Thats something that would have to be checked by the owners of the SC'd and non SC'd bonnies...
I believe that there is a converter size diffrence between the MN3 and M15... For some reason I was thinking that the M15 was the AWD version... I'm a little lost on the AWD version...

I'll reconfirm, all 97 models with the L36 got the 4T60.....
Again, is there any possibility that this problem is exacerbated by high heat conditions? I don't want to get something fixed that isn't the true source of the problem.

I can't say for sure, but I'd do the test on a hot tranny (while the problem is occuring) and see what the results are.
TO VERIFY THE ABOVE CONDITION, PERFORM THE FOLLOWING TEST: DUPLICATE THE CONDITION AND NOTE THE TCC SLIP ON THE TECH II. THE SLIP WILL RANGE BETWEEN 50-150 RPM. NEXT, COMMAND THE TCC ON WITH THE TECH II. THE DUTY CYCLE SHOULD READ 99% AND THE VEHICLE SURGING CONDITION SHOULD NO LONGER BE EVIDENT. IF THE ABOVE TWO (2) PARAMETERS ARE MET..........SEE THE FIRST POST ON THIS TOPIC FOR RECOMMENDED REPAIR.

So either I need to take ol' Bonnie to the dealership or buy myself a Tech II? Hmmm... I'll opt for the former, lol.
How labor-intensive is this fix for a dealership? Is this a "pull the tranny and disassemble it" kind of deal, or a relatively simple task? Translated: Will this cost me my firstborn?

Well the bulletin says the job pays 3.5 hours under warranty, so you can use that to negotiate but they will probably try selling it for about 5 hours. The control vavle body is probably between 150-300?

hrm.
replacing the valve body... that'* not something I think too many peeps here are interested in doing. expensive... very expensive. unless you do it yourself.
anyway, seems like this should be covered for everyone, as it'* obviously a problem we *all* have.
then again, so'* the upper intake, so...
