Transmission Shudder
Hi everyone!
I just bought a 03 4.4i and it has some transmission problems. The first thing I noticed was that when driving at steady speed around 50mph the rpm slightly fluctuates. This doesn't happen when driving steady but faster 70 - 80mph. Then I realized that when driving around town, it shakes when changing from 3rd to 4th almost always. It goes away if I press the gas or if drived in manual mode. When happens it feels like driving through a bumby road. Do you have any idea how can I Fix this problem? Thanks! |

Try a couple of tubes of shudder fix. Amazon sells it. Probably the torque converter. Wouldn't hurt to try it. Sent from my iPhone using Tapatalk |
There's a flex plate between the driveshaft and transmission aka Guibo. Check the condition of that before wasting your money on shudder fix.

It could be a numbers of things. I would first look into the rubber driveshaft couplers. Perform a drop drain of the trans fluid. And these trucks are notorious for valve body issues.

Thanks very much guys, I will check the guibo and then I will try with shudder fix.

Had this problem myself and it is the lockup clutches in the torque converter.
Put somr Dr-Tranny in the box and it will clear up for a short time but that will confirm what i am saying. |
Thanks AlanGunn!
Did you fixed the problem? How much money aprox did it cost you? Thanks! |
I had a refurbished torque converter fitted with new filter and oil.
Cost me £470 but that was 3 years ago. No problem since and a nice smother gear change as well. |
