1965/1966 C4 shift linkage

I just had a 3ott to c4 conversion done on my 1966 F100. The bell crank mechanism that was installed does not allow proper gear selection.

I would like to purchase one from an FTE member if one is available.

I can be contacted by calling (913) 526-3106, or SjoDon1956@yahoo.com.

Are you talking about the manual lever on the transmission? Here is one "not for a truck" Ford Mustang C4 Automatic Transmission Floor Shift Lever Assembly KICK DOWN | eBay
If you didn't use a donor truck to source all the parts, steering column, shift linkage, kickdown linkage, neutral safety etc. you may need more than just that lever. Also to change that manual lever you have to remove the valve body from the transmission. If you are using a floor shifter you may get it working with less parts swapping. Also If you are trying to use an auto steering column for a 65-66 with an MX the shift pattern won't match.
A little more detail about what parts you used will help. Especially the neutral safety switch. Is yours on the transmission or the column?

Same question asked by the same user on the same day in the same forum. I'd call that a duplicate.

I saw that after the post. There was a bell crank used in the shift linkage in 78-79 trucks with certain transmissions. Still don't know exactly which part he needs. I suspect it will turn out to be more than one part to get it working.
Don, If it is the manual lever you need. I'm fairly certain that the C4 and C6 use the same lever. The problem is there are dozens of different levers depending on what they were used in. The one on the right in the picture is the one most common in trucks with the neutral safety switch on the column. The middle one is for a floor shift and the one on the left is a Lincoln cable shift. Also the kickdown levers are different depending on which manual lever it was used with.

I guess I will have to crawl under and take some pics. Thx

1979 Ford Fairmont 5.0,C4 trans, 1966 auto column from Flashback F100's (Tom said it is an original that he rebuilt).

I have found Jeg's 70486, and Lokar ACA-1801. The listings state each one will fit my C4 application.

Will either one be a gamble on fitment??

You had mentioned that currently you have to shift to Neutral and then to Drive. I was curious about that as it's generally a linear movement to go from Park all the way to Low (one extreme to the other) and it is just some detents that give it a sort of "click" into each setting. I wonder if you've looked into why it needs to stop in Neutral on your way to Drive? That almost sounds like something binding up. Or the detents are maybe not matching what you are expecting? Did Tom mention if this was a column from a C4 or a MX-COM? Crop Duster mentioned that in Post #2 which could be a factor depending on what the issue is.

Myself - I find it a good step to isolate the cause of something before looking for the solution. I'm a computer programmer by trade and in my field you don't want to go looking for the solution to a bug until you understand what the bug is.

It is for a C4 trans.

I have no idea if those aftermarket parts will work.
In order for the shifter on the column to work correctly the geometry between the lever on the column and the lever on the transmission must be correct. The manual lever on truck C4's and C6's is pretty much parallel with the bottom of the trans pan when the trans is in park. I'll bet that yours is pointing down.
Also like Chad said the detents in the column itself must match the transmission.

If the manual lever in your transmission isn't the right one here are a couple that should work. These are engineering numbers that are stamped on the levers not part numbers.
D3TP-CA that is the one I pictured. It works in a C4 or C6 with a column mounted neutral safety. If you can find a D3TA-KA shift rod to go with it should be plug and play.
E0TP-CA this is for a trans mounted neutral safety. But to use it will have to be bent upward about 20 degrees. These are the easiest to find and are still available new.
The neutral safety switch that will work with that E0TP lever is PN-D8TZ-7A247-A
Here is one on e-bay C4-C6 - FORD - MERCURY - SHIFT LEVER, EXTERNAL, CAST "E0TP-CA" - U36992G | eBay
Changing one of these isn't difficult but it is a miserable job with the transmission bleeding to death on your head.

Can you give me an idea of the years those parts would fit.??

Those levers will fit any C4,C5,C6 or AOD as far as i know. I was just giving you some direction with parts that I have used and will work. See if this describes your problem in the simplest of terms> The shift lever indicator does not line up with the gear the transmission is in?? If that is the problem then the manual lever in the transmission, is the wrong length or the wrong angle or both.
Unless you can find a donor truck with the exact parts you need, you will just have to make do. The thing that most people don't realize is almost every car and truck over the years had different shifter arrangements. and in your case with a transmission from a Fairmont it just doesn't play well with a truck column.

Just go to this page and you will get an idea of just how many different manual levers there are. And this is only the tip of the iceberg. They do show a D3TP also.
