The B&M is OK, but all it does is jack up the line pressure, which is not addressing the real issue. It certainly helps (to an extent), but it is not the way to fix the design PROBLEMs with the E4OD - it's a band aid. Just cranking up is hard on parts and actually hurts the transmission in...

Well, you can actually test the solenoid at the through case connector rather than pulling the pan. You'll need a manual to tell you what pins are for the EPC solenoid. Yes, there are other solenoids as the E4OD are completely electronic so solenoids control trans function. I'm not 100% sure...

Yes, frictional properties are also important expect the 5R110 doesn't have any REAL need for FM different from MercV. The reason why the 5R110 was spec'd for SP is because everything during that era (except for CVTs) went to SP for fuel economy reasons. The same oil is in cars, vans, etc. As I...

I'll also add that on our fleet trucks at work I run Mercon V in the 5R110's. The last 1k gallons or so have been 0204 All Trans, no problems yet, the 5R110's should have about 120k miles on All Trans now I think. I personally feel that the additional viscosity makes a real difference in these...

It's generally a group III base oil, but several types of base oil can be used for SP. There are several brands that meet the SP/LV spec. Valvoline, Napa (which is usually Valvoline), Castrol and several more have SP compatible fluids.

If you could stretch out the OCI to 9k with UOA's then you would only have to change the oil every 3 months. In that service I don't see it as being a problem, but for the first year I'd do quite a few UOA's and see what the truck will like. The 07+ engines are harder on oil from both a heat and...

With unloaded driving you maybe over changing is a bit, but I would not change your OCI. 15k on the fluid in the pan is about right, and you are working that trans harder with the big tires. With what you are doing there is always fresh makeup oil and that replaces the add-pac and ensures that...

If it's towing on the highway I'd probably start with around 5k and sample, then continue sampling every 2500 or so. How fast will the miles be put on? If you are towing on the highway and hot shotting or similar where the truck is on the road for 11 hours a day then 7500-10k would be fine...

It's every bit as good as RTS IMO. Better in some applications. I tend to use Delo in any engine/situation that tend to foam oil like HEUI engines. Aside from that I think it's pretty comparable to RTS, although I just tend to like Delo as I've had the least amount of issue with it over the...

It shouldn't be too hard if you have a wiring schematic. You could islote the circuit simply by unplugging the entire harness from the ECM. Find the pins you need and power the circuit right from the harness termination. But you are probably right, to start off with it's probably be easier to...

A/C's affect on engine cooling is largely dependent on engine size. A 150hp gas 4cyl car will have a different response than a 350hp Diesel in a pickup. With vehicles that have viscus fan drives, the air temp across the fan clutch is the only thing that makes it turn on. For those with electric...

It's been around a while but until recently it wasn't widely distributed. It is a, last I saw, a grp III. It's similar to RTS, but I have found Delo has a much better add-pac with much more anti-foam propeties which are very helpful in HEUI engines like your PowerStroke. Due to the nature of...

I believe the circuit he is testing is a PMW circuit, so making an accurate Vdrop test under normal operating conditions is going to be very hard. In order to do a Vdrop test on that circuit and have a meaningful result you would have to isolate the circuit at the ECM and then provide your own...

You may have to pull the pan and check the solenoid's coil resistance. It's possible the solenoid failed, it does happen. If that is the case they are easy to change. And while you have the pan off I would install a real shift kit and install a large Line mod valve from Sonnax. Cost about 75...

Yep, you have the high torque ZF. Pretty much any Mercon V will work fine in that transmission. I would use RedLine's High Temp ATF for it's slight increase in viscosity and ability to withstand quite a bit of heat. If you don't tow or tow light any ATF will do, remember to change it "often" as...

Not on Ford. In fact Ford was required to retrofit many of the Pre-96 diesel powered trucks to OBDII compatability. I had to take about 30 of our 95 7.3 PowerStroke chassis back for the upgrade. All gas powered 96+ Ford Chassis that I have ever seen come through the shop are all OBDII. At any...

Regardless of what size Cummins you have, if it's an active catalyst engine it requires the low ash oil. However Cummins did come out with a TSB stating it was ok to run CI-4 but the DPF cleaning mileage was reduced. It would be helpful to know what engine you are referring to and if you...
