just wondering what these sonex kits are all about? i have seen some posts any way i have a 97 f250 psd and the e40d tranny is acting up. any info would be great
Sonnex kit will firm up the shift points, which is easier on the transmission. How many miles do you have on your truck, and what is it doing? I agree a sonnex kit will not fix a tranny. Jcab

truck has 168000 miles i live in minnesota and its getting colder the truck seems to take a lot longer to shift . and some times it wont shift to od unless i stop and try again.
WHEN WAS THE LAST OIL AND FILTER CHANGE ON YOUR TRUCK, CHECK COLOR AND SMELL OF OIL WHEN CHANGING. AND ARE THERE ALOT OF METAL PIECES ON MAGNET ON THE PAN. MIGHT BE A VSS SENSOR MOUNTED ON THE REAR DIFFERENTIAL. JCAB
