Went to change the fluid and filter in the TH400. I noticed that the fluid running over the pan into the catch can was bright red and very transparent with the bright sun's light in the background, I'm thinking it's too clean.
When I removed the pan I noticed the filter was hanging but the bolt holding the filter was tight. I don't think the filter was catching the fluid. It wasn't connected to the return tube. The nut you can see in the photo is in place and it has an unthreaded shank nearly 1/4" unthreaded. The hole for the filter is much too large for this bolt.

Also, there is some sort of sensor on the driver's side of the Trans (see photo) you can see what it is attached to on the other side. Anyway, that sensor has a brown or black wire with a tan colored tracer and the wire loops over the top of the Trans and stops there . . . . Not connected to anything. What is it and where should that wire go?
Is that filter hold down bolt the wrong one, if so is there any part number?
The first photo shows a silver oval casing on a 45 degree angle on the left side of the photo, it looks like a relay and has a red wire leading out to a sensor looking connection.
The 2nd picture shows the unplugged side of the sensor as mentioned about the 1st photo.
The next 2 pictures show the bolt that should have held the filter "See the bolt next to the Teal colored #34 stenciled on the valve body"

I added some new descriptions at the bottom of the first post.
Thank you for taking a look at this.
 
Could the trans come from a Buick. The picture below and the info that follows is from this website.

Contrast the single wire on the standard TH400. Apparently what makes the switch pitch special is
it has two stall speeds on the converter, activated by the switch. Only Buick used these from the factory,
but they apparently are desirable to the race crowd.
 
I was thinking that "sensor" as I call it is a kick-down. If that is the case then, is this year car supposed to have it behind the foot throttle or on the carburetor? What you are suggesting is way beyond anything I know about.
 
I have to get the numbers off the Trans to day. I don't want this car crippled over this filter issue.
 
Oldsmobile used the Switch Pitch Turbo 400 in all 1965- 1967 425A , B & C 425's.
Olds Delta 88, Delta 98 , & Startfire had the Switchpiitch Turbo 400.
 
Brian, are you saying that this is an Olds switch pitch tranny? If so, does that lose wire go to something behind the gas pedal or to the carb? What does it go to on the carb? (if it does go to the carb).
 
I asked a rather large and well known transmission shop to decode the numbers on my trans last week. Not hearing back I checked today. It's from a 1970 Buick GS Stage 1. It must have some value because the owner called me back and said he could install a rebuilt correct 1968 Pontiac TH400 in exchange, nothing out of pocket for me plus a 3 year warranty.

Dont do it Richard .
A 1970 Buick GS STAGE 1 TURBO 400 TRANS REAL DEAL IS WORTH AROUND $5,000.00
 
Oh, Hell no! I wouldn't ever do that!
I just wanted get that dam kick down/down shift wired correctly and to do that I needed to ID the trans. I got the wiring schematic for the Stage 1 and it looks good.
The Black w/orange wire goes to the bulkhead connector on the engine side of the firewall, which allows it to pass a fuse in the fuse block under the dash.
The weather is letting up a bit this weekend so I'll fix the non-working A/C so I can get some daytime driving in. Next would be the exhaust, sort out the slow moving top, replace the cheeky weather stripping, tackle the bodywork and get rid of the under the dash stereo. After that it's just busy-work.
