Torque converter or valve body?

[black coal]

i got a late 99 powerstroke with gauges, TS chip, kn air filter, and 4 in. turbo back exhaust. in the future i will be adding stage 1 or stage 2 injectors. I was wondering what would be the best upgrade to the transmission without replacing it would be? i've heard some guys say to get a different TC while others say get a different valve body. what are the advantages and disadantages to both?

IMO if you spend 800-1200 on a TC and the old trans takes a dump next week..you will kick your self right in the azz cause you will need to spend it again...do the VB from BTS or JW for better stonger shifts and have the chip reprogramed...do the TC when you need to rebuild the trans,,,

How many miles are on the truck?

If you still have a solid tranny then a VB would be ok. Even better with a PI Stallion and VB but that depends on your budget.

But like mentioned above. If you can wait till your tranny takes a big dump and have it built right. It's just a matter of time before the stock clutches and TC give out on a tuned truck. The 4R100's are weak.

The 4r100 is a good trans if modded correctly. ive seen heavy numbers and trans' work fine if only the TC and Valve body are done, if the clutches are in good shapeand not worn to rat **** then replace the TC and valve body..but by the time you do that and flush it out im sure your over the 2G mark..suncoast makes trannys for like 2600 i believe.. i have a built NADP and zero issues..runs at 125degrees continuous and takes a severe beating.. i paid around 3G

the truck only has 112,000 and it didn't do any heavy towing so i'm guessing the trans is in good shape. also couldn't you reuse a suncoast tc cause it has a lifetime warranty?

yes..downside..lets say you had catastrophic failure and you have crap in that fluid..your TC holds alot of fluid and by no means will you ever drain it all out.. so if you blow your trans and the fluid has stuff in it..its in the TC you put that TC in your new trans and it flushes all that fluid thru the new trans and clogs up the new valve body etc..i personally wouldnt do it..but you can..

just cause it never towed doesnt mean its good, ive seen new 4r100s fail after 5K..abuse is abuse right..towing or not....

Towing does not equal abuse, driving style, drag racing are much more abusive than heavy loads. I still have 100% stock trans with 222k miles. But I do not expect it to last forever.
