Auto trans behind a Toyota

[HardCharger81]

I was wondering if anyone was running an automatic in their Toyota pre-runner/7/1450 truck.
If so, is it a Toyota trans? Or have you adapted it to something else? Did you buy an adapter, or did you make one?
Any info on the subject would be great. I'm trying to get the drivetrain together on my Toyota project, but I'm not sure if I want to got auto or manual.

Thanks

Who makes an adapter to bolt a TH400 or TH350 to the Toyota?

I've been looking everyyywhere too... Cant find anything.Checked AA, Called ORS, called some company in Australia that would fab a one-off, but for the cost of it and the cost to ship, it would end up being what it would cost me to do an LS1 swap haha

Wht engine are u trying to adapt it too?I'm kind of looking for the same but i have a 3.4l any idea's or is that th400 adaptable to my engine?

[HardCharger81]

Protruck emailed me back, they do put the 4.7L in front of a TH400. And the plates to do it are $1300

For now I've given up on it, and I'll be using the R151 standard that I have. Maybe this winter I'll try and make my own adapter.

If you're running a stock or mild engine I'd stick with the factory tranny.

I found these on the LC Engineering website. Feedback about the company and their products seems to be pretty mixed, but you could always give them a call.

I searched LC Engineerings site, never did I find that.... Thanks!

[AZYOTA]

hey thanks gearhead for that info

[DRIVE Jon]

Thanks for the link to the LC gm trans adapter. I also have never found that part on their site...looked for these for a long time. Very cool.

Thanks again!

So I take it you need the adapter and the flexplate? Is the flexplate and the flywheel the same thing? I am a engine to trans rookie...I changed out a clutch once but barely remember doing it.

What are the other things one would need to complete a 5VZ manual to GM auto conversion. For instance...is there an adapter for the engine output shaft to fit the GM Tranny input?

adapter*
flexplate*
shifter
trans coolers
trans temp gage
modified/new driveshaft
transmission mount adapter? Or fab my own?
Tranny
torque converter?

My suggestion would be to LC Engineering and ask them specific questions.
BTW Flex plate=flywheel
My best guess would be the new flex plate bolts to the Toyota engine's crankshaft but has the GM bolt pattern for the GM torque converter.

I have a newb question..whats wrong with the manual five speed behind the 5vz?

Nothing at all. The Toyota R150F is a strong transmission. When it comes to having three pedals (manual) or two (automatic), its all personal preference. By switching to a GM auto trans, you don't have to worry about any electronics for the transmission. It is just giving the guys that want to run an automatic another option.

It is really just a lazy thing. It would be nice to keep both hands on the wheel...although I'm sure I would get a manual valve-body...so ill still be mess'n with something. I'll probably end up staying with the manual as long as it stays with me.

I did have to replace a bearing in it that was making noise...not the throw-out...that got changed as well. Some other bearing failed. I also hate when you are hitting rough stuff and it pops out of gear...doesn't happen that much.

[HardCharger81]

Yeah, I was just looking to make the truck easier to drive, as well as more reliable. Toyota automatics aren't known for being real stout, and there's very little aftermarket for them. A GM trans, you can pretty much build or have built any way you want.

I too will probably stick with the manual that I have for now. My understanding is the R151 is pretty tough.

as stated the R150(1) is a strong trans but like all manuals they don't like deep whoops, larger tires, and superchargers. Bonzen with his S/C 3.4 has gone through 2-3 trans in his truck do to the loading/unloading breaking gears. A auto can take the shock alot better since there is a fluid coupling to the motor.

Anyone on here have any desert experience with IPT?

If I ever get it going I'll let you know how the th400 and 3.4 combo works. As far as converter goes Hughes built me one, so we'll see.
