Thanks for the lookup and info! Yo get a peppermint puff for that! Will double check the tacho at 55 and let you know. So all in all, do ya think its a good truck?
Of course I think it's a good truck, but I don't know that it's setup for what you really want. I wouldn't be afraid to drive the wheels off it
If you can drive manual, a 5speed swap would be great for towing, simply because of the overdrive and the C6 automatic robs some power.
I don't think you personally really feel like messing with that though, so I'd ask around about if upgrading the torque converter would help. It would be pricey, but might be a good investment.
When @Dieselcrawler looks at it, make sure there's a secondary transmission cooler! The C6 is tough, but likes to make heat while towing.
I know NOTHING about how it all works on that transmission, but I'm wondering if the kickdown and everything is working properly.
If you can track down a used turbo it will help tremendously, so don't forget to keep an eye out for one. Should be easy will all that dental office money (yes, I'm being sarcastic!)
