469653 2006-07-11 02:50:00 Dont know who said it, but i complete a deal for a calais supercharged V6 tomorrow, it is automatic, but reckon there will be few cars to match it over 1/4 mile. SolMiester (139)
469654 2006-07-11 02:51:00 ... but i do know some people that drives with both feet

As a cyclist, I'd prefer them to drive with both hands, and to use their brains instead of their cellphones.

469655 2006-10-06 13:39:00 I have a 98 Chrysler Concorde, and have been parking on a sloped driveway. I am afraid that i have bent the Parking pawl. Is there any way to fix this, or do you need to replace the whole transmission. Any help would be appreciated.

Hi..(back from a several days off for surgery thing)....

I suspect that there's less damage done to your transmission than you think.

The robustness of the internal parts of the transmission, especially the park parts, leaves me to think the true problem is likely an external linkage thing.

Suspect that if you were to disconnect the external linkage and test the park holding power that way, then things would be ok. Your problem is not uncommon in vehicles that are parked on strong inclines with just the park arrangement engaged with the gearshift and not using the parking brake first.

I usta see this problem from time to time, (and many times more often) on Chrysler econobox type cars (K cars..etc) that the driver failed to use a certain etiquette in parking on an incline.

1) stop vehicle
2) apply parking brake HARD!
3) set transmission in PARK.

When starting to drive away again:

1) place transmission in chosen range (forward or reverse)
2) release parking brake
3) drive off

The whole idea is to make the primary parking-holding-stationary-unmoving thing the job of the parking brake, not the transmission.

I don't truly suspect there is internal damage...let me know.:thumbs:

469657 2006-10-07 03:09:00 Can someone advise whether this habit I have is beneficial to the car or not. When waiting at lights I will take the car (2001 Camry automatic) out of gear into neutral. Thinking that it saves petrol and wear on the transmission/brakes. Is this worth the effort or no real value? ben28 (9007)
469658 2006-10-07 05:18:00 There would be no wear on the brakes as there's no movement to wear them. I don't think you'd wear the torque converter out as there's negligible heat getting generated. You'd save a tiny amount of fuel but I think that's about it. Not really worth the bother I reckon. george12 (7)

Thank you Ben - the very question I wanted to ask !!! Been wondering for a couple of years. Our car manual is in Japanese so we feel very restricted.

One reason to NOT place the transmission in neutral is that you are doubling the wear on the forward and (if it's the front wheel drive model) the low/reverse clutches .

These clutches are not designed to absorb a lot of motion and heat, as they are quite small and when you take the trans out of gear, you need to apply pressure to re-apply them when you choose to go again . That constant engagement-disengagement-reengagement is a lot of extra wear and tear on them .

The forward clutch pack stays on all the time you are moving in forward gears, and only releases when you go into reverse normally .

The low/reverse pack is just being asked to make about a 200% increase in duty cycle, of course wearing it faster when you use neutral at a stop and then reapply it to move .

One good thing is that your transmission is particularly robust and will probably not be as adversely affected like many other designes would .

Would the above apply to a CVT transmission . ?

469662 2006-10-07 20:05:00 Anyone ever have the fun of the late 1960's Datsun 310's or F-10's for a clutch? Like changing a record on a turntable . . . very easy and a lot of fun too! The clutch was in the front of the engine a la' Saabs, and you had a small cover over the input shaft . . . 4 bolts I think, pull the shaft, unbolt the pressure plate and pull the whole thing out without seperating the engine from the transmission at all! Damn! . . . wish they still made them!

well an inteligent designer of cars at last
