I would not worry about it. There are litteraly millions of these trans on the road in GM Trucks and many of them last 200,000+.
If you plan to tow, either add an external cooler (stacked plate) or upgrade the one you have considering where you live. Service the trans, I recommend syn fluid. Add a trans temp gauge like the Aeroforce Interceptor, tow in 3rd with the T/H engaged and enjoy your truck.
You need to research max TT length for your Tahoe. Their shorter wheelbase does limit your trailer length.
Good to know about the TT length, thanks.
As for the reliability of this tranny, what you're saying is the impression I'm starting to get after "wasting" this whole weekend reading this board.
At first I read enough to make me nervous, but the more I read, the more I'm comfortable with it. In fact, I'm pretty much ready to order a tune from wait4me. I'm now convinced the tranny will be fine.
I do have 4.10 gears and the factory HD aux trans cooler. I don't know what the quality of that one is though.
I don't remember the context of the post, but I remember someone here telling a guy his tranny already comes with synthetic. When did that start? Mine might already be synthetic?
Mike,
I can help you with your questions.
Your truck does not have syn fluid. GM began using Dex VI in late 06 if I am correct but I know they were not using it in 05.
Your OE cooler is a stacked plate designed cooler and is an excellent overall cooler. IMO it is too small for high heat climates such as the Southern parts of the US. This is why I upgraded mine to an 11 x 11 x 3/4 unit. Your is apprx 5" x 11" x 3/4". I will be happy to send you some pics of mine installed in case you consider upgrading. I would need you to send me your e mail address in a Private Message.
If you have the 4.10 gears you will be pleased with the towing capacity of your truck. You will want to use 3rd with the TH mode. This will keep your Revs right in the 5.3's sweet (2300 to 2800) spot when you are driving between 55 and 65. If you get a tune, be sure you tell them you are towing and are looking for extra tq in the low to mid range. More HP and TQ at 5500 RPMs is not going to help you tug that camper.
