Hello everyone, I have a 05 Jaguar S Type R and my transmission is bad, I found another good used one but it's out of a N/A V8, would that still work on the R model? I have a jlr sdd and i can clear the adaption, also If it is the same transmission but different software, i can put my TCM/TCU on that good transmission and be done, any help would be greatly appreciated. I can't find any info online about supercharged and N/A transmission interchangeability.

 

Not sure but do you have the JEPC? Jaguar Electronic Parts Catalog.
It's free on this site and you can look at part numbers to see if they are the same.

No I don't have the JEPC but I'm downloading right now. Was wandering if someone had a first hand experience in them, i would assume is the same transmission just different software maybe, I ended up purchasing and gonna open it up and see what's different. Hopefully nothing and I dont have to swap parts out of my old one, maybe the computer. Hope all works out and I will update this thread, maybe itll be a help to someone some day. I'll keep my old trans and rebuild it slowly since the parts are so expensive and have it a spare or sell it and get my money back.

 

Looking a little deeper I think you will want a unit from a SC car?
This is from the attached ZF document.

From my understanding you need a trans from a SC model.

They are not as available as the N/A transmissions. Luckily I sourced one from another member just in case mine goes south...

Now I've heard the only differences between both trans is the TCM and Torque Converter but I think the SC units have tighter gears, bands, etc.

 

I really hope only difference is the torque converter and tcm, I can swap those from mine, otherwise I'm just gonna rebuild it since it costs almost as much as the used unit plus shipping.

 

you can broaden your search to X350 - X358 XJR as it is the same unit .

oh and there are no bands in the 6hp26 just wet clutches .

 

I only found 1 transmission that part number matches to mine on the right side of the transmission stamped, they're both 1068010101, all other ones are different numbers minuse the 1068. But I also noticed on the bell housing there is another 1068401111 number that comes up on NA V8s and SC V8s, I will include pics and you guys tell me what you think. There is a 05 STR trans that numbers




dont match with mine and mine is also 05 STR but that 1068401111 number on the bell housing matches, pretty much every transmission made from 04 to 08 for the V8s NA or SC has this 1068401111 number.

 

Only thing I noticed on NA vs SC the torque converters look different.

 

What exactly is wrong with the gearbox presently in the car?

 

Thanks for pointing out.

 

when I select reverse, it takes close to 5 sec to engage and it's kinda hard engagement, engages drive kinda ok, anfter driving it throws the 5th gear ratio code and wont shift out of either 2 or 3, I think it stays in second and MIL light comes on. I changed and checked the fluid and its proper level. I'm leaning towards bad selonoids and valve body, I'm gonna take the valve body out and order a rebuild kit and get tested selonoids also and I'm gonna try to do a air pressure check of the gears. The reason I'm almost convinced transmission is bad, because when i bought the car, transmission had almost no fluid in it, I removed the pan and the valve body, replaced the square plastic pressure seal and all 4 little tube insulators, filled with brand new zfatf1 fluid, the one that is recommended for this trans, and hoped for the best, i did find few small metal shavings on the magnet but hoped it didnt damage anything. I ordered new fluid and pan, gonna drop the pan and start taking the valve body out and rebuild it, i will install it and test it, if it corrects the problem, I'll leave the clutches alone, if not, I'm either gonna have to attempt te rebuild it or buy a good used one. Thanks.

 

You welcome. I'm not sure which part number to go by but that's what I noticed so far.

 

Well looks like i'm gonna rebuild the transmission, i ordered all the parts including Sonnax zip kit, hope it's not too terrible of a job. has anyone here attempted to rebuild their zf6hp26s before that can give me some advice and difficulties i will run into? Been watching youtube videos and searching the net for a wile now, does'n look too hard of a job. I already removed the valve body and transmission is 80% out, i need to disconnect driveshaft, trans mount and torque converter and its out. The bell housing bolts were not too har besides the top 2, i had to remove both catalytic converters and cabin air filter box to have easier access to top bolts, iv'e attempted to rebuild 4L60E years ago and failed, hope it'll be easy this time around.

 

Since you've decided you're going to overhaul the gearbox yourself, here are links to the ZF repair manual, parts catalogue and filter/pan torque sequence:

Wow this is gold, thank you so so much NBCat

 

 

And why would you not change these parts?

If you don't want to order new parts, purchase a used gearbox and swap the parts.

Follow the instructions in the ZF Repair Manual. These gearboxes are quite robust.

 

NBCat I'm replacing all the clutches and the metal separators, my question was about the drum itself where clutches sit in, I'm acually looking for a used drums to replace the discolored ones. I'm almost finished with the valve body, installing the zip kit now.

 

Yes, replace the drum by all means.
