JMHO: Look into can Call Brian-->BTS
www.brianstruckstop.com His shop is in Lead Hill, AR. Brian builds a very much so bullet proof transmission. If you can't drive too his shop, and have his crew install it for you... U can have brian ship his transmission to your local shop to have it installed. I myself am going to take the time to drive there, and have brians shop install it. That way I know it done right, with no short cuts.
Good Luck.
