UPDATE: TSB 11-2-2 for "WHITE SMOKE IN DAMP WEATHER CONDITIONS WHEN ACCELERATING"

[PSDfreak]

This TSB supersedes TSB 8-25-1

Went to the dealer this morning because my truck hesitated again while accelerating in the rain. We found a new TSB dated Feb 2011 with a NEW cac part number.

Cac is on order and will be installed tomorrow.

Figured many others could benefit from this info.

Is it a new design cooler and did it work?

Is this covered by warranty? Just bumper to bumper?

Went to the shop today for 40k maintenance. Gave the TSB to the advisor. They said they couldn't do anything unless they could reproduce the problem. So they wanted me to bring it in when its raining!! Like I have nothing else to do. How can I get this performed? Try another dealer?

I have had this exact issue happen just like the TSB states at least 4 times.

This is a new cooler and so far seems to have cured the problem for me.

They are technically supposed to "reproduce" the symptom, but it you get a good service department they'll do it for you, try somewhere else.

I'd check other dealers. How many times have you had it in the shop for that problem.I had mine in at least 10 times in the last 18 months and got it changed last week.. Will find out this weekend if it solved the problem. Good luck.

any updates? my 08 job 1 started diong this noticably yesterday. researched and found updated (feb 11) TSB 11-2-2 that rplaces CAC with part # 7C3Z-6K775-C

Had mine changed 2 weeks ago. Drove 500 miles last weekend and didn't have any trouble. Maybe it is finally fixed. There is also a PCM update on customer service program 11B23 now available. I don't know if it is for all 6.4's.

thanks. looking into this it is covered under new truck warranty and emmisions warranty. mine is going to be headed to dealer soon for a couple emmissions issues- exhaust leak near turbo and now hesitation and possible update reader on pcm........ still love this truck tho!
