    just going over some ideas and thought to start counting up crawl ratios, tell me if i got these right

    th400 2.48:1 X np 205 1.96:1 X gears 4.56 = 22.165

    th400 2.48:1 X np 203 2.01:1 X gears 4.56 = 22.730

    700R4 3.06:1 X np 241 2.72:1 X gears 4.56 = 37.953

    sm465 6.55:1 X np 205 1.96:1 X gears 4.56 = 58.541

    th400 2.48:1 X doubler 4:1 X gears 4.56 = 45.235

    sm465 6.55:1 X doubler 4:1 X gears 4.56 = 119.472

    did i get these right just making sure i understand how to do this and if so why dont more people have the sm465? is it weak? thanks

    The sm465 is not weak - most don't prefer a stick.

    I sure do miss my auto. If I was able to do it over again, I would do the TH400/doubler.

    Good luck.

    <font color="green"> The 465 is super strong, but some people have a hard time driving on trails with a manual. A hand throttle helps alot. /forums/images/graemlins/thumb.gif I love my 465, wouldn't trade it for anything, except maybe an NV4500. </font color>

    Don't forget, that with an auto, the TC actsw as a torque multiplier and almost doubles the torque...therefore, you must multiply the tranny ratio by 2 to get the "effective ratio"...As for the 465, I think that some people don't want to have to think about shifing when running a trail...the 465 is a VERY, VERY strong tranny...it was usend in trucks all the way up to 2-1/2 tons....the inly down side that I have noticed with the 465 is the lack of an OD, and the wide gear spacing... One day I will swap in a nv4500 or nv5600. For a rig that has 35's and sees a lot of freeway use, gears lower than 4.10 really don't cut it. Sure you could put in 4.88's but you'd be revving to high heaven just trying to keep with the flow of traffic...for a rig that only sees city and trail use, a 465 with low gears works fine...I have 35's and a 465 with 3.73 gears...it is a good compromise IMO...When i GO TO 37'S, i MIGHT swap in some 4.56, but it is up in the air...
    Basically, can you live with a stick on the trail...if so, I think the 465/205 is a SWEET setup...
