I got the aod installed done about 2 weeks ago/ I can't belive how well it runs with a 3.10 rear gear /at 70 mph I run 1700 rpm I was sure that I would have to go to a 3.50 and run around 2200 rpm/go's up most hills great with no kick down/ Im getting 18mpg instead of 13mpg at 70 on interstate type driving, but I got $2700 in it and thats with me doing all the work also also includes a new 9 inch rear end/at $3.50 a gal gas it will paid back in about 34k I only drive it around 5K a year but its nice not listening to the y block run 3000 rpm with the old fom/if anyone out there is think about doing this swap I now have most of the answer were before all I had was question / I do question if it was worth that much money

Sounds great. I'm running a 3:80 gear and in the high 2800 realm at highway speeds. Did you set up the TV cable with a gauge? The exact pressure is critical. If the pressure is off an AOD can burn up in a matter of blocks. Just thought I should check. Chuck

yes used a gauge also used a lokar tv cable and tv arm on aod

Did you use the Bendtsen (sp?) adaptor for the swap or something else? I see by the earlier post that it was Bendtsen

I've never found anyone that could give me tips on "tuning" the shift points with the TV cable. Most just say to fiddle with the adjustment nut and see what changes it makes. Not too much though as you don't want to throw off the pressure by much. Anybody got any tips? Chuck

Yes, i gather you're supposed to use a pressure gauge to set it, according to the Ford people anyway. All I ever did on the Ranger was make sure the lever started to move as soon as the throttle moved off the idle screw. Worked for 12 years!

The factory style TV cable was sort of preset in the upper retainer so they are usually pretty close. The problem is in a modified application. You are starting with an new trans, new TV cable and some sort of carb adapter. Lots of room for error. That said, once the pressure is correct removing the cable attachment at the carb dosen't require re-adjustment if you left the cable retainer alone. Rattle, rattle, there I go. Anyway I really like my AOD. The Hemi I bought has a modified 700R4 with it so I guess I'll be back on the learning curve for that one. Chuck

AOD transmission. It is hydraulically controlled and a TV valve in the valve body meters pressure to one side of a valve in the valve body and acts against the pressure delivered to the opposite side of that valve by the governor on the output shaft of the AOD. Governor always see vehicle speed and from where the manual valve ( shift selector, gear shift lever as in manual low or drive or reverse ) the gov knows what gear the transmission should be in.
IF TV VALVE IS IMPROPERLY SET LOOK OUT, TOASTED TRANNY
The TV valve is connected to the gas pedal. More gas more TV pressure. Enough pressure and TV valve will overpower gov pressure and cause a shift.. Do a google searce, lots of info out there. CAUTION its not all right.
Different carbs need different attachment points for the TV to maintain the ratio of gas pedal motion to TV valve travel.
A reliable link to TV valve adjustment start here http://www.becontrols.com/tvlinkage.htm
A forum I like is click click racing. Pete

adj it is easy buy a $20 oil gage at parts store and installed on test port /the line that comes with gage will let you see the gage when your doing the adj /what your looking for is 0 a idle and 35 to 40 psi with spacer installed on cable/ takes all the guess work out ot of it /also if you are using a ford oem tv arm you need a throtte corrector on newer holleys or edelbrock carb./the lokar tv arm has the correcection build into it

Nice, it should have been an overdrive, lock-up automatic already in 1955 (and 12 volts). Do you have pictures of the installation? Is it a stock engine otherwise? Have you tested fuel consumption at lower speed, e.g. 50 mph on third gear and lock up? Just curious, because my stock 1955 292 with 3 speed and O/D gives 21 mpg at 50 mph. My 4.09 rear end means 2100 rpm at 60 mph.

sorry no pictures/car had a air cool fom with 6 v sys when I got it/engine runs good but I think its stock/ when the weather gets better Im going to what see what kind of mpg I can get at 50 and 60 mph but I don,t think it will due 20

Kansas,
Shortly, I plan to install an AOD in my mainline ute. Just wondering what cooling did you use? I have a radiator with a cooler but I planning on using additional cooling.
I should have a heap of question but I think I've researced the hell out of this.
Cheers
Warren

I wouldn't think another cooler would be necessary. I'm using the one in the radiator on my setup. It wouldn't hurt to run a second one I guess. Chuck

moonshadow,
I though that runnning a additional cooler was resonably common place with modified trans or engines. An AOD in a car not originally designed for one is a modification. I have a cooler in my aluminium radiator but I don't know it's capacity/capability.
If Kansas has installed an after market one, his creativity may give me some ideas.
cheers

Howdy,
There might be a disadvantage to running an additional cooler. You do want the transmission to run "warm" not hot of course.....but certainly not too cool.
The 4L80E in my 94 3/4T Suburban will not "lock" the torque converter until the trans (oil) temp gets above a certain point. I have two coolers on it and in very cold weather, and not towing a load, it takes for ever for the trans temp to even register on the gage!
I'm going to run a rather large cooler (with it's own fan) for the E4OD in my 55 F-600 but I am going to watch the temps fairly closely. I suspect that when I am running down the road "empty", at a constant (TC-locked) speed, it's going to run very cool.
When you don't tow or carry rather heavy loads and you have a locking torque converter, an automatic transmission will not generate all that much heat.
Maximum heat is generated in an automatic trans when the TC is not locked and you're pulling a load or during full throttle runs up a hill (TC-unlocked) . Other times when the TC is locked like going down the road at constant speed, or going down a long hill, the trans will not make a lot of heat.
If your trans is in a small car not pulling a load, you're not going to need a whole lot of cooling.
Cheers,
Rick

Rick,
You've made some good points. I had'nt considered lock up as not providing as much heat. I had though of monitoring it but disregarded it as something I wouldn't do long term.
If I were to buy one of those laser thermometres it would be very easy to point that at the pan from the side of the car.
Transmission coolers seem to be based on car GVM, there's a thought that a radiator, that was made for the car, would have a cooler to suit. I would like to run a aluminium pan there are a range of sizes. Many have baffles which not only stop slop but increase surface area for cooling. An increase in oil capacity would increase thermal mass and increases in temprature would slow.
Cheers
Warren

I replace old radiator with one that had cooling build in I was also going to installed a inline cooler too ,but I had 3 different transmission shops tell me I would be fine with just the radiator cooling/I will know more when it gets hot

whose kit did you use and can the starter be replaced without pulling the trans one co. says put starter on adapter then install it to the motor got me to thinking

I used BENDTSEN kit / starter can be replace with out pulling transmission
