I have been looking for a replacement auto transmission for an 88 and have located an auto tranny but it is out of a tubo model from Japan. Apparently the turbo II was available with an auto tranny in Japan.

Question is: will this transmission swap into my N/A car without any mods.? Is it a straight bolt in swap? I need a definate answer on this if at all possible without any maybe's or probablies. I am totally unfamiliar with the turbo auto tranny since that was not available on U.S. models.

thanks!

 

hmm. didnt know they came in aut's are you sure it isnt from a FD? and it should bolt right up no problem. just make sure its from a 13b straight out of a fc

 

think about this logically....
will a TII 5spd tranny bolt right up to your n/a motor with an n/a fly wheel?
NO

therefore an auto out of a TII won't bolt up to your n/a motor with n/a flywheel

perhaps if you swap flywheels it would - then you are dealing with balance issues....

short answer - if you need an auto tranny for an n/a BUY AN AUTO TRANNY FOR AN N/A

if you don't want problems during install - don't go looking for them when you're buying parts

 

Remember, ALL FCs in Japan were turbo. So since some of them came with automatic transmissions as an option, one would conclude that you can infact get an auto tranny off a Turbo FC.

I have one sitting here at the shop, came off a Jspec motor, looks pretty similar to the USDM one, but I don't have a lot of experience with auto FCs so I can't claim to be an expert.

 

Uhh, classicauto I did not say anything about a 5 speed transmission. I was asking if the AUTOMATIC transmission from a Japanese turbo will work on a N/A engine without modifications. I know that there are several modifications required to convert to a 5 speed turbo or not.


So, if all FCs in Japan were turbo models then any auto tranny imported from Japan if from a turbo car. Is that correct? If so, then all the salvage companies selling imported auto trannies are selling trannies taken from turbo cars and therefore should work on a U.S. made n/a FC.

Am I understanding this correctly?

Thanks again!

 

Autos don't have flywheels. I think it's called a drive plate. I don't think there would be a problem with balance if you used the same counterweight. So i'm thinking as long as you use the torque converter and drive plate from the turbo tranny it should swap fine just as the turbo and n/a trannys swap. As long as they use the same drive shaft.

I think canadian models also had a turbo automatic, maybe a canadian FSM could help us out some if anyone had one? Do we have any canadian members?

 

Do a 5 speed swap you *****! LoL J/K

I think you need to reread what classicauto said though. If a TII 5spd will not bolt up without modification than the TII auto probably won't either. Thats what he was trying to say I think.

 

re read my post

the point is that the TII tranny has a different input shaft than the N/A tranny.....if you are putting a TII tranny on an N/A motor with N/A fly wheel - it won't fit

the auto tranny from a turbo car will have be designed to fit the turbo sized spline....therefore will not fit the n/a spline

simple


edit: thanks Juiceh

 

If you use the turbo tranny's drive plate and torque converter why would it matter as long as the turbo drive plate still bolts to the NA counter weight?

 

why get an auto? you'd be killing the car's abilities. the overall feel of the car is gone with an auto.

but hey, its your 7, do what you wish

 

flywheel and counter weight are one piece

if you CAN bolt the drive plate from an automatic turbo onto your n/a motor (beats me - I don't know of anyone who wanted to use a auto tranny on their already torqueless n/a) then you could use the auto tranny....provided that the driveshafts are the same length....

see this all comes back to - IF YOU NEED AN N/A AUTO - BUY AN N/A AUTO - don't try and adapt something in and then be in a pissy mood because you were told it would work....if you need gas for your car you buy gas right? not pour 10 gallons of methyl-hydrate in the car becuase "one of your buddies" told you it would work

 

i bet you'd get some performance until the motor blows

 

The whole point of this question is this. This is not my car. I am fixing one for someone else who like most of us has very limited funds. He really cannot afford to do a 5 speed swap right now or we would. There are lots of import transmissions from Japan available with low miles for less money than I could get him one from a salvage yard with HIGH milage. So, if the turbo auto tranny from Japan would work then he could afford to fix his car. If it won't work then he needs to consider other options. The transmission I was looking at only has 50,000 miles on it and would cost $350 shipped to me. If anyone has a good auto tranny for sale and can match or beat this price then let me know.

Again many thanks for all the input. Still looking for that person though that has actually done or attempted to do this swap.

 

You should check the classified section for a used tranny

sorry about your boy - although he should know better.....if he only has minimal expendable income then he should have bought a civic...sorry but its the harsh truth


edit: if he doesn't have much money to spend...why is he looking for some rare turbo automatic tranny? buy any freakin n/a auto he can get his hands on...geez

 

Not looking for a turbo tranny, it just happens to be the cheapest one we have found so far.

 

K, shutup and stop being a condescending **** if you don't know what you're talking about.

Automatic cars come with a FLEXPLATE. There is no flywheel.
The torque convertor bolts to to the flexplate.
The flexplate does not have an internal balance. The counterweight is external, and the flexplate bolts to it.
Where do you think all the aftermarket flywheels get their counterwights from? Its the stock part for an automatic.

I don't know if the stock TII auto will fit exactly for you, or if their controls are the same.
I can tell you that the TII flywheel is the same diameter and tooth pitch as the automatic counterweight.
Based on what mild information I do know... here is what I can guess:
The tranny will physically bolt in without problems and work just fine for you.
