What kind of tranny?

[tnh2oman]

I've got an 89 F150 302 auto. The door sticker gives a T code for tranny. When I look up the code on some websites it says a T is a four speed auto (ranger). My indicator has P R N OD D 1. There is no overdrive lockout switch since it is obviously done by shifting into D. Anyone know for sure what transmission this is?

I believe that was the A4OD. The trucks of that era had little chrome tags on the tailgate that said 'overdrive'.

C6 would be PRND21
AOD would be PRN"OD"D1
E4OD would have the lockout button.

There's no tag on the tailgate and the indicator has P R N "OD" D l. There is no switch I looked at a 90 yesterday and it had the switch but mine has nothing in that location.

AOD On newer trucks 2wd if you have a lock out button it's an AODE

Oops, I was mistaken. Adrianspeeder is correct.

I have never seen the aod/e transmission in a truck. A 4r70w has a larger output shaft bushing and a different internal gear ratio. Physically they look the same, but if you go getting parts for an aod/e they probably won't work and if they do they are not as good as the 4r70w counterparts.

one example is my friends '97 nascar p/u.I didn't believe it till I went under it and saw for my self.He has o/d button on shifter I thought it was the same trans as in my expedition,he had a race shop install a shift kit for X amount of $(cheap)I wanted the same time the guy told me it was going to be alot more different trans, thats when I got under his truck and looked.It also said it right on the trans pan

I failed to mention that it is a 4WD truck. Sounds like it must be an AOD since there's no OD lockout button or switch.

That is what it is.
