Hey peeps, I've got a question: Has anyone tried or heard of anyone re fitting a manual transmission into an STR? Different tranny with adapter plate? I love this car but it's on the way out if I cant swap this auto disaster of a transmission. Anything guys??

 

I believe I recently read here on the forum that it had been done in Europe but not in the U.S....

 

Thanks Jon, I'll look into it. Appreciate it.

 

With the trans also being in Audis, BMWs, even Bentleys & Aston Martins, why is it that you think it's a disaster?

 

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/

 

Other manufacturers use the ZF 6HP26/28 gearboxes on their vehicles and have done so for some time.

What is actually the matter with the one in your S-Type R?

 

Other manufacturers DON"T build an STR BUT they DO use the ZF 6HP26 gearbox!!!!!!!!!!!!!!!!! (your bad)

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.

 

I asked why you think it's a disaster, so maybe you could answer that?

 

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.

 

Perhaps if you had described the fault in the original post you would have got more constructive responses.
Don't forget that intro the link is in post#11

 

Thanks JagV8, I appreciate the response. I've gotten ahold of a ODBII scan tool and am going to pull codes this morning. There is a ton of info on this site, the more I rattle the cage so to speak, the more I find falling out. Again, thank you.


Regards

 

FWIW, the transmission fluid needs to be flushed at the 80-100K mile mark. This may not have been done on your car and might be a contributor to the unusual problem.

 

Mikey, thank you. My service mechanic has been hounding me about that so I have to agree with you. Your input is appreciated.


Regards

 

blackcat03
good luck with your car.
you never get a second chance to make a first impression.

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
