Stick with whatever is in there. Unless you're doing a full flush. Typically it was Mercon SP in there, but Ford just updated it to use Mercon LV now. If you haven't had a flush in a while, it's probably still SP in there. I'm not sure if you can still get it at Ford or not, but I'd imagine so. It is superceded by the LV now. Also don't get the part direct from GoGo, I think DPP or someone else sells them as a distributor, get it through them. I know the link has been posted here recently, try going through some of the threads the last few weeks or searching for it.

 

what does this gogo direct solenoid do???? When you first use a programmer or box like the Edge the trans has to learn all over again, you are supposed to do it in steps, drive in each setting for a while/couple of days/ so the trans learns the power. I never have a problem switching between settings, onlt time have to be carefull is after the batts. have been disconnected because it will totally confuse the trans if I jump on it, it doesn't know what the hell to do and will be all over the place. The SCT controlling the trans might not have to learn like the edge does.

 

They all have to learn, the only thing is the trans can only learn so much. Tuning sounds better than trying to learn to me. The trans isn't going to compensate for an extra 100hp on it's own.

Compare a 5R110 to an Allison. Everyone raves about the 5R, and rightfully so, but these are guys who are actually tuning their transmissions. Look at the 6.4 crowd... holding almost 600rwhp on a stock trans with GOOD tuning. Look at the Allison now, everyone who knows nothing about aftermarket diesel performance thinks the allison is all that. It is a great trans, it just can't take any custom tuning, so it can't hold much more power over stock really, if you plan on beating on it. A 100hp tune will destroy an allison pretty easily if you're not careful. Tuning is absolutely essential to long life in a 5R110.

Even with my SCT, I like to do a little bit of driving before I really beat on it after a tune change. They always need to learn after a flash, it's how it acts after that learn that I'm talking about. The Edge simply doesn't tune the transmission, no if's, and's, or but's about it.

To answer your question, (bare with me, I'm not a trans tech so I'll try to explain this as best as I can) our transmissions are shifted by electronics and a hydraulic actuator is what applies the fluid force to keep the clutches together. These solenoids are what do this function. There are 6 of them in the trans. Each one applying a hydraulic force, driven by an electronics module. They can sometime stick and get lazy, and they can only flow so much fluid. The direct solenoid from GoGo controls the direct clutches, 3-5 shift and reverse. It simply flows more fluid, faster. I think they claim something like 4x the fluid in 1/2 the time...

Here it is, if you get it order directly from these guys. The info is right there about it too: GoGo Diesel DirectSOL Modified Direct Clutch Solenoid Ford Powerstroke 6.0L / 6.4L

 

I didn't mention this earlier, but here's my Edge experience: 1-2 fine, 2-3 fine, 3-5 (yes it skip shifts, but that a whole new thread, possibly even a sticky) well 3-5 was like, imagine driving a car with a 4-speed manual, accellerate to 2000 rpm, holding rpm, ease in the clutch, still holding rpm, lazy shift to 4th, then DUMP the clutch. Holy cow! I thought it was going to rip the rear end out. 6th gear (OD) it would do that twice like it was "hunting" for OD.

I dumped $250 on a new valve body at the advice of a local shop, only to find it did it again as soon as I put the Edge back on. Remove the Edge, still slam shifting, discon BOTH batteries for 22hrs, reconnect. The slam shift was gone, so is the Edge. So your issue may be your Edge, not your direct drive solenoid.

I have an SCT now, it takes about 4 complete 1-6 shifts for it to learn (3-5 flares a little), but after that, it's fine. This is why I WILL NOT use my Edge even as a monitor.

Try thinking about it this way (it helps me), the 5R110 is like an AOD with solenoids in the valve body. Instead of OD only working with 3rd gear making a 4 speed, the OD unit works on 1st, 2nd, AND 3rd gears, now you have a 6 speed, 1st, 1stOD(referred to as 2nd), 2nd (referred to as 3rd), 2ndOD (not usually used but would be 4th), 3rd (referred to as 4th, but ACTUALLY 5th), 3rdOD (referred to as 5th, but ACTUALLY 6th). However, because 2ndOD and 3rd are so close, it skips 2ndOD unless its extremely cold outside. If you're keeping up, this should explain how it does a 3-5 shift more often than not.

 

Yes the 5R110 shift pattern is 1-2-3-5-6 OR 1-2-3-4-6, it can never go from 4th to 5th, EVER. 4th and 5th gears are VERY close together. It typically will use 4th gear in cold weather, since it can't reliably make a 3-5 shift (see solenoid issues discussed above). Also once in a blue moon if you're cruising in 6th and hammer on it, it will drop to 4th for that tiny little more acceleration, but there are a lot of factors that determine that. 6th is OD. Most people get confused and think they can feel it shifting all gears, but the last one they feel is actually the torque converter lock up. Running a race tune with an early lock up will make that go away, so you'll know it's shifting gears and not the torque converter doing it's thing.

 

Ok so get rid of the edge ( don't even use it as a moniter) so what do you recommend for sct? Bc I like having the moniter? And it hasn't had hg done yet but it will in the future... I can't get a sct live wire with 3 factory setting and it says I can add 3 custom tunes for $589
I'll have to sell my edge so what do you think it's worth?

I can get sorry

 

Tough to say, I've never had to sell one. Why can't you use the Edge for gauges and just get an SCT handheld unit? That's not a bad deal on the live wire though, who are you getting it through. Almost as important as the choice to use an SCT, is the choice of which tuner you're going to use. Stick to the "name brand" guys... Eric @ Innovative, Matt @ Gearhead, etc...

 

Well I hear nothing but good things about Eric @ innovative... So I would probilly go with him for tunes... And I found a sct live wire on holderdown performance... SCT X3 w/ 6.0 Custom tunes
It says custom tones by innovative??

 

I wouldn't use an Edge that has power settings as a monitor simply because of the "Transmission Learn" section. Mine was ok without the Edge, then as soon as it went back on the trans went batty again.
I just loaded up Matt's SRL tune, I didn't need to do the back and forth tweaks (maybe I got lucky) and I really like it. I'll be using the 8K tow tune this summer hauling my Hot Rod to and from the track. If you're really lucky, you can get one off of eBay for dirt cheap, then buy the tunes for it, I did, saved mucho dinero.

 

Well I took my truck for a drive last night and the tranny seems to be fine now, I think it was just a relearn thing... So now I'm just waiting on my AE to figure out why I'm only getting 8.8mpg!!! If you have any ideas were to start that would be awesome!!!
