Everything was as described and arrived on time. I used one of these in a 4l60e before and loved it. This on is for a e4od tranny, and the shifting is guite harsh. And that was with the RV springs and not the street ones. That's the only reason for the 4 stars. I'm sure it's working as it's supposed to, just a little too harsh

Have not been able to find a shop willing to install it and when I spoke to their customer service (in the US) I asked for shops in New England that have experience with it where I could drive to get it installed, I was told they do not yet have such a list.One mechanic that thought he could go for it and when he read the instructions, he was not certain it could be done without dropping the transmission. He called the factory using the number in the instructions and was told he would have to drop the transmission.When I ordered, I did speak with the factory to get guidance as to part to buy for my MH and asked how much time/trouble to install. I was then told that a tech that had done one before could get in done in less than 2 hours, without dropping the transmission... I think the folks answering the phone should get their stories straight.And if one reputable company buys another one, the new owner should know where the products are used and referrals to shops that can install.I am sure that if I do get this installed one day, that it will do what it is intended, but for now, it is still sitting on my workbench.

nice firm shifts now without the overlap.Fairly simple to install . I did also order a repair harness and replaced the electrical male plug on my 92 e4od .

I have always had shift kits in my hot rods turned up as firm as they can go. I needed something for my winter beater, a 94 F150 4WD with the 5.8. The stock transmission was HORRIBLE! I may be spoiled from driving my newer diesel around, but I can't believe how soft and slow the stock 94 transmission shifted. I didn't want anything that would chirp the tires when it shifted as I mostly drive this in the snow and didn't want to lose control every time it shifted. I did the stage 1 - Heavy Duty springs and I skipped the electronic resistor install thing (pending what I thought of the way it shifted). Well it shifted perfectly! It firmed it up a lot, without being neck snapping. Brought it up to par with newer trucks, instead of a 1950's Cadillac feel. Driving around "normal," 1/4 throttle or less, you can tell there's a difference, but you can't feel a thing. Start opening it up a little, and it'll push you back in the seat a little bit when it shifts, but I won't be giving it that much throttle 90% of the time and definitely not in the snow. Combined with the fully synthetic Mobile 1 ATF and a new transmission filter, this was the best $130 I've ever spent. I can tow and haul with a lot more confidence about the transmission.Installation wasn't the greatest. The biggest thing was getting covered with ATF. Nothing like oil dripping down your arms and into your armpits while getting all the parts out of the bottom. If the transmission is out of the car already, that's a huge bonus. But otherwise a very straight forward install. Make sure to get some petroleum jelly for the install to hold all the little check balls and springs into place when you put it back together. Take your time, be careful to follow the instructions exactly and anyone should have zero problems installing. I also believe you can skip the wiring resistor install thing, as that thing supposedly only firms up part throttle shifts, which I didn't really want firmed up much.***Update 3/10/2017 Transmission is still doing great! My father in law uses the pickup around the farm. He tows WAY beyond the rated capacity with no problems pulling full grain carts around the farm or whatever.***Update 7/22/2020 Transmission still going strong with 200k miles. Got the pickup back when my father in law retired farming. The torque converter did start to shudder, so I replaced it when I had the engine overhauled. Still shifting like a absolute rockstar on the original transmission!

The B&M Shift Improver kit is a great product (actually 2 in 1 since it has 2 possible setups), it comes with all the parts necessary to modify the shift speed and firmness (it won't modify the shift points), and to augment the pump pressure output in your trans. This particular kit is aimed at the E4OD transmission found in many Ford trucks from 1989 to 1997, in my case this kit was installed in the E4OD found on my 1993 Bronco. If this is your first time messing with a transmission then this is your kit, detailed step by step intructions will help you all the way, and it isn't as involved as some other kits in the market. Regarding the quality, it's top notch (even though the supplied drill bit broke), the springs are beefy and strong compared to the stock ones you'll find in there, and there is a new cork pan gasket which is very nice (not my favorite kind, but it worked great and it hasn't the slightest hint of a leak).The installation will require some time and attention, but it can be done easily and with mostly regular tools, if the trans is out of the truck I recommend doing the pump spring modification, if not, then you'll have to do the resistor mod (this is a "either one or the other" deal, don't do both). Personally I have refrained from doing the resistor mod, but might do it in the future. Since you have to take the trans pan down I would advice adding a drain plug kit if you don't own one already, these are a couple of examples: . If like me your objective is to improve the life expectancy of your trans, the addition of a cooler will also help you achieve this (heat is the #1 cause of transmission failures), I also went with B&M and installed this one . If you want further help with the installation of both the cooler and the shift kit, enter this search in your fav search engine and you will find a pictorial elaborated by me: "Ford (89 - 97 E4OD) B&M Trans Cooler and Shift Improver Kit install (No resistor)".The results? well, now my transmission has firm, crisp and quite fast shifts for all gears, which reduce the clutch discs wear by reducing unnecessary slippage, which in turn also reduces heat. I went with the Stage 1 which is a little softer, this left me with a firmness you can clearly perceive, but without being uncomfortable, all in all you will like this product very much.
