auto trans info
 

in a 86 gt what type of auto trans were there, and if more than one how can i find out what type i have in the car? and will this tranny be able to hold the torque of a 393/396 motor with nos


thanks

Right now you should have an AOD. I'd defintitely recommend a C4 for your combo though.

On my floor shifter they is no overdrive indicator all i have is p,r,n,d,2,1 so how who i tell if it is aod or something else and number on it i could read without taking tranny out.

thanks

the quickest way to tell its an aod, is the bellhousing. on the bottom of the bellhousing there should be a area with a bunch of squares(you'll know when you see it. Also, do you have tv-linkage or vacuum lines connecting to your trans.?

i dont think i have the tv linkage or vacuum lines to the tranny, you see when i bought it the car was redone on efi no computer etc, so im wondering what kind of tranny it is! but ill check it tomorrow! ill let you know

thanks man!! :D

aod - tv linkage controlled - two cables from throttle lever to the trans near the shifter cable.

c4 - vacuum controlled - vacuum line going from intake to vacuum modulator on the side of the trans.

i have a tv linkage but no squares on the bellhousing, the tv linkage goes to the shift mechanism on the tranny, i dont know if this will help but the drain plug is in the back corner of the pan, and the neutral switch is on drivers side of the tranny on top, if this doesnt help is there any #'s on it that can be found without taking it out?

THANKS

Well the stock aod's, as well as most trannys, dont have a drain plug. You have to drop the pan to drain the fluid so yours must be aftermarket unless a plug was added. If that was the case the pan should say Metric AOD(i think). If I remember correctly, yes the neutral switch is on the driver side. I'm going out right now to work on my tranny actually so if I think of any distinguishing marks I'll post back in a bit.

the casting # should be right above the shift linkage on the case, drivers side.

ie looks like the plug was added but the pan says metric and thats all it says on it im going to look for the code now that i know where to look
thanks

How does that work? EFI is Electronic Fuel Injection, I am pretty sure it has to have a computer.:confused:

I MADE A TYPO sorry no computer, no efi carb'ed

That has to be an AOD then, but check the casting # anyways.

what is your desired purpose for the car with the 393/396 combo u r thinking of? Daily driver, cruiser, pure strip?

my main propose of this cars is daily driver/ street duty and lots of it. i would like to have a stick but if the motor is going to kill it then ill keep it auto. Hey i might even bring it to one of the events when its done to see what it can do (E/T)

THANKS GUYS
