clueless 3,012 #1 Posted October 30, 2016 Doing a trany swap this weekend on the '87 312. The new to me trans is off of a 2003 315-8, 8 pinion 1/1/8 axle with a little over 600 hr. It was drained before I got it but what little oil that did come out looked good, no mud. Just finished running it for about 20 minutes thru all the gears with a Qt of kerosene and a Qt of 90wt, drained it, stuff looks good. Should I do it again or or just fill it with oil and use it? 1 Share this post Link to post Share on other sites
stevasaurus 22,882 #2 Posted October 30, 2016 If it came out clean...I'd go with it Chris. What is wrong with the old one?? Share this post Link to post Share on other sites
clueless 3,012 #3 Posted October 30, 2016 Yea Steve, that's what I'm going to do, might drain and fill it again this time next year if it looks a little muddy, tractor does not get a lot of uses. The old one slowly developed some loud clunking in the front of the trans soon after I bought it from the original owner, he had just changed the oil when I got it. Its been about year and a half since you guy gave me your thoughts, and eventually decided I would have to tear into it, too many other projects so it went on the back burner. Got a good deal on the new one, thus the swap. 2 Share this post Link to post Share on other sites
