This'll probably be something that the dealer is going to have to do. It's a pretty unusual system & I don't think I'd want a general-purpose garage learning on it. Good luck.

Replying to: cep (Oct 11, 2007 7:39 am) Now I have a quick question that maybe you have some insight or opinion on. It's just a crazy idea I've been pondering. No, not the one involving Salma Hayek. This is about my stick-shift Lincoln and gas mileage. You and I know the LS 5speed is a pretty good car, n'est pas? Sure, it could use a few more HP (like maybe 80) and a bit better mpg would be nice too. There may be ways to get the HP, but this idea only addresses the mpg. Part of the problem is the 5speed has a 1:1 final drive ratio. THis causes the engine to turn at, what, 2500-3000 rpm at highway speds I think. I should have verified the number b4 I wrote this, but my wife is pretty much the sole driver of the LS now. Anyway, highway mileage should increase if the engine rpms decrease eh? The tranny is a getrag. getrag also makes 6 speeds. I admit I havent researched at all, but I'm thinking a 6 speed might have a lower final drive ratio? Perhaps finding a 6 speed getrag on a bimmer in a junk yard somewhere and modifying the spline might provide a nice improvement in LS mpg, and maybe increase the torque handling number so that the HP increase could be addressed too? Any thoughts? Yeah, maybe that Salma Hayek dream is more easily achievable?

Replying to: jeyhoe (Oct 11, 2007 8:13 am) Anyway, making a transmission swap in a car like this is certainly an ambitious project. I doubt seriously that the 6-speed has the same external dimensions -- it's unclear that it would even fit. You might be better off going with a taller rear-end ratio, which would of course affect lower gear acceleration as well. I also don't know if the Getrag 6-speed you're considering is an overdrive unit. If not, you won't accomplish anything in the top gear. Good luck. I wouldn't touch what you're contemplating with an 11-foot pole. |

Replying to: akirby (Oct 11, 2007 9:02 am) I'd have to enlist the aid of a friend who's a mechanic and his answer to these types of questions is always "anything's possible"  If I ever do attempt it, you'll be first to know. Also, the only time i ever got 26-27 mpg was when I tried "hyper-miling" It does work, but geez, takes a lotta time off ones life and really p*sses off other drivers. My basic commute mileage when I used to have a job was around 21-22 and that was 95% hiway. Oneof my problems is I'm using California gasoline. Another is I drive 75 or so if I can. Are you a slow driver? Just askin!  akirby: Very funny Actually I think the answer is about 1500 people, though I'm not sure of accuracy of that. Well, actually the number who would WANT a stick shift Lincoln is probably higher, but dealer refusal to order them kept the number low. I wonder what the ratio of auto to manual is in the CTS? The bimmer? Volvo? ...

Replying to: jeyhoe (Oct 11, 2007 9:22 am) I think the final number was around 1800. I'm sure the CTS is similarly low - probably 5% or less. Even the BMW manuals are rare - less than 20% IIRC. I love manuals but I got tired of them in my boring daily commute, even moreso when I get stuck in a long stop-no-go delay. I'm waiting to buy a used 06 GT Mustang with a stick for weekend fun. |

Replying to: jeyhoe (Oct 11, 2007 9:22 am) Nope. That trip to AK included lots of time at 75-80 and a number of hours between 80 & 90 -- gotta love driving through Eastern Oregon & Nevada. A few years ago I had the opportunity to set the cruise control at 105 on U.S. 60 in New Mexico & leave it there for most of a half hour. Spent much of the rest of that day well above 70. My engine was carefully broken-in, which takes at least 5000 miles before the fuel mileage starts to get reasonable. Synthetic oil (Mobil 1) could be a factor as well. |

Replying to: akirby (Oct 11, 2007 9:02 am) to you too! I enjoy that manual every day, as I slip it into neutral & wait to see how slow I'll have to go in the upcoming traffic "situation." Sometimes I drop one gear, but more often it's two or three, before I slip it back into gear -- could be two seconds or 30 seconds later, jerk-free, engine at idle speed all the while. Gotta love traffic jams. |
