He stated that unfortunately it has been his experience that this particular year Ford f150 has a history of poor transmission performance due to its very thin transmission gears. The truck has never been exposed to water other than what rain gathered on the road. The same dealership that fixed the problem lol stated that they fixed it and that they are not responsible for fixing it again, despite it only being three months ago. Took it to aamco and ran diagnostics. The engine speed increases but the vehicle does not accelerate.
And I will also add, if the fluid had been regularly serviced it might never have developed the shudder and servicing it might eliminate possible future problems. I just want to see if anyone has suggestions now, in case this is something bad. There were no warning indicators illuminated on the instrument panel. The owner had to keep the foot on the brake to keep it from rolling back. I hope they fix the problem the first time before it expires.
This applies to 2004 2005 2006 2007 and 2008 Ford F150 trucks. My rear seal recently had a leak where the rear driveshaft sonnects ot the tranny , but I have replaced it and all is well there now, or seems so. The service rep at my dealership says that he can't duplicate the problem. That would not be a rare thing. I personally would use motorcraft- or Accel-. But now it is doing it again.
Likewise, if I accelerate slightly more pressure on the gas , it will accelerate right up through the shudder range with no problems. So I guess the others need to be replaced. That would not be a rare thing. Other than the shudder, the truck runs perfectly. But now it is doing it again. In several poinst, while pulling on to highways, the transmission skips and and delivers too much power to the rear wheels, causing the tires to slip on wet pavement. The truck then developed a stall like it was low and gas and blew black smoke on cold starts and take-offs.
Also, my automatic transmission is slipping for the second time. The vehicle has not been diagnosed by the dealer. I did a tranny flush about 8k miles ago and it did not have any noticeable affect. Finally a light came on but the codes were nothing serious. Picture yourself driving a 50 mph.
Likewise, if I accelerate slightly more pressure on the gas , it will accelerate right up through the shudder range with no problems. Since I have had the truck the rearend has developed a loud whining sound and slung the rearend lube out and under the bed. I have 151K on truck and had plugs changed and tranny flushed around 105K. Cleaned that off and the problem went completely away. Besides, I hear that the 2004 F150 Plug replacement is a horror show due to the plugs being notorious for breaking. From looking online this appears to be a common problem that Ford is not aknowledging. I did a tranny flush about 8k miles ago and it did not have any noticeable affect.
The owner's manual indicated that the high fluid level could be and indication of having an overheating problem. Next a hum and then jerks in between shifts. Customer has a car that started instantly hot or cold, idled like a new sewing machine, ran like a top no matter how hard the acceleration was, etc. They seem uninterested in my problem and they have not fixed a damn thing since the board decision that it is fixed but it is worse and I told them it was worse personnally, the truck is a pile of poop and Ford knows it but because many of these trucks have the problems they are not willing to fix the problem. It is only when my speed drifts back and forth during the 45 - 55 mph zone that the problem is noticeable. A very common concern when the tc locks up. If I apply the brakes for a second and then go back to the gas, it accelerates normally.
I had the same exact problem with my 2006 f 150 4x4 with 130k + miles. Please assist with getting this problem fixed and some help is holding them responsible. Just 1 or do i need 2? While driving between 15-20 mph metallic grinding is coming from under the truck. The first 2 products are nearly identical and with some certainty I can say I have added them to hundreds of cars to correct your problem and other problems and as preventative maintenance when servicing the transmission and never seen any ill effects. The pads and rotors were replaced six times. Mechanic could not rebuild the transmission had to be replaced.
Reverse occasionally serves like the neutral gear, preventing vehicle from backing up. From talking to one of the service employees I learned that there have been many complaints about this problem. Cleaned that off and the problem went completely away. Other than the shudder, the truck runs perfectly. If I apply the brakes for a second and then go back to the gas, it accelerates normally. How many bottles do i need? How many bottles do i need? No problems noticed when my speed drifts down, but when it begins to drift back up, the truck shudders a bit.
