converting a transmission

[67 F100 in Richmond]

How difficult is it to convert from manual to automatic?
i have a transmission in my truck that is gear very low( for towing and pulling heavy stuff i guess)?and is a pain to drive that way.

Thanks.

its not real hard. you will need the transmission the kickdown rod the rear transmission rubber mount. the correct length driveshaft. you dont have to change out your brake and clutch pedal but lots of guys do. you will also need a automatic flywheel / flexplate. there might be something i missed i can't think right now.

with the truck 4 speed you're not supposed to use 1st gear unless you're pulling a lot of weight. Just use 2nd, 3rd and 4th. They were designed that way.

i just went the other way and put the 4 speed in... like Sideoilerfe said just use 2nd 3rd and 4th. I only have used 1st to start on ice and to pull into its parking space where it is a very short bumpy path and if you go to fast into it you will go through the garge door or the neibours fence.

havent used 1st once since i have had the truck but it seems that 2 is real short same with 3rd...
maybe i just need to get used to it more?

thanks for the input...

second on mine and keep in mind i have 4:10 gears in the rear... 2 i shift to third around 3000 rpm or so... and dependng on were in town i am the speed limit is 25mph so i stay in third at around 2000-2300 rpm.
I tried shifting to 4th but the engine bogged down something bad.

Yes the gears can be a little short but ultimatly its your truck so do what you want... though you might try driving the stick shift for a while... it may grow on you and if not you can always change it

Keep in mind that a regular automatic will drive te esame as a stick except for automatically shifting. The trans gear ratios are basically the same on an automatic and 2-4 on a stick. The amount of time in a gear may be short because of rear end ratio but the final drive ratio is 1:1 in all trans that are not overdrives. Hawkrod

What will seriously effect the length of time you stay in each gear is your rear end gear ratio. If you don't mind driving the stick shift aside from the fact that you have to shift so early, you should look at the tag on the rear end gear housing and see what it says. If it's got 4.10 gears and you don't haul anything significant or tow a heavt trailer you may want to consider 3.73 or 3.25 gears. It won't accelerate as briskly, but it will cruise at a more relaxed rpm on the highway.

Just for referance, my highboy has 4.10's and 33" tires, and I shift out of 2nd at about 15-20 mph and cruise at 35 or so in third. 60 mph brings about 2800-3000 rpms.

Sorry, and Thanks
i am more of a body/interior person not so much on the engine/trans/rear end.

So most likely the rear end gears are higher (4.10 or whatever) than what i need?
Thanks again for all of the responses..

It's possible. You can get the axle code off your door tag and check here: http://www.fordification.com/data-1967.htm . That will tell you. You can also find out what engine you have if you're still not sure.
