Im in the process of installing my tko600 / lakewood scattershield/bellhousing and I have a couple of questions. (1) is it ok if the bolts that attach the scattershield to the plate between the scattershield and block on the very bottom rub against the oil pan? My concern is will this eventually wear a hole in my oilpan? can I leave the lower 3 bolts out and all will be ok? Im running a roadrace type pan and the distance between the mount plate and oilpan is the same as the thickness of the nut. My other Qustion (2) is when installing my transmission in to the scattershield there seems to be an interference fit between the hole in the scattershield and the flange located where the input shaft meets the case. Is this normal? Any help here would be appreciated. Thanks. Jay.

I had the same problem. The best solution would be to install the bolt in the opposite direction since the head of the bolt is usually thinner than the nut. However in my case that would've meant pulling the trans or the oil pan which I was unwilling to do. I ended up locating nuts that were thinner at a local hardware store. I guess you could also grind the nuts down to an acceptable thickness. I also had to grind down the length of the bolts about 1/8". I wouldn't leave them out.

It's more of a slip fit than an interference fit. The tolerance between the trans locating ring and the opening in the scattershield is pretty tight. That, plus the fact that you have to precisely line up the end of the input shaft to the pilot bearing, sometimes makes for a very interesting installation process. If you have a manual clutch (i.e with a z-bar and pivot fork), have someone press the clutch pedal to the floor when you're installing the trans. This will allow the clutch plate to move freely and ease that last 1/2" engagement of the input shaft to pilot bearing.

If you used the four bolts that mount the trans to the bellhousing to "pull" the trans that last 3/8"-1/2", then something's in a bind and the trans should be pulled back a couple inches and reinstalled. Once the clutch splines and input shaft/pilot bearing are aligned, everything should slide right in place by hand. You should be able to manually push the trans up flush with the bellhousing.
