Software Update

[gtbigup01]

So, I purchased my truck 17 SLT CC 5.3 (8-spd) 12 July and have since put 10,3xx miles on it. On my first day of purchase I experienced the transmission clunk and didn’t think much of it. However, during my 55.5 miles daily commute to work, of which about 43 miles of that is interstate (i24) and daily stop and go, I start to notice this issue even more. Sometime I actually have to look in my rear view mirror to see if someone bumped me due to jolt from the shift/clunk during crawl speeds. Well on my second oil change last Saturday, I addressed the issue, however the “transmission guy” apparently don’t work weekends, no problem. Monday, I made an appointment for during the week and had an appointment last Friday. While making the appointment, I made sure to let my service writer know that I’m aware there’s no permanent fix for this but some folks had luck with the software update.

 Well I’m happy to report that though not completely cured, it’s 95% better shifting that it previously did. Ticket stated; Updated TCM per 16-na-404. So any of you that have this issue, don’t expect a complete cure but there is a chance the update may do your transmission some justice.
