is this in 4th gear at steady throttle?what if you use d3 on the hiway?

this is in forth gear. it will go into lockup but after driving a while it goes in and out and RPM's go up and down.

 

[chris718]

do you have a scan tool?

yes i forgot to mention that i have a caspers stand alone harness w/a VSS module. maybe there is something wrong with the VSS module.
