I need a rebuild, what upgrades should I get

[big red 211]

I have an 01 F350 crew cab, 7.3, 4x4, dually, flat bed and a heavy front bumper too.

I just got on the highway today and the tranny just let go when I hit about 60mph. I bought the truck knowing that is was going to need a rebuild, I just didn't think it would happen this fast.

I definately plan on doing some towing with it. That's actually the only reason I bought it. Eventually I might be doing some heavy loads with the truck. It's mostly stock, I just got 6 steel 11R-22.5's in and haven't even put them on yet. I know I'll do get some type of piggy back system for the computer, I just haven't had the truck long enough to check on them.

So, after I saw rebuild kits for around $300 for it I decided I had to mod the tranny too. What would be some helpful internal mods for the 4r100? And for my truck since I'm sure it's a decent amount heavier than most trucks out there and I'm going to be towing with it? What about the torque converter? I know I'll get another cooler for it and set up a temp gauge too.

The BEST 4r100s out there are ones made by either BTS or John Wood. BTS is probably the best but the JW ones are right up there too.

I ment that I'm going to be rebuilding it my self. I just haven't done a 4r100 before so I didn't know what the weak points were. I'm sure someone will have a decent valve body I'll want to use but I didn't know about anything else.

Ok gotcha. Not a clue then

Just order a triple disc billet converter, and suncoast clutch kit, valve body, and you should be good and strong.

Do you have a trans pump puller, a 4th clutch compressor, the center support spring compressor, the od gear set installer tool??? How about piston seal installer tools.??? This trans is not as easy to build as a c6.
There is a reason people charge $2,000 to $3,500 for these trannies.

sorry, I've got to call B.S. on this... the reason people charge so much is they are CROOKS plain and simple. I made all of my "special tools" very easy. it is not hard at all. It may be harder than a C6, but entirely possible to do yourself. These "specialty" shops that do the upgraded parts, put an extra couple of hundred bucks in your transmission then it goes from 2k to 5k... One man can do what another can do, simple philosophy preached by anthony hopkins

If you get into one you'll agree, unless you're "rich" do it yourself. Of course if I had the money I'd have a whole shop full of hired grease monkeys to do all my work for me, but that's not the case...

I've got about $600 bucks in mine so far, it's not hard at all, in fact it was way harder removing the transmission than the rebuild part!!!

Just my opinion though, worth no more than anyone else's.

I wouldn't say they are all crooks. Some have several years experience and ASE certs (like me) and don't just buy the first kit they see and do an install. There is way more than throwing in some parts and calling it good. Maybe you did a good job and maybe your trans won't last very long! I have no prob with guys DIY but don't knock the guys who do it every day and know way more than you do about automatics!

all the tranny shops ive dealt with were crooks, two trucks had to have the tranny rebuilt after 10k on the first rebuild, one truck had a leak 2 days after it was rebuilt.

and many tranny shops just order the reman and throw it in. not actually fix or rebuild it.


to the OP ive heard good things about the Monster rebuild kits for other trannies not sure about the 4r100. but definately upgrade the clutches, valve body, and TC

Not living past 10K sucks and would piss me off too no doubt! The factory clutches work just fine you just need more of them and you need to know what parts need to be changed and what needs to be machined so on and so forth. If you think BTS and Wood doenst have failures, you would be wrong. They do stand behind their work however.
