Mazda Repair: Mazda B4000 truck, mazda b4000, mazda dealer

Question
when my 2005 Mazda B4000 shifts into high gear (automatic Trans.) @ approximately 40 m.p.h. it starts surging, a slight bucking motion. It has done this since new. The Dealer say's nothing's wrong. Chris, it's driving me crazy. Any help is appreciated.

Answer
Hi John thanks for asking
It definitly sounds like you have an internal problem with the transmission, When you go to the Mazda dealer dont take NO for an answer, this vehicle is under warranty and this problem should be adreeses and looked after. Tell them to check for any PCM updates and tell them to test the transmssion properly, if they say no problem again, take it back agian and agian, they will do something then.
Let me know what happens
