Be very careful that you put the hose from the funnel into the nipple on the top of the radiator. I got it backwards and spayed nasty burnt transmission fluid all over the place.

I used 1/2" clear vinyl hose. You definitely want to go the next smaller size. 1/2" doesn't seal tight enough on the nipple attached to the radiator inlet side. I was able to make it work with a zip tie but only after leaking a good bit more clean ATF until i figured out how to seal it better.

But, the good news is that the mess and frustration was totally worth it. My 2008 V6 with 195k miles shifts much better now. Better than it ever has IMO. It is much more drivable around town. Besides quicker shifts, one of the things I have really noticed an improvement in is when coasting up to a stop light and then hitting the gas again before coming to a complete stop. Before, there was a slight delay between stepping on the gas and the truck accelerating. Now it just goes. Awesome.

Also, I bought 12 qts of new fluid but only replaced about 11qts. After pumping out about 8qts, I noticed that the fluid coming out was looking much better than it did at first. I decided to stop with 1qt of the new fluid left just in case I had a spill or needed to top it off after all was said and done. In the end, I didn't need i but I'd rather be safe than sorry when it comes to stuff like this.

Anyway, thanks for the post! It inspired me to finally do this maintenance which was seriously needed.
