They were recommended by my mechanic (Saturn-Mike) as his preferred tranny shop. They test drove my Sienna that has 186,000 on it, and get's 20 mpg pulling a 2500# boat & trailer. Per brother Murphy, it refused to slip or chunk on the down-shift. They explained that when convenient, I should leave it over night so they can test it cold and tethered to a code reader. He explained that codes may back up behind other codes. He explained the function of viscosity and seals in well used transmission and how valves might not work as well until the fluid warmed up. They even offered to meet me halfway to pick up the car since I drove 30 miles to get there. While test driving I mentioned that the vehicle probably would not show it's ills, and he said, " I'm over here driving this thing thinking, Mister, you have 186,000 on this thing and I don't notice anything wrong. What exactly do you want?"

These guys were recommended to me by a mechanic friend who does all my other maintenance. He is known as "Saturn Mike." I gotta' 200,000 on a Toyota Sienna. I have the transmission serviced between 30,000 and 50,000 miles depending on fluid color. I tow a 2700# ski-boat about 1500 miles a year. Transmission was gasping for air. I told Mike what I had found... slipping, terrible sounds not fit to print, and I explained I couldn't pull up a 2 degree grade, and that the fluid looked like a latte. I had changed the fluid over the weekend and thought I could drive it to his place. He said, "NO, It sounds like you cooked it." "Take it to these guys. I don't have a lift nor the time for what is about to happen to you, and besides, I take my transmissions to these guys. You can TRUST them." I called Greenwell and gave them my story. They said, look, new fluid may do more harm than good. Have it towed here, let us look at it and we'll see what we think. They even offered to come with a trailer and pick it up. I asked them about a junkyard tranny, given the miles. They said they'd do anything I requested, but they recommended a transmission with less than 100K and that it be from somewhere near enough that if there was a problem, I might have some recourse. They then asked that I find a comfortable chair and gave me the pricing on a rebuild and on a new Toyota tranny. I asked about the rebuild and they said, look, labor is the same. If we rebuild it, we know what was wrong, we've fixed it, and we've guaranteed it for a year. It will be essentially brand new. Toyota's, it will be OEM, new, and you will still pay us labor. Junkyard is definitely an option, but it is luck of the draw. I said what bout 200K on the van. Greenwell said, let us put it on the computer and look at the vehicle. If it checks out and is in good shape, we'll tell you. If it's a heap and other things are falling off, we'll go the junkyard road. Having just returned from vacation, they said the van looked great, and it coded well. Turns out a coolant tube cracked, and I was filling my tranny with antifreeze every time the car overheated which explained the mocha colored fluid. When they cracked the case, they found rust. They rebuilt it. They used a lot of new parts, as it was very, very cooked. They ran codes several times to make sure they had covered the transmission. They added a transmission cooler to help preserve the coolant (which Toyota recommends on their trailer pkg.). My vehicle drives as smooth as silk now, shifts well, and should be good for at least another 200K. It wasn't cheap, but it was fair, and a lot less than a crappy trade-in price and a new car. It was done in good time, two days, and then they test drove it home, and around their area for half a day to make sure the on-board computer was re-learning it's role. I am VERY pleased with the results and with their instructions.
