Hey guys,

I have a 95 f150, 4x4, 300 I6, and a manual trans. I am wanting to switch to an automatic. Will an Auto tranny bolt up to the 4.9L? Would there be any problems with the computer?

Last but not least, but does anyone have suggestions on which tranny to get?

Thanks again....

 

The E4OD is the tranny which Ford used but you'd need a new computer and wiring harness. If you want an OD tranny you could put in a mechanically operated AOD (do not use an electronically controlled AOD-E/4R70W, there is no computer to run them with the 4.9.) If you can get by without the OD then you could use a C6.

The 4.9 shares a bellhousing pattern with the SBF so any tranny which fits a 302 or 351 will fit but the V-8 flex plate will not work. The 4.9 requires a zero-imbalance flexplate.

 

check out planet tans, i head they are pretty cheap and the results look great

 

The M5OD 300 combo is a rarer popular one. I'm sure a handshaker fan would be interested.

C6 if you want simple, but no overdrive.

i also have a 95 f150 4x4 5 spd with the 300 six and i would like to do an auto swap.. so what your saying is that with an aod tranny i could just bolt it up change the steering column and guages so that i have the auto guage and it would work?? obviously get rid of the clutch related stuff too...

 

Before the introduction of the E4OD ford used the AOD behind the 4.9.
Yhat means it can be done. How simple it is to do is another matter. Whether you'll like the results when done is also questionable. The AOD was not Ford's best-ever idea.

 

SR, ya found an example of a 300 AOD?

The AOD came in in 1980, the E4OD was introduced in 1989.
Any overdrive auto in those intevening years is going to be an AOD.

Between the weak input shaft, the flimsy valve body, the narrow OD band and the sensitivity to TV cable adjustment, I don't really like the AOD but cutting cruise RPM by 1/3 has its advantages.

 

Right, but the only example of the AOD in the '85-'88 F-150/'89 Bronco I've found was with the 302. 351w/300's only otherwise with the C6 for the weaknesses you mention.

Really? I could have sworn it was used behind the 300 in at least some of those years. Perhaps in the Econolines? At any rate, it can still be fitted to a 300 with a little work. Since it's not computer controlled there's no control interface issues. The aftermarket offers better input shafts, stronger planetaries and wider bands, wide ratio gearsets, improved valve bodies and servos, etc. Whether it is worth the cost of the aftermarket bits and pieces to make it a desirable application is the real question.
