Even if it were possible to physically install a manual gearbox into an S-Type R, how are you going to get around the TCM, which communicates with other control modules in the vehicle?
Perhaps it may be best to describe the conditions, symptoms and other relevant information so a correct diagnosis can be made. Most of the time the gearbox is not the culprit. Is the MIL on, and if so, what are the DTCs stored in the system? Post them here so the forum members can offer help and ideas.

Jag V8,it's simply that-my thought. Being a forum, my bad for assuming one could ask a question and voice an opinion to seek an answer. STR 2004, I didn't realize other manufacturers build an STR and that they would post on a Jaguar forum, again my bad. NBCat, thanks for the info- again, as I'm not familiar with all of the elements regarding a potential trans swap how would I know about the TCM or other devices? I am aware of them now and am gaining much insight into how much more is entailed with the possibility of a trans swap. Regards to you all/

I'd suspect by making a vague but derogatory comment about being a disaster you quickly alienated about 50% of the 'peeps' that might otherwise respond, having dissed their cars, so your bad on that one.
By criticizing the few responses you did get, I'd say you lost another 49%.
Jaguar did build a small number of S-types with a manual trans but all had V6 or diesel engines I believe.

Hi blackcat03,
Welcome to the Jaguar Forums! Sorry it seems you've gotten off to a bit of a rocky start, but we're really a friendly bunch.
Please visit the New Member Area - Intro a MUST - Jaguar Forums - Jaguar Enthusiasts Forum and post an introduction so we can learn something about you and your Jag and give you a proper (friendly) welcome.
Cheers,
Don

Anything is possible with money.
NBCat is correct though. Getting around the TCM and other modules will prove to be an absolute pain. Unfortunately, the money and R&D that goes behind a project like this will far outweigh the benefits and joy of driving a manual STR.
As long as you maintenance the vehicle properly, your transmission should last you the lifetime of the vehicle. I know there are some scary stories on the forums about the ZF transmissions, but for the most part it's pretty much bulletproof.
A buddy of mine has a STR with 178K miles on it and the transmission still shifts hard and strong. And this is a guy who has done multiple launches and hard accelerations with his STR.

motorcarman, typical onliner smartass-comedy and Mikey I don't recall dissing anyones damn car. I merely made a comment on the transmission in my car which happens to be in their cars (no ****). I love the car, one of the best I've known but the whole being a smartass on line is beyond me. Agree with me or agree to disagree but disrespect on a personal level, that **** isn't going to fly. Jag V8, I'm sure my choice of words weren't the best. What I'm experience is this: occasionally while I'm braking ( above 30 mph or so) the transmission won't downshift, instead the car will slow normally and then I get a "transmission fault" reading. Once that happens I lose 1st and 2nd gear unless I turn the car off and restart it-at that time the fault reading goes away and the car operates normal. I found on here elsewhere that It may be the torque converter so I'm looking into that. I can understand your tone as well but **** people, it's simply my opinion or poorly worded sentence. I've got real life **** to deal with-online toughguys are the least of my concerns. If have any advise great, it would be appreciated-if not, thank you for your time

You're describing a fault with your car. It looks to be a very rare fault, one that other cars don't have.
I can't see it being the TC.
It's probably diagnosable but nay need an expert and may well not be the trans.
Most weird faults like that turn out to be power related, usually a failing battery.

blackcat03,
A generic OBDII scanner can read the Powertrain (P) Diagnostic Trouble Codes (DTCs) which are triggered by transmission issues, but it may not be able to read any of the proprietary Jaguar codes (B (Body), C (Chassis) and U (Undefined, mostly network communications-related). With your symptoms, you could be having problems with communications between various modules that are involved in managing gear selection and smooth shifts (Engine Control Module (ECM), Transmission Control Module (TCM), Throttle Position Sensor (TPS), Mass Airflow Sensor (MAFS), etc.). I wouldn't be surprised if you have at least one U code stored, so depending on what your first OBDII scan turns up, it may be worth finding a local shop equipped to read the proprietary Jaguar codes to help narrow down your diagnosis.
I'm attaching the 6HP26 DTC Summaries, which contains the P code definitions. The U code definitions are in the Electrical section of the workshop manual.
Please keep us informed.
Cheers,
Don
