and after it taking almost 2 quarts before being full, I realized I may of made a mistake. I was changing it on the driveway (level) and since my h3 has not had the torsion bars tightened up, the front is alot lower than rear, allowing the t case to take more dexron-VI than normal (as opposed to being on a hoist). So I got out a jack and lifted the front end until a level on rocker panel/frame rail said it was level and then put plug back in. Did anyone else do this, or would a little more than normal in there not hurt anything? FYI, my wife now thinks I am borderline OCD, LOL.

 

I don't think it woulda hurt it, from what I remember it takes almost 2 qt's anyways. But to be honest I'm OCD about that stuff with my rig too so I probably would have done the same.

 

I dont think the instruction book calls for leveling b4 changing fluids, nor do they say you need to jack it up. so you are pretty safe doing a stock change on a stock truck, on a level surface. i doubt that you could measure the difference in the fluid.

 

My thinking is whenever a professional mechanic would do this, the h3 would probably be on a hoist and close to level. I don't remember my dealership having a pit in it's bays and I doubt they'd just crawl under like I did. I put a clean coffee can under the fill hole to catch what come out when I made it level (in case I over shot too), and the amount was about 3/4 of a soda can (approx 8 ounces).

 

Just for future info. 08 and 09 H3/H3T manuals say T-case capacities are 1.6 Quarts (1.5L for you Canadians and such) of Manual Transmission Fluid.

i guess some dealer may have a lift that grabbed the frame while another could have a drive on lift,leveling the wheels. i doubt if they would be concerned by the small difference.
a little over/under is not a big deal.

 

Are you sure? I'm pretty sure 06 and 07 are DEX-III, 08 and 09 are Dex-VI ATF.....

Here is a piece of info I have.

Transfer Case....MAKE SURE TO READ THIS CAREFULLY FOR CORRECT FILL LEVEL and RECOMMENDED FLUID. THERE ARE DIFFERENT FILL LEVELS AND DIFFERENT FLUIDS
Approximate capacities (see below) 1.5 liters/1.6 quarts

Again, recommended to raise or make sure vehicle is level.
Remove the drain plug and allow the t/case to drain.
After draining fluid, install pipe sealant to the drain plug and torque to 18 lb ft or 25 N.m.
Remove the t/case fill plug, and fill to bottom of fill plug hole:
2006 and 2007 Model Year Vehicles use manual transmission and transfer case fluid
2008+ Model Year Vehicles use Dexron VI trans fluid.

Apply pipe sealant to fill plug and torque to 18 lb ft or 25 N.m.
NOW, for all 2006 Model Year Vehicles and for 2007 model year vehicles if the VIN is 56TDN13E778100102 or prior:
Remove the speed sensor connector (top rear of t/case), then remove the speed sensor.
Add 250 ml (8.45 oz) of manual transmission and transfer case fluid through the speed sensor hole.
Install the speed sensor and tighten to 13 lb ft or 17 N·m. Then install the speed sensor connector to the speed sensor.
This additional fluid is needed.

Adding fluid into the speed sensor hole is not required for 2007 vehicles built after 56TDN13E778100102 or 2008 vehicles.

 

My owners manual said Dexron VI (1.6 qt) so that is what I used. The best fluid I could find was Castrol synthetic blend. It was actually not too much work so I'll probably make a habit of changing it every year. Next time I'll hit NAPA up for some of that Valvoline Dexron VI fully synthetic, ofcourse I find out they have it after I settled on the Castrol.

 

I run Mobil1 all the way around. Engine oil, diffs, tcase, even got Mobil1 ATF if my power steering

Just personal pref I guess, I have a friend that works at autozone so I get all that stuff pretty cheap.
