For the shifter shaft bore I would just lightly smooth out the rough edges on the outer edge and the gouge in the inner chamfer with a red scotchbrite pad to prevent them from causing a knick in the new seal when putting it in and you should be good. As for the "maze" there's nothing to worry about there the case is cast aluminum which will never be 100% perfect and the chips were probably there from when the housing was cast and the gasket surface was first machined. It looks to me that the gasket surface is still nice and flat and not all pitted or have any low spots the could create any internal leaks within the valve body.
I'm just about ready to start putting it back together. I'm wondering about what kind of trans fluid to use. Just regular store brand should be OK, right? Or should I look for something better.

So it's not normal for the rollers to fallout of the low one way roller clutch, correct? I'm assuming I should replace it.
You can just put them.bsvk in as long as the little thin spring that pushes then isn't missing or damaged
So I'm working on the output shaft assembly and there's a couple of things. The outermost gear (speedo gear?) looks OK except for the end which looks to have a very rough surface. Almost like something cracked off. That being said the teeth look OK and there is a very nice looking chamfer where the teeth end on that side. Kind of looks like a factory screw up they let through because it wouldn't affect anything. Second issue is the new bushing I got is taller and has a couple holes whereas the old one is shorter and has no holes. Both bushings have the same style ID lubrication grooves. BTW, the new bushing still looks like it will fit.
I found out the taller bushing is OK and actually preferred. Next the forward gearset has some light grooving on the outside diameter. Not sure if it needs to be perfectly smooth or if that's OK.
So pictures of questions. Like this help, one idea of light grooving can be different. Plus it helps show exact locations
This is a picture of the OD. Hopefully you can see what I'm talking about. There's a lot of stuff that has marks but you don't feel anything when you run your finger against it. This you can feel. This a picture of the side of that speedo gear BTW.
On that geat set, those circular Mark's are caused from the gaps in the low/reverse band. You nothing to worry about, if you want you can take a scotch brite pad to the outside to knock the glazing off, just clean it very well after to make sure nothing stays inside or tiny gritty parts are left, especially if anything gets in the pinion gears Never seen a speedo gear like that, but they ate easy and cheap to replace
I've been busy lately with other things, but I finally got some time to work on the trans so here is an update. The gearset and the center section have been cleaned and gone thru and are back in the case. (how's the positioning of the snap rings BTW?). Very soon I will be coming to the things that need to be modded. Man that low one way roller clutch was a bear to get back in. The rollers kept falling out, but after the application of some expert profanity I finally got it back in. Also very pleased I was able to change the center section bushing. That thing is like 6" long and I thought I wouldn't be able to knock it out. Fortunately I found a socket that was just the right diameter and I pushed out the old one. Next the clutches!
Stop......that snap ring needs moved.......I circled yours in single red circle. You need to move it to where both ends are tucked under the lugs,,,,,,,like over where the double red circle is. In fact anywhere as long as vith ends are under the case lugs,,,,,not one end just open and flexing. See yellow line,,, as long as both open ends are in the yellow area you will be ok.......I prefer to center it as much as possable This goes for all snap rings in this area of the trans
Thanks, I appreciate the expert eye. I will adjust. Different topic - the kickdown solenoid. I actually have two to use but on both of them the insulation on the wire is cracked and coming off. I assume I need to get a new one?
No expect here......if the solenoid still functions, I would guess some liquid black tape, or some wiring shrink tube should keep anything from shorting out
That look nice and clean. I believe the early solenoids were about 18 ohms, but later somebody decided to save wire by making them (less efficient) 10 ohms. I prefer the early, some I have been able to use a replacement tefl-n wire on. The problem with that steel speedo drive gear, is it is very difficult to change in the car. I would take this opportunity to replace it with a plastic gear, which can easily be changed as needed to calibrate your speedo. Bruce Roe
OK, new problem. I'm preparing the intermediate clutch pack. I've measured the old clutch/plate stack up height and the new clutch/plate stack up height is something like 0.030" - 0.050" taller. Could this just be because the old clutches are worn? By individual clutch plate the new clutch plates are 0.010" thicker.
You are test fitting and measuring the tolerances dry right? You may have to swap a few clutch plates back and forth to get your tolerances right. I ended up having to use one of my old steel plates to get my tolerance right. Just make sure if there's any burnt spots on it to sand the plate evenly not just on the burn spots to clean it up and reuse it.
The new ones I'm measuring dry. The old ones I didnt bother to clean because the will go in the trash once I'm done with this part. I really am thinking its wear because the old steels are like 0.002" thinner than the new ones. BTW this clutch pack has a larger OD than the others. So my kit only has 3 and 3 of that size. No swapping around here possible. Finally to keep the wavy plate or not? Still deciding...
Yes they'll definitely be thinner due to wear. Sorry my apologies you said intermediate clutch pack, yeh that's different you kinda gotta use what you have in the kit. I had the same issue with mine and the tolerances being bigger than what the specs say. Ben said the same thing to me it is what it is and that it should be fine as it's not as important to to stay right on specs with the intermediate as it is with the direct drum. Maybe he'll chime in to reassure what I've said is ok.
