#1 of 19 does your cougar buck?
Apr 06, 2008 (4:10 pm)
we just got a 2000 cougar v-6 automatic we really like it but when it is warmed up and traveling about 50-55 it sort of bucks then stops then a bit later bucks again. I call it bucking because i am not sure if it is hard shifting or severe hesitation. has anyone had this problem or know of it???

I know exactly what your talking about and we have been dealing with this since last fall. I was curious if you were able to get this problem fixed? We are taking ours back today after 3 previous trips to the garage. We saw there was a recall that has to do with the fuel pump so we're hoping this is it. Our 2000 Cougar gets to the same speed as yours and does the same thing. I hope your have had good luck with yours.

This seems to be a common problem with older 99 and 00 models from what I''ve been able to find online. There''s a discussion about it in this forum:
What does NOT seem to fix the problem is:
New spark plugs, fuel filter, carbon cleanout, new EGR valve
What DOES seem to fix the problem is:
New temperature sensor (you need to get this directly from Ford but the model for the Contour looks to be compatible), MLP (mass lever position) switch, and/or the Mass Air Flow sensor. The parts appear to be cheap, but the labor can add up to a decent amount. Hope this is helpful.

We went through this with a '01 cougar - after EVERY sensor change, new coil pack, plugs, etc. Shop finally hooked up a fuel pressure gauge and took it for a drive, when engine fully loaded, like hard accel at freeway on ramp or long hill, pressure would drop off, intermittently. Fix was a fuel pump the one int eh tank !). Thankfully, the shp was NOT charging us fo rhte repeated returns for same item, though we did meet them half way with parts - at leas tall new sensors. Been fine since.
#5 of 19 cougar transmission choice
Sep 10, 2009 (8:32 am)
I have a 95' Mercury Cougar XR-7, V8, 4.6L RWD and it needs a new transsmission. i was wondering if I could give it a 5-speed manual, instead of a 4-speed automatic like it had before? Is it possible to do that? If so, would the dealership do it, or do I have to find some tranny machanic? Please reply ASAP with any thoughts that might help!
#6 of 19 2000 Cougar auto trans
Oct 05, 2009 (11:22 am)
big YES to this problem -- to me seems related to being warmed up - 10 mi plus ride , doesn't do it just going to work in morning.---
going steady 70 mph , every 4 or 5 mi. , car will jerk / shutter , the engine tach will jump from about 2800 to 4000 rpm, sometimes even 5000 - like the trans can't select correct gear . . . .usually will be fine for 3 or 4 mile, then jerk 2 + times ,HARD jerks, then be OK again for a bit. after a longish drive , will even do it at slower speeds , so -- is this related to warm up ??? not warm weather but engine /trans heat ? the engine gauge stays 'N' . . . does the transm. oil cooler have a thermostat or some such ?
new fuel filter. new trans oil, took it too 2 shops didn't find anything. even tried unplug, wait an hour , re plug main battery ( owners man. says the engine computer will relearn.?) note there are 2 service notes about ' reprograming Auto trans control module . . .

I have a 2000 Mercury Cougar, and about a year ago it was doing the exact same thing. It couldn't decide what gear to be in and would jump around. Really difficult to drive. It ended up being the transmission sensor. I took it to a transmission place that knew what they were doing so it wasn't too expensive to fix. A couple hundred bucks if I remember correctly. I hope this helps. Seeing that you posted this a few months ago, hopefully you already have it figured out. If not, you should definitely have that checked out.
#8 of 19 Transmission shift problems
Feb 28, 2010 (4:52 pm)
Does anyone have a 95 cougar with an automatic trans and a 4.6 V8 that does not want to shift from 3rd to 4th gear unless you are traveling above 40mph?

to answer my own question from October - cruising steady speed ( 50 - 70 ) after 10 miles or so - engine tach would jump 1000, car would jerk , then back to 'normal' .... like transm didn't know what gear to be in ( 60,000 miles) -- after a winter of tip toeing around, afraid to drive more than 7 or 8 miles -- found answer ( OK, Ford dealer ) -- part only $ 80., labor 200 . > called : transmission range sensor 6L8Z 7F 293
drove it 40 mi right after repair, no problem, first time drive more than 10 mi, no prob. since Aug. ... today , drove 90 miles non stop, most at steady 60 , no problem.
Why the Merc dealer I bought car from new couldn't fix 6 months ago ... ?
#10 of 19 speed sensor
Jun 10, 2010 (5:46 pm)
hi im new to this. i got a 99 mercury cougar. 2.5 V6 DOHC. my speed sensor crapped out so i got a new one from Advance Auto Parts. Problem is the sensor they sent me is too big. It looks exactly like the stock sensor, even has the same plug but the diameter of the sensor is bigger than whats on the car. Are there 2 different size speed sensors? Does the 4 cylinder have a small sensor? Help!!!
