I recall this process from when you first started this thread. You're a brave man for taking the task on again.

I bought a Harley several years ago. I spent months just getting it to run right. I remember coming home from a ride one day and saying to my wife "Good news Honey, no parts fell off this time." It sounds like you're way ahead of that.

A few small updates. The transmission works like a top. However, the new yoke that I bought on Ebay is leaking through the press in fitting at the back of the yoke. My floor is now fully rust proofed :(. I put the car in storage. So, that will be first on my list when I get her back out in the Spring. I did some work on the shift quadrant to get all of the "R's" and "D's" lined up. Obviously the Dynaflow and the ST400 have different shift patterns. Not perfect, but pretty good for hand painted. I think it will look better when it's on the car. Also, putting the finishing touches on the this. My inner 12 year old just had to have it.

Also, it looks like it may now be owned by a family of vampires. Bring garlic and a wooden stake.

Does that mean you're not allowed to repair damage and wear? Unfortunately terminology like this can be vey subjective.

What are you referring to?

So when do you start the engine rebuild?

$121,000, wow!!

Short of going out to the garage and measuring axle width and wheel well opening yourself, I don't think anyone will really have anything to offer. There seems to be little knowledge about these cars; especially as it relates to custom options. I measured WMS to WMS on my 62 last year. Mostly this was for a possible axle swap. I came up with 60 3/4". I know that oftentimes the 64 Rallye wheels are used. So they work. Using that offset may be a good starting point. Be aware that these cars are lug-centric mounting versus hub-centric.

I don't have any advice to offer. But I do have a complement. That is a beautiful car. Even with those modern wheels, it looks really good.

So it isn't a Dynaflow? What doe the "G" stand for on the shift quadrant? I've never seen that. Granny gear?

He didn't say. I still have a torque converter to pick up from him. I'll ask him when I see him. He did mention that the "early" 4L80's interchanged. I think there was a short period where they weren't electronically controlled. Maybe that's what he meant. I will ask him to clarify.

When I was in my 20's I looked down my nose at those old boats. Now on the other hand, I can really appreciate them. Some cars from that era are aging quite well. Or maybe I am :).

So the 2nd band for a 4L80E is also correct for the TH400?

Not exactly. A TH400 is a 3L80 (3 speed). A 4L80E is a 4 speed with electronic controls. For the second band that I bought, it was listed as being for both. The trans guy said it was wrong and could tell immediately that they were different. He told me that the early 4L80's interchanged. Maybe that was before the "E" came along? I don't know.

Progress report. I got the transmission back. He re-shimmed the pressure regulator. He also found that I had installed a 4L80E 2nd band. I recall when I bought t he second band replacement that it said 4L80e/TH400. Live and learn. These are the things that come with inexperience. I also am pretty sure I wouldn't have noticed any of these things had I taken the transmission apart myself. I didn't notice it the first time anyway. I'm still glad that I went through the transmission and rebuilt it myself. I learned a lot about how automatics work. It's always been kind of black magic to me.So, I got the transmission in this weekend. Everything works! The car runs awesome and shifts great. I spent some time modifying my shift linkage and it's all spot on. I think I have some fine tuning of the carb to do. I got it setup before the rebuild, but I think it's talking to a different engine now. Plenty of power, but I just want to tweak it to get the most out of it.I have to say with the Bruce Roe controller in there, the transmission is every bit as smooth as the Dynaflow was. I'm really glad I put this transmission in and it wasn't that hard of a swap.Now it just needs to stop raining I put about 30 miles on the engine this weekend. I need to take her for a long drive.

Is that a bad thing?

Hi, I didn't see it mentioned. Did you have the block sonic checked?

PM sent

I would think if you really wanted to "Spare no expense" you would have rebuilt the nailhead.

I just talked to the transmission shop. They sent the converter off to be checked out and it checked out fine. I found that kind of baffling given the symptoms. But I am not a transmission expert. I dropped that transmission off too. He found that there was what he would consider to be an excessive amount of shims in the pressure regulator. He's thinking that this may have kept the trans from actually filling the TC. He isn't really finding anything else wrong with the transmission so far. He's going to go the rest of the way though it just to be safe. They're going to reassemble the TC. It's been about a year since I rebuilt the transmission, I'll have to check my notes about why so many shims are in there. It could be that I put it together backwards too. Hopefully this is the issue though.

I remember hating mid-70's cars when I was a kid. They've really started to grow on me these days.

Looks like a Nailhead to me.

That's a fine looking car.
