clueless about AOD trans
just realized the 87 150 I just bought has the PRNDD1, which I'm gathering is a overdrive tranny,the doorjam tag says T for the trans code,never had one so I'm clueless about them, wheres 2nd gear? should I drive around in overdrive or use the first D? I can't really feel it shift 4 times when in overdrive, if theres no second gear setting how do you use the trans to slow you down on a steep grade?. whats the pro's or con's of theses transmissions, thanks in advance

It will only shift three times.
Starts off in 1st.
Shifts to 2nd.
Shifts to 3rd.
Shifts to 4th, or OD.
If you want second gear on the road just pull it into L.
It will downshift to 2nd. and when the speed gets low enough, into Low.

yeh I see it doesn't have a trans cooler I'll install one, I read you should change trans fluid quite often on theses AOD's do you know anything about that, and something about ford has a TV cable boot replacement kit that should be installed, and it is real critical that the TV cable is adjusted properly??? I just don't want the tranny to fail cause of something I neglected. thanks for your input

yup change the fluid and filter. the convertor has a drain plug too.
If the TV pressure is off in these transmissions they won't last very long.
The critical area is on top of the engine. Where the linkages connect.
