88 jeep wrangler with np231 is leaking fluid into speedo cable. Took the speedo gear housing apart and there is a small rubber seal that I think is the problem.it is not a regular o ring. Does anyone know where to get it?
Well I have replaced the o ring twice and after about 15 miles it will pump fluid onto your feet. The vent tube is clear.Anyone have any ideas? I don't know what to do from here.
