Ok i have just a simple question for the tranny pro's on here.
I gave my son my old 84 F150 300(4.9) 6 cyl AOD auto when the tranny finaly went out after over 300k on the odometer.I had recently done the whole top end and new gaskets and oil pump on it so the engine is really in great shape.
I have an 85 GT mustang 5.0 AOD ragtop that a deer totaled out ,the drivetrain is still in excellent condition and told him to just take that tranny out and put in the truck.
My question is,is the torque converters different as in the stall?..if so..would it really matter using the mustang converter in the truck since i wouldnt use the one in the truck in fear of it being messed up and also having metal shavings from the bad tranny.
I know the gearing will most likely be a little different in the 2 but he will only be using it mostly for hauling light stuff or just goin to jobsites for work.

The 4.9 converter is going to be a lower stall converter than the 5.0, by a few hundred rpm's.

Could you still use the 5.0 converter? I'll bet this has been done by mistake many times in transmission shops.

I say yes you could do it, and again, some difference in stall speed but, not enough to make a real difference, in my opinion.

Yes..were planning on using the 5.0 converter with the 5.0 AOD into the truck,if thats the case,the old truck has highway gears in it and if anything the higher stall in 5.0 would make it haul a little better out of the hole.Thanks..John

Hi,
I'm not positive about this but I think the early
AOD's {they made changes in 91} are all the same, with
the gearing similar to the FMX one of the transmissions
that it replaced.
Good luck,
