After I changed my th700 to a th350 my speedometer began to jump whats the problem how do i fix it? The speedometerwire i brand new. It works when i drive 50 mph and over.

 

Are the drive and driven gears compatible?

 

I do not know. what type of gears should I use? I'm a newbie to this.

 

The TH350 gear housing isn't the same size as a 700R4, IIRC, so if you've swapped in a TH350, there would be a problem. Here's what you need:

i wont speak for compatibility, but the cable needs lube. graphite lube for lock cylinders will work. its a dry lube

 

I used white lithium grease, on the speedo back where the cable hooks in and I also shot a decent amount in the cable using the straw but it sounds like you should follow james advice, even if you lube it you still need compatible parts

 

In the following link there's a procedure for cleaning and lubing:
