1984 C5

[Ruffinit]

Sooo... I've been driving my BII for the past 2 years in mostly winter weather commuting 140 mile/day. This morning it threw a rod.

Question is; what is a good C5 worth? What is a good C5 with a good transfer case worth?

I'm keeping the BII to put the drivetrain from the '94 Exp in, but it's 8 degrees and the snow is up to the bumpers so it'll be a while..

[Ranger Dave]

does the converter lockup??

[Ruffinit]

I thought that only the aftermarket T/Cs locked up on the C4 and C5. This is a totally stock '84. If that is not correct I have no answer.

[Ranger Dave]

the C5 is a lockup,the C4 never was. you cannot buy a lockup converter for a C5.

so i take that as a no,it doesnt lockup. you would know when it locks up. you must go through some gas without the lockup driving 140 a day

[Ruffinit]

I do not believe that the TC locks up. Normally you can feel when one does. As for the fuel mileage; the '84 during normal winter driving will get between 16 and 18 mpg. My '88 was getting similar mileage during the same type winter driving. Both of them use the same tire/wheel set and the tire size is 235/75 15 Goodyear Wrangler. I don't drive the BII back and forth when I can use my 4x2 Ranger which gets far better mileage. Believe me when I say that with a 140 mile/day commute and the price of gas I know what the mileage is. My avatar is the '84.

well the clutch is burned up in it

my 88 gets 25 if i drive it easy

Sure, that's easy to believe. My '88 got 24 mpg in the summertime, on the highway, in overdrive. The '84 gets what I consider fair mileage at 21 mpg in the summertime, but that's a 3 speed w/o overdrive. All internal combustion engines get worse mileage in the winter when the temp is between 0 and 20 degrees.

So... any idea what the C5 is worth? Even IF it had be rebuilt? I had a '79 1/2 ton 2wd pickup that had a C5/400 in it. It's far stronger that the newer overdrive automatic trannys, but you already would know that. I'd hate to scrap it, but I'll not put it in anything else. When I put the 4.0 in, it's already got a 5sp mated to it.

the C5 didnt come out till 82,that 79 had a C6 in it

the C5 is worth what someone is willing to pay for it. most C5's(and all the ones i have bought(i have 5 of them) except for one,the clutches were gone/toasted)all need a rebuild. the rear shaft and adapter is what people would be looking for cause you can put them in a C4

[Ruffinit]

Well Dave, normally I would take what you say at face value, but for some reason you seem determined to pick a fight with me on a simple question...

First off you should check your sources, the C5 was NOT introduced in '82. The following vehicles had the C5 in it:

1973-83 F100. Early 80's 4WD Rangers w/V6s. 1973-81 F250. 1982-83 Fairmont. 1983-86 LTD.1977-78 LTD II. 1976 Maverick.1982-86 Mustang. 1972-77 E series.

I did not have a C6 in the 1/2 ton I owned. Maybe you better stick to Rangers. You needn't bother replying.

[Ranger Dave]

what ever you say. the csating numbers on a C5 start out E2= 82. so how could a 79 have a 82 tranny it.

Hey Ruffinit,

I don't know where you are getting your information from but if you check your claims out you might learn something.

Dave is very knowledgeable and he is also 100% correct about the Ford C-5 Automatic transmission!

Here is a FACT for you. Direct quote from a source:
"1982 brought the C-5 which was essentially a stronger C-4 with a centrifugal torque converter lock-up clutch and an enhanced valve body for smoother shifting. It was produced through 1986 and was completely replaced by the AOD".

That fact was so easy to confirm it took less than 3 minutes by simply checking known confirmed sources of information like a public library online.
*********************************************************
Oh here is a list from another site explaining what was when and now.

* The FMX/Cruise-O-Matic three speed evolved from the 1950’s Ford-O-Matic and was used until 1980 when the AOD was introduced.

* In 1964, the C-4 was introduced, providing a lightweight and durable three-speed automatic which is a favorite among racers today. The C-4 was produced until 1982, when it was replaced by the C-5.

* The C-6 appeared in 1966 as a heavy-duty unit primarily used behind big-block engines or in large vehicles. Internally, it is much like a scaled-up C-4. The C-6 is still used today in certain truck applications.

* The French-built C-3 was first used in 1974 in the Ford Pinto and remained until the Merkur XR4TI was dropped in 1989.

* The Automatic Overdrive (AOD) transmission was introduced in 1980 as Ford's first four-speed automatic overdrive transmission (a.k.a. AOT or FIOD in some literature). Internals are loosely based on the FMX. The AOD was finally replaced by the AOD-E/4R70W in 1994 for all remaining applications.

* 1982 brought the C-5 which was essentially a stronger C-4 with a centrifugal torque converter lock-up clutch and an enhanced valve body for smoother shifting. It was produced through 1986 and was completely replaced by the AOD.

* The A4LD four speed overdrive transmission was introduced in the 1985 Bronco II/Ranger and saw use behind many 4 and 6 cylinder engines until the 1995 model year when it was replaced by the 4R44E and 4R55E electronic transmissions. The A4LD was the first Ford transmission to use an EEC-controlled torque converter lock-up clutch and later became the first to use electronic shift control (via a 3-4 shift solenoid). The French-built A4LD was created by adding overdrive to the front of the C-3 three-speed unit.

* Full-size trucks first received the huge E4OD (Electronic 4 speed OverDrive) transmission in 1989. Internally, it is essentially a C-6 with overdrive added to the front (such as the A4LD is to the C-3) and an EEC controlled valve body.

* The AOD-E transmission first appeared behind the 4.6L modular V-8 engines in 1992. Essentially a beefed-up electronically-controlled version of the AOD, the AOD-E also includes a new and stronger wide ratio model (the AOD-EW or 4R70W) which was introduced in the 1993 Lincoln Mark VIII. The AOD-E (in both standard and wide ratio versions) completely replaced the old AOD in 1994 with a new case that mates to the 5.0L and 3.8L engines.

* For 1995, the 4R44E (4 cyl. - light-duty) and 4R55E (6 cyl. - heavy-duty; i.e. Explorer) electronically controlled transmission replaced the A4LD. It is mechanically identical to the A4LD.

* Later, the 5R55E was introduced behind the 4.0L SOHC V6 as the first domestic five-speed automatic. Mechanically similar to the 4R55E, the 5R55E uses revised controls to leverage the mechanical capabilities of the 4R55E to deliver a fifth forward speed.

Actually Tek, I had double checked what I said after Dave's first comment. I doublechecked with FordTrucks.com, Racetransmissions.com, Autorepairmanuals (Ford C5 Transmission Repair Manual) and doublechecked that the W code was a C5. I could really care less though about the heritage of an automatic transmission in a truck that I had 20 years ago. It was an F100 and had a tranny that looked like the C4 in my wife's Mustang Cobra, except it was a deeper pan. Same number of bolts.

All I was asking for was what the tranny was worth so maybe I could get a couple bucks out of it. That's all. What's the deal?

[Ranger Dave]

the tranny in the F100 or f150 was either a C6 or a FMX

well maybe you should, then you wont post stuff thats not true

I had a '79 1/2 ton 2wd pickup that had a C5/400 in it.

I'm not arguing with ya, just make sure what you post is right. the chit has happened before. some one posted to use a certin flywheel with a C5, so that person did and broke the front pump in the tranny

[Ruffinit]

Well, I can understand that... I would want to be the last person to mis-lead someone.
So the stock configuration never included the C5 which doesn't mean that it didn't have one in it. I'll have to go back to the Ford dealer in Bremerton and let them know that they were wrong along with these other resources. But I'll guarantee that I have an '84 with a C5 (that may or may not have a functional locking TC) and 2.8 with a thrown rod. I also have a '67 410 Merc in a '69 F100 and a '65 E100 pickup with a 170 (it's stock) and an '89 F350 with an 351M... So MAYBE, just maybe the '79 wasn't the stock drivetrain because I don't think the F100 came with a 400 either, I believe only the F150 did. So I may or may not be wrong. My brother had a 225 slant with a Toyota tranny in his '70 F100. He also has a single barrel carb from an 883 on his Suzuki 4 cyl bike. No one here would ever put anything in a vehicle that it wasn't designed for.
So.. is it possible? Yes.
