TH400 Transmission GURU's Please help.

[petey-pablo]

I have several questions My th400 was put together with the wrong yoke so it caused some problems.
#1. My first question is does this little copper ring that slides over the yoke supose to fit in the Transmission Tailhousing snug or loose?-Mine fit's loose What is stoping it from moving forward and falling deeper in the Tailhousing and bouncing around?
#2. 2nd question Where can I buy a cheap non fancy Transmission Tailhousing if I need one?
#3.Question 3 my input out put shaft( I hope thats what its called) looks all scratched up & worn because of the yoke being the wrong one Does it look like I need to replace it?
#4. Question #4 Do I have the correct color speedometer gear for my transmission and rear end set up it seemed a little off when I drove it, I have a 12 bolt with 373's.?
I just had a new drive line made with the correct fixed yoke and I am short on funds you can say I am broke so I am hopeing I can get away with just replacing the Transmission Tailhousing if I need to thanks Pablo....Here are some photos
#5. Also what can I use to clean the inside out when I get ready to close it up can I use brake parts cleaner?




Thanks guys...............
