#8 of 87 vibration/snow driving by mystique Mar 04, 2006 (12:22 pm)
I will have the transmission fluid checked thanks. Also many friends in the law enforcement field tell me these cars are like sleds in the snow. I have a ford club wagon as a work van and, although it is much heavier, it is fine for me in the snow. I tell my friends you need to know how to drive in the snow and you should be fine. What should I be looking for? Coincidentally my Uncle is a big volvo person, and all his volvos have been rear drive. He says the same thing, that all you need to do is know how to drive and you'll be fine.
#9 of 87 2005 Grand Marquis (Vibration) by wlppete Mar 05, 2006 (5:54 am)
My last car was a 1995 Grand Marquis....I sold it with 250,000 miles on it and it still drove and rode great. I recently purchased a 2005 Grand Marquis (would'nt have bought anything else)   I drive a lot of miles....since my purchase I have noticed that I have a vibration in the floor both driver and can feel the same in the passenger seat. Mostly at 60-70 mph but can also be felt at lower speeds. For what it is worth....I don't feel the car is as quiet as my 95.   Has anyone else experienced the same? So far the dealership has replaced the drive shaft (indicating they thought it was out of spec) Foreced balanced the tires..(found no real problem)   I have driven another 2005 from there lot and feel some of the same but not near as severe. There indications are that they do not know what to look for next.   Anybody have any help..experiences....or suggestions.   Thanks Replies to this message: g45 (Mar 05, 2006 4:28 pm) cyberwiz (Mar 14, 2006 7:29 am) euphonium (Mar 14, 2006 10:52 am) jsylvester (Mar 14, 2006 8:29 pm) zanzibarjose (Mar 24, 2006 12:11 pm) wgfwli (May 03, 2006 5:16 pm)

Replying to: wlppete (Mar 05, 2006 5:54 am) A challenging dilemma given the car is so new. I agree on the tires. I'd have gone after them straightaway, dynamic balancing all four.   Be sure the rear transmission mount is secure and tight.   Also be certain your exhaust system, from the manifold all the way back, is 100% tight, secure, and right. Be certain ALL muffler clamps are fully tightened.   You are describing what perhaps might be a harmonic vibration. Can you get it to happen just by revving the engine, or must the car be in motion?   Try driving the car in a lower gear and see if the more severe vibration happens at a lower speed. The objective is to see if the problem is connected purely to vehicle velocity, or connected instead to engine RPMs.   Report results/outcomes, if any, to your tech/service person.   Good luck!

Replying to: wlppete (Mar 05, 2006 5:54 am) I just purchased a 2000 Grand Marquis and, while I didn't notice it for the first couple of weeks, it seems to be doing it now. I'm experiencing a very similar problem to what you've described. I'm feeling a thunking noise through the gas pedal/firewall. It only seems to occur when the car is moving in excess of 60km/hr (roughly 40mph) and is most noticeable on a particularly smooth road. The thunking doesn't seem to occur at the same time as any bumps I might go over, it's totally independent of whatever I might feel through the tires.   The car is a really sweet one owner car that had 77,000kms on it. I got it for $11K CDN and it still has 2000kms (about 2 months driving for me) to go on a factory extended warranty purchased by the previous owner.   I've prowled the 'Net but I haven't found anyone describing the same problem who has found a solution.

Replying to: cyberwiz (Mar 14, 2006 7:29 am) If the vibration occurs when you accelerate slightly above 40 mph, you might discern when the oil was changed in the torque converter and transmission.   A "transmission service" cured the vibration for me.

Replying to: euphonium (Mar 14, 2006 10:52 am) He is talking about the "transmission shudder" - normally fresh Mercron V fixes it.   Do not let a mechanic tell you the torque converter is bad - it almost never is. Fresh tranny fluid, including draining the torque converter, will fix it.   Assuming that is the problem.

Replying to: cyberwiz (Mar 14, 2006 7:29 am) Really sounds like a damaged motor mount

Replying to: cyberwiz (Mar 14, 2006 7:29 am) I have a similar problem on my 2003 Crown Vic and 2004 Mercury Monterey minivan. I feel reasonably certain it is the Goodyear tires I have on them. On both vehicles, the tires need rebalancing after about 3000 miles. Always, the balancing weight position has shifted. The LM dealer eventually decided that one of the tires on the Monterey was bad and after replacement, found a very noticeable improvement but at least one other tire needs replacing. Neither the dealer or NTB tire store has found anything wrong on the CV but NTB advises that I should replace the Goodyears with a different brand. All four Goodyears on my previous 1999 MGM failed around 32000 miles - belt slippage.
#16 of 87 transmission problem w/ '02 Crown Vic by crownvic2 Apr 29, 2006 (7:55 pm)
I need to know what thw problem is when I accelerate from a light, slowly step on the gas, then speed up. The car almost studders then goes. It seems like the trans is slipping. Took it to the dealer and they said there was a recall on the problem, but they never fixed it. It has been back 4 times. Any ideas so I can help the dealer with what they should already know?

Replying to: crownvic2 (Apr 29, 2006 7:55 pm) No disrespect intended. And I'm not trying to be a "wise guy".   Honest.   But have you considered taking the car to a different dealer? That's what I would do. Your present dealer sounds like a snake.   And I mean no disrespect to snakes, either.
