toyota 7FBEST15 drive fault?

Our toyota 7FBEST15 has a drive fault. there is no fault codes. when driving forward or reversing the truck starts to shudder (shake)
i was thinking along the lines of accelorater pot or maybe the speed bearing?? any ideas? has any one else had this?

Hello

Is this unit an SC2000 or an newer type
Perhaps you need to callibrate you pot but than you need an callibrator for the SC2000.
It happens more.

Is this unit a 3 Wheel unit?? If so, here in Canada we have seen allot of gear box inner bearing or planetary gears bearings go faulty due to heat exposer to long runs. Check/Drain fluid look for contaminates ( Bits and pieces) Change fluid every P.M. with ATF Dexron 3 instead of gear oil. If its a 3 Wheeler????

it's the same with the truck jacked up. the wheels juder. i'm getting the correct voltage to the accelerator pot. i'm just wondering if its the speed bearing in the motor or would that bring up a code? might need the handheld on this one.

Try jacking the truck up and see if it runs smoothly jacked up? Try work out if its a mechanical fault or load related. Had a judder problem on a Hyster once wheel was jamming/locking up.

Fact of the week
Bluetooth is named after the 10th-century Viking king, Harald Bluetooth, who united warring tribes in Denmark and Norway. In 1997, Jim Kardach from Intel gave the name to the technology because of its ability to unite different communication protocols, just as Harald united various tribes.
