Driven, I will let you know...mine will be reprogrammed tomorrow at Dealer. I have 49,200 miles so sneaking this in under original warranty.

Joe 2006 4.4

i get this when i am driving in D mode.....however when i change to S mode I dont get them.

Yep, same here. I don't get the slam on acceleration though. Mine only does it right before the vehicle comes to a stop. DS mode takes care of the issue. I have also heard other report that this happens more frequently after you have been cruising for a while, such as the highway or any roads where speeds are fairly constant for a period of time. :dunno:

I dont get the lurch in S mode either

I tried this yesterday too and selecting sport made the issue go away. Although I suspect the 2nd to 1st change is just occurring at a slightly higher speed and thus not as noticeable.

I have also found that if try to keep the braking consistent all the way till I stop helps too. Before and what I usually I would do is ease up on the brake right before the car comes to a complete stop to make it as smooth as possible but this just makes the lurch/change down to first way more noticeable.

Interesting post guys, though nothing new unfortunately (for me, and others I'm sure!) it just seems to be the same old problem rearing its ugly head:popcorn:

I have the same issues myself with a 2001 4.4 euro (UK) model, the lurching when cold, particularly in 1st, which goes after about a mile, and the (extremely annoying making-it-look-as-though-its-your-crappy-driving) sudden change down into 1st from 2nd when slowing down, say, to round a bend, which ends up putting you and your passengers through the screen!:yikes:

I have tried the 'tranny reset' as found on this forum (pushing down the accelerator, ignition pos on/off for a certain time etc etc) to no avail.

Could the software update work for a 2001 model? I ask because I can only ever find posts about later models getting the upgrade-working for them or not.. Also, if it is possible how do I go about getting it done? Will it cost me if I don't have a warranty? If so, any idea on price?

Thanks guys,

Ian

I did the "REAL" adaptations set up and it did make it change gears better and smoother but took some time and patients! Didnt get rid of the Lurch!

It has to be a programming issue if switching to DS solves the issue for most people, right?

I would think so. The SIB describes the exact problems I have. However the dealer want $180 to reprogram the transmission with new software. They claim "It has to be plugged into the computer and programming takes about 4 hours."

Anyone able to shed some light on if new software will actually fix the problem?

I have a 2001 4.4 with shifting problems..Mine stays in a lower gear, longer before shifting up. At 75mph the Tach.is at about 3500 rpms and then after a bit it WILL up shift. This doesn't act up all the time for every shift though! I was on a 400 mile trip and it only acted up 5-6 times..
