Automatic trans swaps?

Would swapping in the U250E five speed automatic into my 92 V6 be possible? And if so, what would be required?

Cool

Anything is possible. Why would anyone put an i4 gearbox on a v6.
If Toyota thought they could handle the torque output, there wouldn't be a seperate family of transmissions.

Gathered this from wiki:

U250E

The U250E is an updated U241E and now has 5-speeds.
Applications:
  • 2005-2007 Camry (4 cyl.)
  • 2006-2007 Solara (4 cyl.)
Not sure if it would work on the 92 V6 or not, since it only lists it being used on a 4cyl.

Well, it was a toss up between that and the U660E, since those two have the nicest ratios imo, but I figure it'll be way harder to find the V6 tranny compared to the I4 tranny, and was wondering if the U250E would bolt up to the 3VZ... Torque output shouldn't be very different considering the difference in age and engine families. The 3VZ makes ~190ft/lbs, and the 2AZ makes ~160ft/lbs, which is only a 15% difference. It's not like that 2AZ at 160ft/lbs compared to the ~250ft/lbs of the 2GR. So... would they bolt up? Would I need mounts, etc.. Or is it impossible w/o fabrication?

why would u go through the hassle of swappin in a tranny only to go with an auto. ud have to first find a tranny then fab it to fit. u can get the E153 and have 5 MANUAL gears. but yes, with enough money u can swap anything.

Mileage. The E153 is strung so f'n high, I'd be lucky to pull 30mpg highway. Unless I could get a custom 5th gear made that was low enough, and fit in the trans case, it'd be pointless to go with a manual for what I want. The newer automatics have more gears and really nice OD ratios, so I should be able to average at least 40mpg given how I drive. If any of those taller automatics are bolt-ins, it's probably possible to provide inputs to the trans computer in order to make it work. So... It depends. How much would an E153+custom ~.55 fifth gear be? And how much would rigging one of the newer automatics be? Given free access to a small machine shop and whatnot.

LMAO, so ur justifying spending over a thousand easly on a tranny swap for better gas milage . though i dont doubt that ur right about savin gas, the car will be dead long before u make up the money spent on the swap in gas. honestly, if u want better gas milage then get a different car like a corolla or civic. but i would say that the e153 would be cheaper since the parts can be gotten off of cars from 92 all the way to 01. a new tranny swap would be more because of the custom fabrication and trial and error for being the first.

Cool

What he said. I don't care if someone gave you all the parts to convert to any newer A/T regardless of what transmission you currently have.
It's not worth the effort. Especially considering the problems with the 5 & 6 speed transmissions.

Well then, will a ~.55 fifth gear physically fit in an E153 trans case? What problems are you talking about?

Also, you DO realize those 5-speed Auto's are Drive By Wire I hope. You better know a LOT about eletrical wiring.

Lemme see, at ~40mpg compared to ~30mpg with gas at $3 a gallon (if gas goes higher, adjust the number proportionally), it'll take me ~40,000 miles to save $1000. I think the car's gonna last 40,000 more miles, considering it's gone ~170,000 so far. I'd rather have a full size V6 Camry that got the same mileage as a smaller compact. More room, better acceleration, etc... With the same mileage. Whats not to love? Maybe your Camry will be dead in 40,000 miles, but I doubt mine will be.

Anyway, the point of using the automatic would be if it bolted up. If there was definitely enough room in the E153 for a ~.55 fifth gear, and it was machinable via a small shop, then I'd probably go that route. Either way, no one here has answered any of my questions. Will the U250E or U660E physically bolt up to the 3VZ? Is there enough room in the E153 tans case for a ~.55 fifth gear?

Yup. I was EE until I got so bored I had to transfer or risk sticking my head through my desk.

I do not think anyone has ever tried to see if they fit, haha.

hey man, if u really wanna do it i say go for it, but its not even so much the money for the tranny its the time ull spend getting it done, then having to fix somthign u encounter. i would predict that all said and done ull spend well over 3 grand to do it, or hundreds of hours. but if u do then kudos to u, but i wouldnt expect a whole lot of people being able to give u advice other then "dont do it" because ur the first and prolly the last that will consider it.

^ To be honest, I thought of doing it as well. Just was not feasable for me personally. Since the 3VZ/1MZ have interchangeable trannys, I'd think the NEWER 1MZ's with a 5-speed would be backward compatible with fitment.

Dont quote me on this, but wasnt the first 5-spd auto with the 3.3L Camry, not the 3.0L 1MZ-FE?
