  1. So, I really don't want to drail the intent of this thread. However, I will very briefly comment. Any of our RWD based trucks that have 2 spd tcases (which have a neutral state) are "supposed to be" dinghy towable. You bring to light, the lack of info out there on the 2500 series trucks in the owners manual. (1500/3500 series have sections in the owners manual specifying what models can be towed) I am working with the tcase and owners manual group on updating the information. I'd expect we would release a bulletin as a supplemental to the owners manuals (short term) with the additional info so dealers can share with customers who inquire. I will try to let you know when this happens. Please wait to do so, as this would be the documentation you require stating that a 2500 series is towable.
  2. I don't have much to share. The info I've seen so far, supports what I expected for answers. I'm highly confident that our testing standards ensure that we met and exceeded customer expectations with regards to transmission specific dinghy towing durability. I've compiled some of the data. I'll have to revisit it, recompile and potentially post a plot of the info sometime in the future.
  3. When you turn the key and put the ignition in the accessory position, it can drain the battery over time. Removing the DLIS fuse, when towing, removes the power to the BCM causing the ignition relay to open which stops the battery from going dead. Hard to say if in 200-350 miles the battery would drain the battery too much.
  4. Does it sway when making a turn or as you are driving straight down the road?
  5. Your Saturn should be equipped with the the larger 6spd auto, the 6T70. It is towable.
  6. Special thanks to all of you for taking the time to give me some feedback.
  7. Can you tell me what engine and trans you have in your Lucerne? I may be able to find that info.
  8. What engine/transmission is in your Saturn and what model is it?
  9. Thank you for all the feedback provided to date! Very useful to ensure we are aligned with customer expectations.
  10. My name is Nick. I work on the new 6T30/40/45/50 fwd 6 speeds at General Motors within transmission development. In particular, I'm in charge of validation for dinghy towing. I'm after some feedback, regardless of vehicle make, about the vehicle you currently dinghy tow (or have towed in the past). 1. How many miles do you typically dinghy tow your vehicle yearly? 2. What is the total tow mileage you have on your vehicle now? 3. What is the total tow mileage you expect to put on the vehicle before you upgrade to a new vehicle? 4. When towing, what is the average amount of time between stops? (be it restroom or fuel)? 5. How often do you stop for a period of 10 min or more? (be it restroom, stretch, eat, fuel)? 6. What is your preferred cruising speed? 7. Do you use a rock shield? 8. Where does the rock shield mount (bumper,towbar,dinghy, or... so what type)? Your feedback would be greatly appreciated, which will help me better tune our internal testing requirements to better meet and exceed actual customer usage.
