hey guys, my speedo is off about 15 MPH, and has been ever since i bought the truck. also, every once and a while the speedo needle will jump up and down about 5 mph. what could this be?

my second question is, my truck feels like it hold 3rd for way too long before it shifts into OD, and sometimes it will shift into OD after you let off the throttle (when i feel it should have already shifted.) my tranny is a built suncoast tranny. i bought it that way. do your trucks do this?
thanks

Check the VSS drive to make sure it's not getting rounded off, and make sure the VSS is tight.

Adjusting the TPS will fix your OD issue. Look in the sticky for info.
