TH400 Leak fixed..new problem. Please Help.
I was finally able to get my TH400 to stop leaking. It was the speedo housing o-ring and speedo gear drive seal. Well I replaced those and it stopped leaking. Great... So I thought.
After a few miles with a smile on my face I noticed my speedometer making a winding noise. I removed the speedo cable from the dash and the noise was still there but not too bad. I thought it was the speedo so I grabbed a known working speedo from my stash and it still made the noise but not as loud. Next I removed the Speedo cable from the truck and removed the cable to clean and grease it. When I reinstalled it the noise was still there but not as bad. I am leaning towards the speedo gear housing being the problem but visually the housing and gear look fine. It seals so no leaks. Has anyone had a similar problem like this before. I want to get this issue resolved because my 17 year old nephew has been asking me all winter to let him use my truck for his prom. Well I agreed and his prom is this coming Saturday.
