Replying to: whitebread64 (Nov 24, 2006 9:08 pm) Having experienced the "shudder" - it is recommended you change the oil in the transmission and torque converter. You should then be good for another 40,000.

Replying to: whitebread64 (Nov 24, 2006 9:08 pm) 14 quarts of Mercron V transmission fluid - make sure they drain or pump out the fluid in the torque converter. I think the 2001's still have a drain plug in the torque converter. If you don't have a drain plug, the mechanic might have to disconnect a line at the transmission cooler and let it pump out. My opinion is to not "flush" the transmission, but drain the fluid, drop the pan and check for debris, clean the magnet, and change the transmission filter.   Labor might be a little higher, but if you use high quality fluid (like Amsoil), you should be good for another 100,000 miles.   This could be done by an average shadetree mechanic, but trying to remove 14 bolts from the transmission pan while on my back is no longer something I'd like to try.

Replying to: whitebread64 (Nov 24, 2006 9:08 pm) Have you had your spark plugs and especially your spark plug leads checked or changed? A spark plug lead which breaks down can cause the engine to miss and the car to chug, jerk, or jolt. Sometimes this engine miss from a faulty spark plug lead happens under light acceleration rather heavy acceleration. Two or more bad spark plug leads can cause the car to really jerk, chuck, etc. Fouled spark plugs can cause the car to jerk, chug, etc.

#43 of 87 '91 CV LTD wagon tranni(?) problem-lady needs help by teachinjose Aug 11, 2007 (1:44 am)
Hi everyone,   I inherited my father's '91 CV wagon, LTD, w the 5.0 and it's been great, but the tranni has been whirring at about 40 mph for the last 2 yrs. or so. To compensate, I start in overdrive, 0 to 40, hear the whir, switch to drive, then accelerate to 60, when I can get back into OD again to save gas. If I don't do this, the trani makes this slipping sound and the car hesitates. I switch the gears cuz I don't want to wreck the transmission. ( I had an '85 Buick Cent. T that took 6 rebuilt tranis,(GM 440's), but got 185K miles out of it.) Any ideas on how to fix this? Thanks. Teacher in San Jose

yes i have a 97 vic. and sometimes when i excelerate the engine revs for a few second then it will shift. what could the problem be and how and how much does it cost to fix Replies to this message: euphonium (Aug 31, 2007 10:13 am) jsylvester (Sep 01, 2007 6:20 am) captain131 (Sep 14, 2007 2:34 pm) bestracer500 (Jan 26, 2008 7:19 pm) teachinjose (Sep 15, 2007 7:31 pm)

Replying to: hyphy (Aug 30, 2007 6:05 pm) If you have over 40,000 or it has been 40,000 since, change the transmission oil including the turbine. If you plan to keep the car change to a semi synthetique, it's costly, but lasts longer and performs better. Mercon V is the one.

Replying to: hyphy (Aug 30, 2007 6:05 pm) It's hard to say - usually the sign that the transmission fluid is old is you will start to get "stuttering" when the transmission tries to shift into 4th gear. As mentioned above, it is the torque converter that gives you warning of that issue.   The poster above is correct in regards to the fluid to use - Mercron V is backwards compatible with all Grand Marquis back to 1992.   This is just my personal preference, but when I change the fluid, I drop the pan and change the filter as well - in my mind power flushing just forces all the dirt in the filter back into the transmission. That will also allow your mechanic to see how much trash is attached to the magnet in the pan, and whether there is something more serious to fix.

Replying to: jsylvester (Sep 01, 2007 6:20 am) Hi Folks, I have a 99 Grand Marquis that has had major issues, but only has 44K miles on the engine. I should preface this that my mother bought it back in 2001 with 21K miles on it. She knows nothing about cars, and the ford dealer at the time took advantage of her (IMHO). She never did a carfax (not that she would know what that is) on it, but I have since. It was originally owned by a "major car agency" (I believe that's speak for a rental) in Virginia. They shipped it to MA and she bought it. Over $6,000 later (not including the cost of the car) I have had numerous issues.   I have an extremely trustworthy mechanic and excellent diagnostician when it comes to cars of all makes - but this one has stumped him for the past 4 months. We had a total of 21 bad codes on the computer and after taking things apart we found evidence of salt water corrosion. Anywho, the car would drive at any speed and suddenly shut off - very dangerous. He was able to fix that. Down to one last problem - could use your thoughts:   When driving in OD, usually b/w 30 and 60 MPH, the car shutters a bit and the trac control light comes on. It happens occasionally when I'm driving with the OD off, but very infrequently. My mechanic has replaced every module and computer and bypassed wiring harnesses with clean, direct connections, to no avail. He brought it to a local Ford dealer, explained the situation, and they were at a loss as well. They mutually decided to replace (I believe) the traction control/ABS (?) module and reflash the computer. Still no joy.   Any thoughts? I'm thinking it's a tranny issue, but he already flushed and filled with Merkon V. He has gotten to the point where he has stopped charging me any labor, but that always puts me on the back burner when it comes to him fixing cars. I don't want to go somewhere else and start over again, and I certainly am not interested in going to Ford dealer as they seem to not give a crap.   Any thoughts, ideas, suggestions ???? Please - If this car had theft on it I'd actually consider drastic measures.... Replies to this message: bestracer500 (Jan 26, 2008 7:19 pm)
#48 of 87 '91 CV LTD wagon. Is Mercron backwards by teachinjose Sep 15, 2007 (7:31 pm)
Replying to: jsylvester (Sep 01, 2007 6:20 am) compatible w that car, too? I bot over $200 worth of Amsoil fluids and want to make sure they're okay for my old "tuna boat". The factory rep said they wear.   Also, do you think it's rational to want to keep the ol' girl running? The engine is strong,5.0L/150 hp, and it needs about $1500 in body work. Interior's very clean. This is the most comfortable riding car I've ever had, and I'd like to drive it for a couple of decades more, maybe even past that!   Thanks for all the tips.
