Hi there,

I just bought a '76 SII XJ6 that is in excellent condition. Body and interior are pristine, but the car does need some mechanical work (car was driven from '76 to '90, stored from '90 to '10, and from '10 to '15 was only driven about 50 miles).

So I am new to the world of Jaguars, but I am a "car guy." So, my initial set of questions for you guys is:

1. Is the transmission service a simple drain and fill, or will I need to drop the pan, change a filter, service something else, and get a new gasket?

2. Any recommendations on rear differential fluid? I typical switch all my cars to Red Line Oil (they recommend their 75w90 GL-5 fluid), but I've been told that (Chevron) Delo conventional differential fluid might be the better choice in this case.

3. I am new to the world of British cars, but do the collectors and owners have a preference when it comes to service parts? I've also thought of things in this manner:

Denso or OEM (Honda/Toyota) for Japanese cars
AC Delco for GM, OEM Ford for Ford, (never worked with Mopar)
Bosch for German

Any thoughts would be greatly appreciated!

 

(Sorry, I can't seem to find the edit function for this message board.)

Also, as it relates to the transmission, my plan was to use Red Line's Racing ATF (their recommendation) and install a Magnafine inline magnetic transmission filter.

Any thoughts or experiences on this plan?

 

congratulations!

the XJ-6 uses a number of GM / Delco parts, including the transmission, a/c compressor, and a lot other parts but I am mostly familiar with the Series 3 (1980-1987 XJ-6). You have a Series 2.

to service the transmission, drop the pan, drain the fluid, replace pan gasket and clean the mesh filter, refill with proper amount of fluid. Messy job. I am not familiar with the Red Line's ATF but someone here might know.

I suggest that you purchase a Service Manual and a Parts Manual if you are going to start servicing the car, it will help you get to know the car and save you a lot of mis-steps. Overall, these cars are analog, (as opposed to digital as most cars are today), mostly easy to repair by the do-it-yourselfer. Parts are plentiful used or new.

Contact David at Everyday XJ and ask him if he has a used Service Manual and a Parts Manual for your model-year, right now he is sellling many used manuals in good condition. Also you can get the information for the proper oils from the manual.

Jose:


Great advice. But, I think that GM cars never used the BW, "Borg Warner" transmission.


Borg Warner is a maker of power transmission things from way back. Ford did use a version known as the FMX for a time.


I have a vague recollection that GM's Allison divison is responsible for GM's various auto boxes, going back to the first two speed Power Glides and before that in about 1938, Olds offered a Hydramatic percussor. The Hydramatic was a big, heavy and tough four speed. My 55 Olds 98 Holiday coupe was so equipped. Very lively in spite of it's size and avoirdupois !!!

Carl you are correct, his S2 car might have the BW-35 transmission, while the S3 has the BW-66.
I always get Borg Warner confused with GM. My '65 S type has a DG-250 transmission first used in Studebakers!

Series 2 - The power door locks are Chrysler units, and the side rearview mirrors are American Motors Hornet mirrors

 

Jose,

Thank you very much for your reply. The information and links are very helpful. Hopefully I won't find any "surprises" in terms of major repairs.

So the Service & Parts manuals you recommended are better than the Haynes' manual? I have one on order from Rock Auto but will gladly grab the other ones if they are more useful

Thanks again!

 

Haynes manuals are a joke, don't throw money away. Buy the FACTORY service manual, you can also get them in CD from the Jaguar Daimler Heritage Trust in the UK and some sellers in the US

did you check with David ? he shows up around here sometimes. For me the bound paper manuals are better, takes forever to open the CD in the computer.

Jose is right, the Haynes manual is useless. Bentley publishing prints the factory manual.

Bentley Publishers - Repair Manuals and Automotive Books.

 

yes, those, although he could get them slightly cheaper on eBay, and maybe from David Boger.

 

The Series II Borg Warner "Slushbox" semi-automatic transmission has the same internal parts as a 1961 Rambler car transmission.
It's a useless piece of obsolete junk and has a mind of its own, when shifting.
I used my Coupe, long enough, to understand the transmission.
You are better off to change it out to a manual stick trans.
A lot less maintenance, more HP and better fuel mileage, providing you install a 2.88 rear end pumpkin.

 

He,he, Haynes.


It wasn't long after I got my S3 in 2001, that I saw a Haynes publication on a shelf in a parts place. Yahoo, that is what I need to understand this new critter. Nope, the opposite. Actually a lot if not all of the material is copied from Jaguar publications. Sounds Ok, but it is not. originaly edited and organized based on the S! and S2 cars. So far not too bad. but when they spliced n the S# section, things went FUBAR!!!


The electrical schematics are particularly maddening.


I have the Jaguar Service Manual on disc and on paper. Much better, but a bit lacking in detail. I looked up S# ignition switch n light of my resnt electric problem. Remove the housing undo the two screws, etc. A scrawny drawing helped only a tad.


The Jaguar S57 publication is a collection of electrical schematics for the S3 car. Excellent. It has saved me and many another. I've scanned and sahred pages with many over the years.


Listers here and elsewhere are much better technical writers.


My Jaguar lore is extensive. But, "organization" is lacking. Understatement of the year!!!


Got to tackle the start run issue again. it is in the wires where Jaguar becomes GM. So, a bit from my jaguar schematics and a bit from the GM FSM, the latter a huge tome with excellent material.


But, in defense of both publications, they are written for professionals, and I am sure not at that level!!

Is the 2.88 ratio OK with the standard 4.2 carb engine?

 

Thanks everyone.

No one has an opinion one way or another as to which fluid I should use in the differential?

What does everyone here service their diffs with?

 

I've always used garden variety 80/90 GL5 gear oil in my Jag differentials....whatever brand name was on sale that day. There is nothing unusual or exotic about the Jag differentials of this vintage.....so no unusual oils required.

Some prefer synthetics....purely a personal choice.

Cheers
DD

 

Thanks.

And how many quarts does it take to service both the transmission & the differential?

Thanks.

 

Yes. Great hiway cruising ratio.

 

I'm fairly certain the Series 2 cars used the BW Model 65 box although maybe not until the cars had been in production for some time. I think the BW66 came in with the Series 3s. My Series 3 was a BW66, which was a slightly improved 65.

Jaguar used a GM Hydramatic box on the V12s from 1977.
