I have a concern with the transmission's on the Mazda 626 transmission style cd4e. There are thousands of people (internet searched) who have these vehicles and have been placed in dire straits as I am. I was traveling down the freeway at 65 mph and from out of nowhere, my od stopped functioning and left the car's tranny slipping out of 4th gear searching for a lower gear as it threw the flashing "od light off" indicator light. I had a woman swerve behind me as I had total loss of power and trying to get my car to grasp any gear. Once I pulled to the side of the road and stopped, the od light stopped flashing and my vehicle was left in a "limp home" mode where I could not get over 45mph. I had the tranny rebuilt to the tune of 1500. 00 and guess what? I got into the car to do highway travel one week later, and it happened again. I have read that I am by far the only person this has happened to. This is a 2000 model. My brother bought it in 2002. He has maintained the vehicle for the last 7. 5 years and I have had it for 6 months now. The miles are 76k, only! someone needs to have Mazda fix this issue. This is rediculous and thie is by far a major safety concern. The surging and searching the 4th gear does is very hard, jerky and surging. Anyone right on your butt in traffic is going to slam into one of these vehicles. There is also a TSB for this as well. . . . . . But Mazda has offered no amends to this situaution when I called the customer service line. They said they were unaware of this situation. That is simply not possible.
