4r100 upgrades
 

Asked before but haven't got a real straight answer.. I have 2002 F350 Srw crew cab longbed.. Tranny has started to slip and over heats.. Also when I take off sometimes it kinda feels like its skipping.. First auto diesel I've had but wanting to rebuild/upgrade it.. Was wondering if anyone could give me a parts list lol of what all I should build up.. I know TC and valve body prob.. But brands? Want something that is working for everyone else.. I know I'm gonna do bigger cooler to, just haven't decided on which one.. Also a tranny temp gauge ( done been hollered at for thinking stock gauge was good enough lol).. Just need advice, all is welcome.. Looking to order stuff now.. Wallet open lol..

What I do with truck isn't much.. Daily driver, slash tow rig for hauling others stuff.. Kinda hilly around here.. Would love to pull a hill and not have to watch gauge go thru roof and slow down or stop to cool off..

THANKS

call BTS, problem solved forever

Mmmmk.. Not what I was looking for but expected.. Thanks, it's noted!

if i had an auto i would not screw with it myself or have someone try to build it for me. i would buy it from either BTS, john woods maybe twisted or NADP. not worth it to me to chance buying a tranny more then once.

The suncoast rebuild kit looks pretty complete and has most everything you'd need to rebuild it to withstand some good power. I'd toss a Transgo Tugger kit on it, and a Triple Disc converter, 6.0 tranny cooler and you should handle plenty of power.

There is a guy on ebay I've spoken with who sells a "Stage 2" tranny for around $2500 with a 3 year/100k warranty. When I asked him for specifics he came right out and told me all he did, which was exactly the things most do to upgrade these trannies.

Other option is a Ford HD4R100, some vendors can get these for just over $2,000 and you get a warranty through ford for I think 5/100k.

There are plenty of other options besides BTS/John Woods that will withstand some power.

Which suncoast kit u referring to? Ya I've heard good things on tugger kit.. So prob gonna do it.. I found a billet triple disc TC already.. Been looking at monster in box rebuild kits.. Heard any news on them? They offer a additional superduty package to the rebuild kit to beef it up more too.. Thanks

I looked at Monster and their tranny's/kit's didn't really impress me much at all. Sounded very stock rebuild'ish to me.

Here is the suncoast kit I was talking about:
