    Condition

    Some customers may comment on the following conditions:

    • A hesitation, sag or lack of engine response while accelerating. This typically occurs after backing off the throttle then shortly stepping back in to a heavy or wide open throttle position. This condition may occur at any speed, but is most likely to occur after accelerating to 48 to 80 km/h (30 to 50 mph), backing off the throttle then stepping back in. A 1.5 to 2.5 second delay may occur before the vehicle resumes acceleration.
    • Frequent transmission shift cycling occurring on slight to moderate grades when in cruise control at vehicle speeds from 64 to 121 km/h (40 to 75 mph). The customer comment may include "too much vehicle speed variation from the desired cruise control speed setting" when the shift cycling is evident.
    • On the initial cold startup when ambient temperatures are below -22° C (-8° F) and an engine block heater is not used, the engine starts and may immediately stall. The engine will typically restart immediately and operate normally.
    Correction

    A revised transmission calibration has been developed to address these issues. Reprogram the transmission control module (TCM) with an updated software calibration. This new service calibration will be released with TIS satellite data update version 8.0 or later, available August 14, 2006. As always, make sure your Tech 2® is updated with the latest software version.
    After reprogramming the TCM, Service Fast Learn Adapts must be performed using the Tech 2®. Check and clear all DTCs that may have set as a result of the programming process .

    Re: 2007 Escalade Tranmission TSB (Two of them)

    I'm new to this site but i need some help. I have a 2007 Cadillac Escalade that has hard shifts when up shifting and down shifting. sometimes it feels as if i got hit from the back. when i let off the gas then back on it kicks into gear rough. When i'm on the highway its perfect no problem at a steady speed or even between the higher gears. sometimes it has a rough idle but it goes and comes as it pleases. there is no check engine light on and i have no mods done to it. OEM wheels and tires. can someone help me.

    Hello steven2014,

    Welcome to the forum! I am sorry to hear that you are experiencing rough shifting and idling with your Escalade. Have you been in contact with your local Cadillac dealership regarding this matter? Unfortunately, as I am not a certified technician I am unable to provide technical advice regarding your concerns; however, I would be happy to put you in contact with the Customer Experience Manager at your preferred dealership. If this is something you would like my assistance with, please send me a private message with your full contact information, VIN, current mileage, and involved dealership.

    Sincerely,

    Jonathan A.

    I have a 2006 Escalade with similar problem. I was traveling on the highway at speeds of 50 - 70 and experienced shifting in and out of overdrive ( a lot of shifting) the check enging light is on, I don't know what the code is, but when I asked a mechanic to read it, he said it was a code for a vacuum leak. We had problem with gas cap and replaced it a couple of years ago. I thought it may be that again.
