am reading the diagram correctly, it lists the upper hose as the oil cooler return pipe and the lower hose as the oil cooler output pipe.

I will order 2 sets of O rings and try to do a drain/refill.

 

The trans pan gasket on my XJR is a high-quality item with steel bushes at each bolt hole and an embedded rubber seal (like an o-ring but shaped to follow the contour of the pan). After a filter change I reused the gasket and so far it is not leaking.

 

Interesting, I ordered an OE gasket for the 4L80E in the XJR and it turned out to be a paper/cork unit that is not the rubber/o-ring version noted above, although it does have a Jaguar OE sticker on the package.

I've seen other images of the JLM10975 gasket however that is the version noted above that is rubber with metal o-rings.

I wonder which is the correct gasket for the X300 XJR 4L80E, the "cork" or rubber/o-ring version.

The image from the parts manual would seem to suggest the rubber/o-ring version:

I bought my XJR at 30k miles so I'm assuming that it had the original gasket....and it wasn't cork.

I'm not sure if I'd call it rubber, either. But, whatever it was, it wasn't cork !

I hear ya, here's a photo from Terry's Jaguar of the "cork" (ish) version of the JLM10975:

 

I ordered a replacement gasket from Coventry West and it turned out to be cork. It leaked like crazy so I found the original rubber one on UK eBay and no I'm good.

 

I bought a transmission filter and gasket from "advanced auto parts" and it came with a rubber gasket.It only cost me about 17 bucks.Now i just need to do the job and im not sure if i should mess with the tranny cooler to drain the tranny and replace the filter and gasket.Does anyone have a ny input ?It would be greatlu appreciated.

 

Well, we all have our comfort levels and pick our battles when it comes to DIY auto maintenance time and cost. And I'll tell you that the older I get and the less time I seem to have available, I opt to DIY the "interesting" stuff and more and more often let shops do the routine, PITA and frankly unenjoyable stuff if reasonable cost.

One of those will be the transmission drain, filter and gasket.

Jaguar of Cary quoted me $180 if I provided the filter and gasket, since I already had it. And I'll probably provide the Redline fluid too, so the cost should drop some.

Given the mess, and inconvenience of the whole affair, I'm thinking ~$150 is well worth having someone else do it, and do it right.

It's not that I can't do it, but I'd rather do something else

Al,

Out of curiosity, which Redline ATF are you considering using? D6 or D4?

Cheers,

Don

 

From what I've read, the D4 makes more sense for the 4L80E.

I doubt either would be a problem though.

If the original fluid spec for the 4L80E was Dexron III, I think you'll be happier with D4.

Our '93 XJ40 has the same ZF 4HP24 as in the N/A X300s, and when Dexron III was discontinued, I began using Dex VI, which was claimed to be backward compatible. It wasn't until years later, when I tried Redline D4 on the recommendation of a friend at the Jag-Lovers forum, that I realized the torque converter had not been locking up properly. With D4, I suddenly had engine braking again when downshifting to descend hills, and in Sport mode the transmission held lower gears much longer.

I did a little research and learned that even though the more modern fluids claim to be backward compatible, their viscosities are significantly lower than Dexron III and there are probably other substantial differences, such as friction modifiers. BTW, one of the things I learned was that one of the friction modifiers in the original Dexron was sperm whale oil, the importation of which was outlawed by the Endangered Species Act of 1973, so GM had to change the formula to Dexron II.

Anyway, if Dexron III is what Jaguar/GM recommended for the 4L80E, then I think you'll be really happy with D4.

Cheers,

Don
