What exactly is this TSB all about, and is it mandatory? When was it issued?Before having TSB 05-002/20 applied, I would most often and routinely encounter it in turns, especially right turns--brake going into the turn. RPMs drop, then lug as I accelerate out of the turn. Also from a stop at a traffic light where accelerating then letting off the gas when realizing the guy in front is lollygagging, then reaccelerating. In short, 2nd. gear failing to drop to 1st. or 3rd. gear failing to drop to second.
That's in routine driving. In sport mode, or just zoom-zooming around, the RPMs wouldn't drop low enough to get the lug.
This was my #1 issue with the vehicle without a close second. Given the number of posts I've made on the subject you can it is my #1 obsession. The TSB has all but eliminated the lugs even though the TSB description does not address this problem.
My experience seems somewhat unique among normally aspirated 2.5L owners. I think more folks have complained about jolts into gear than lugs and some who have had the TSB applied see no difference. This is hard to account for. Perhaps the TSB is a patch not a re-flash of the entire PCM with different years or AWD vs. FWD having different base code. Or the performance adjustments that are stored don't get cleared out when the software update is applied. Or maybe the dealer blew it off in some cases--they probably don't make any money doing TSBs.
It occurs to me now that if the TSB doesn't yield any difference, maybe disconnecting and reconnecting the battery might do some good--just a wild guess not knowing what the TSB does or the procedure for applying it.
Also, does it apply to all models, or just the CX-5?
Thanks.
