Hey there everybody, so I just picked up a 1964 Econoline Heavy Duty, and I'm trying to identify my motor, pretty sure it's not the original 170 that it came with. I'm new to fords, and am having trouble figuring it out. I'm thinking it's a 240 or 300. The numbers on the side of the case are e1te-6015-aa so I know it's a 1981 truck motor, but that's all I can figure out. Also, the tranny isn't shifting into 3rd gear. The fluid didn't smelled burnt, but I went ahead and serviced the transmission, replaced fluid, and replaced the vacuum modulator, but still no 3rd. Is it time to rebuild or is there something else I should do? Thanks for any help, it will be greatly appreciated! Here she is, hopefully somebody out there will be able to identify it from just looking at it.

 

I should add that it has the original c4 in it.

 

Big six from '81 would be a 300 if the rest of the motor matches that number.

 

Regarding the trans, check the vacuum line to the modulator, make sure it has vacuum.

But first, what does your shifter quadrant look like? Prior to the "Select Shift" in '67, these were called "Green Dot Cruise-o-Matics" by some. Note there is a "." after N, then the Greed Dot. You drive and get all gears in the Green Dot. The "." starts and keeps*** you in 2nd gear.(no, see below. starts in 2nd, shifts to 3rd)

You might look at the trans--if it is '67 and up and you are in the Green Dot, you are actually in 2nd gear. Scroll down here and see examples of both in the console shifters. Column lines up the same as you see in the above image. A newer trans with the old shifter is pretty easy fix, so good luck on that!

Otherwise, back to the modulator, lines, etc.

***the "." starts you in second, but does allow a shift to 3rd. That's why you thought you didn't have 3rd, as you got a shift out of it. The '67 and up "Select Shift" models would start and hold 2nd when started in "2". You can bring that valve body over to the older trans if/when you run out of everything else you have planned.

 

Thanks for the info. I'm about to leave for work, if I put it into the green, and everything works fine, I'm gonna feel real dumb. Lol we'll see.

 

Okay so, yeah. I was starting out in the wrong position... like I said, I'm new to fords. That being said, the thing is shifting into 2nd at 5 mph, and 3rd at about 20 mph. That seems too low. It appears that somebody has removed the kick down linkage from the tranny. Would that be causing the low shifts?

 

As you can tell by my repeated reliance on links, I am no transmission man.

However, that trans is controlled by a couple different things.

There is an internal governor, which I think works off hydraulic pressure.

There is the modulator, which helps regulate hydraulic pressure inside the trans. It can be adjusted:

And there is the kick down linkage. For WOT or even mid throttle shifts, you must have that linkage or it will shift way early.

Your shifts seem correct for light throttle.

 

300 I-6 swapped in 1964 Econoline that never came with it originally. 1981 300 would have a C6 (or AOD) while 1964 Econoline would have had a C4.

Stuffing that 300 in there probably left no room for the kickdown linkage or it wouldn't fit.

 

His picture shows a C4--bell is bolted to the main case. His '64 HD would have been a 240 right? Same convenient size as the 300.

C4AP-7006 is visible on the trans case. Kick down linkage attachment point is vacant.

 

No H/D Econolines (Super Van) until 1965.

C4 trans is probably the original, has a 1964 case ID number that crosses over to C4AZ-7005-D

 

OP said HD in first post. See first sentence in post 7. Were there 240s in '64?

 

My 1964 Heavy Duty (1-ton payload), not a SuperVan, Econoline came with a 170 engine. The 240 was not available until 1965.

 

Does the transmission have a single bolt holding up the rear of the transmission or two?

 

He has a picture in post 6. You can see part of what might be a mounting bracket at the top of the trans. Is that what you are looking for?

 

I can't quite make it out. It's either a single bolt parallel to the axle or two bolts parallel to the driveshaft.
