Hey Doc, I think I'm sick. I just paid $38.00 to fill my R/T up with 93. It went 240 miles on the last tank (12mpg). My friend's fuel cost for his Cessina is comparible to my R/T! I should have bought an airplane.

Well, My 2000 R/T is getting about the same gas mileage as yours. I got a check engine light associated with the problem that came up with code P1740 --- Torque clutch converter / overdrive solenoid. I took it to Dodge and they said it needs a new transmission. It seems to be shifting fine, but it is sucking down the gas like yours. They quoted $3,600 for the job. Yikes. I bought the thing used, now I am getting hammered. Hopefully your problem is not as dire as mine.

Well, I said earlier on another gas mileage thread that I thought it was the transmission. The trans shifts way too smooth (amost slipping?). I think I will install a shift kit just for sh!ts and giggles. I have a 3 year extended warranty good through 2006. So, I'm not too worried about it.

The solenoid is replaceable. If your torque convertor isn't locking up then you should be getting much worse gas mileage than me. My torque convertor locks up, but it feels weird when it does.

I got spoiled driving the 4.7L w/45re. It shifted perfect and was always in the right gear. The 46re SUCKS! Beyond any doubt, this is the worst transmission I've ever seen. There absolutely nothing it does right. I can't see how a major corporation like DC could allow a POS like this out the doors. There's no way in hell this trans should be allowed on any vehicle. If I keep this truck, I will figure out a way to put the Viper 6spd in it. I'm concerend about all the horror stories about swaping PCMs. I'm hoping I can get one out of a 5spd 5.9L Ram and use it with the 6spd. I may get tired of screwing with this thing and get something else.

The other thing I notice with mine is when I really stomp on it starting from a stop or low speed I have to get off the gas or it looks like the transmission will let the engine blow well beyond the red line. I'm not about to test it to see how long it will let the tach stay pinned to the mechanical stop. I thought your comment about the smooth shifting was interesting. Mine is real smooth too, which is why it seems so hard to believe anything is wrong with it in the first place. I have been disconnecting the battery each time the check engine light comes on with the P1740 code. It usually stays off for a few hundred miles before coming back on again.

WipLash,

Should be interesting to see you park at the 7-11 in your Cessina-bird.

By the way, with whom do you file your flight plan for your R/T?,..D

I usually make my reservations ahead of time at the county jail.

Tommy,
How many miles does your 4.7L have? I got consistent 19mpg city/highway with my 4.7L up until it hit 16,000. It fell to 14mpg city/highway after that.

I need to do my mileage. I have a '95 CC 4x4 with 3:55's in it. It does DAMN good on the highway, but around here (state capitol), I can throw $20 in every three or four days. And that's not giving me a full tank of 87. To fill up it's closer to $30, sometimes more! However, on my last full fill-up, I drove home to visit my family in the country, and all that highway driving (both on the way down, while there, and on the way back) got me 460.2mi on the tank. I rode the gas-light in and it was dang-near dry when I filled again. I had to put in 21.something gallons, so it was sucking fumes. Still, 460 miles on a tank is good.

Sephiroth,
That's what my 94 5.2l would do. I drove a paper rout with that truck and still averaged 15. It was 2wd though. On the interstate cruising at 80mph it would hit 19mpg as long as I never punched it. At 70 and 75mph it would hit 21mpg. I never drove it on the highway at 55mph for a full tank of gas to see what it would do. My 4.7L only would hit 20mpg if you drove it 55mph and never got the rpms over 2K.

I think the best I ever got out of my 92 4x4 was 16mpg. I drove the hell out of that truck 24/7!

Adam,
There has been a shop advertising viper tranny kits for the Dakota. I don't remember the shop's/guy's name. The last I heard he was supposed to be through with all the R&D by now. He posted a thread/reply on this forum. It was recently brought up again. I'm going to look into it seriously. I will probably wait until my warranty expires to do it. Then again, I may not....
