I think the problem may be I was sold the wrong trans . I noticed a leak from front drver side axle . After some investigation I noticed that my original axle wouldn't fit in the new trans.
Here are some numbers from both transmissions . I've tried Google for both numbers found nothing. Thanks in advance for any help
