Towing with 6.2 & 3.42 gear ratio
I am curious what you are towing with your 1/2 tons with the 6.2 and 3.42 gear ratio. How does it do in the mountains? I know getting the 3.73 will be better but I am only towing about 6 to 8 times a year and only 1 or 2 times will be up into the Sierras. I will be towing a 23 foot toy hauler that will be max weight of 8,000 pounds, most of the time between 6,500 to 7,000.
Thanks in advance

What year/model is your truck? For the 1991 year which is pretty representative of the 90s bodystyle, the 6.2L diesel with 3.42 gears has a max front axle weight rating of 3400 and rear axle rating of 3968, and gross combination vehicle weight (GCVWR) of 10,000 pounds. Considering the truck weighs in at around 6000 pounds, that only gives you 4000 pounds of capacity. That said, the brakes are probably not strong enough to adequately stop that, and you will certainly need a weight distributing hitch. The engine and transmission are probably adequate on flat land, but not the mountains because of the low gear ratio. You'd need to ramp up to 4.10s or even 4.56s to drag 8000 pounds up the mountain.Christopher

Your not giving us much info to enable a proper answer; but, here is my 2 cents.
I have the 3.42 and the 5.3 I also have the tow/haul feature and a 6 speed tranny.
My advice: you have either the 4 speed, or the 6 speed tranny, just drop down a gear for the 4speed, or 2 gears for the 6speed and you will be fine.
If................you have a transmission fluid cooler.Ray
