I'm not a mechanic either, but one possibility is a broken accumulator spring. These, among other things, help determine the firmness of a shift. If a spring breaks then it could affect your shift like you are describing.
It's a medium difficulty fix, messy and moderately difficulty to get...
I don't know if you're looking at this the right way.
Are you assuming a "Ram Air" concept? As in the car moving through the air creates a higher pressure? If so, then that's bunk.
Cold air is just that...cold air, which has more oxygen per volume unit and makes more power. I hope this is...
Sounds like it was just a lemon. Rear ends are pretty standard, lo-tech systems and shouldn't ever have problems if they are set up right at the factory. Yeah, it's good you had a warranty.
Changed it....or had the supermod change it. I used to be tbird9768 on everything. Then I sold my 68 Thunderbird a couple years ago and then I'm making a half-ars'd effort to sell my supercharged 97 'bird...and I used to go by Grasshopper on my college intramural softball team. Long legs to beat...
I had to replace a coil and a couple other things on my 95 Ford truck a while back, to the tune of almost 600 bones. gah! But that wasn't something that I knew how to fix, so oh well...
I dig your sig, 4x4. hehe. Toyota payin' ya? LOL!
Not necessarily true...
I've been running a K&N in my Thunderbird (supercharged) for about 8 years and in our Expedition for about 4 years. I've properly oiled them and cleaned the MAF's when needed.
In fact, I'd hesitate to use some other brands of filters due to bad construction. K&N...
Look at my sig....
I run an Allen supercharger on my Thunderbird and they make them for the trucks.
I think Green runs a centrifugal blower. Vortech???
It's not gonna pick up a lot of HP. It might sound a little different and you might subjectively have a seat-of-the-pants gain, but they work better if you have forced induction and headers/exhaust.
Ummm...on this big of a truck, I'd spend more money...
On the uneven wear, make sure you use the brake pad goop (sorry, don't know the technical term). I had this problem on the front the last time I did them. The pad to caliper contact was dry and not straight. After re-doing the job with...
Thanks for the info on Mercon/Mercon V. I have about 18-20 quarts of Mercon in my garage, so I'll be using that the next time a fluid change is in order...which should be soon. (Don the hazmat suit!!!!)
I forgot...What I do when it's all empty is fill it with about 6 quarts. Turn on the car...
I don't know which is easier, but another way to almost completely flush the system is to drop the pan (take a red bath!) and then drain the torque converter. I have the same setup you do and mine has a TC drain plug. It takes a while to drain but it might be easier for you to do it that way...
That has always been the case with both our 5.4L and the 4.6 in my Thunderbird. 'Tis normal, like it was said before. If it bugs you, check your level every few weeks and add if needed.
I've always added 6 qts with no issues, just like the manual says.
