1999 Chevrolet Blazer LT review from North America

Unfortunately, I must report that this little truck has just cost me a new transmission. Also, about two months ago, the steering column was opened up to replace the complete control module unit that includes the multi-function lever and emergency flasher button. Failure of this unit resulted in an intermittent, yet frequent ticking from the flasher module under the right side of the dashboard. Imagine the sound of the turn signal ticking away for sometimes an hour straight without the lever being clicked on.

I wish to impress upon owners of similar vehicles with the 4L60E automatic transmission that the problem originates in a faulty valve body causing hard shifting from first to second gear. The engine light comes on, and code P1870 will be rendered upon performing a diagnostic scan. At this point the friction material on the lock-up portion of the torque converter is mostly burnt away. Also, within the transmission body, the improperly hardened sun-shell gear teeth have begun to grind themselves smooth. This will now cost you a complete rebuild. Smile while GM and it's dealers denounce any knowledge of this common condition, as they suggest that the problem may lie within the driver and/or lack of maintenance. Otherwise, this is peppy luxury sport-utility that achieves acceptable fuel economy, gobbles the snow like candy, and starts in any weather thus far.
