Guys, ive had this problem for a while.
Used to have a th350 in my truck. With this tranny, the speedo needle would go back and forth about 10-15mph from my acutal speed. It would also make a squeaking/bad cable noise, but the cable is new and lubed.
I swaped in my new 2004R tranny. When they shipped it, I gave em the info and they sent the correct gears. 255/60/15 tires and 3.54 gears.
I told them 3.54 because I THOUGHT I had a th350c, and thats what my rpms to speed calulated to be. I really have 3.42 gears.
Now the speedo is off about 10mph, and every once in a while it will sweep back and forth, but no noise. Whats wrong????
