Transmission completely went out. Bought a transmission from wrecking yard, worked great for 10 miles. In the morning the speed cable was leaking transmission fluid really bad. Stopped shifting out of first. Filled fluid and it still wont shift up from first and started shifting hard. If I repair leak will it start shifting?
No. Buying a used transmission is a gamble. It is like getting your hands on the original transmission just 10 miles before it went out on you. And they usually do not carry any type of warranty.
I recommend a re-manufactured engines and transmissions that comes with a parts and labor warranty.
