I am wanting to upgrade my stock tranny for towing. My 10k lb rv really puts a load on my tranny especially climbing hills. I know there are allot of choices out there, ATS, BD, Suncoast, Goerend, etc. I am leaning toward Source Automotive which is closest to me. Any thoughts or suggestions?

suncoast hands down ,they are very good to talk too ,they will build a trany for your needs and not try too force you to buy something you do not need ,most cases for towing its just a upgraded valve body and torque converter

I see no reason to do any thing to your tranny. It should do the towing of your trailor jest fine if you have not add over 50 more HP . ==== Good Luck

As far as the big brand names i here good things about goerend.I had what i call a first gen suncoast.It was good.I do here bad things about ats.Never had one just hearsay.
