I am in the middle of swapping the starboard engine (Chrysler 318) on my 1972 28' pacemaker. I had hired a mechanic to do the work, but I wanted to get things finished asap, so I took care of disconnecting everything and have started to change over some parts (He pulled the engine). The only piece that I have left is the transmission. Just want to be certain that I am not misssing anything. It looks like there are 6 bolts that connects the tranny to the engine (which have all been loosened). Am I missing anything?

Dont forget to grab the flex plate and flywheel when you pull the tranny off of the old engine. Even if you got them from Leo's old boat, they are good to have as spares

Will do, thanks. Is there anything else I should be looking to disconnect? I want to be certain before I start cursing and pulling. Wouldn't be the first time I wasted hours banging my head against the wall only to realize I forgot to discoonect something.

my trannys bolt to the bell housing, which is bolted to the block with the starter mounted on top of the bell housing. There is a metal plate, which also bolts to the bell housing behind the flywheel (towards the front of the engine) which covers the bottom part of the flywheel and keeps it from getting messed up from anything in the bilge. The tranny has 2 oil cooler lines, the shift cable and the 2 purple wires for the tranny alarms. When you unhook the 2 wires, starter, and shift linkage, the only things left are the 2 mounts and the 4 bolts on the shaft flange. The tranny should slide back off of the flex plate which is bolted to the flywheel (at least on my GM engines).
I had a heck of a time getting the 2 bolts out which mount the tranny mounts to the tranny. There wasnt a lot of room to get in there with a wrench. I ended up backing out the lag screws that goes through the mounts into the stringer and then bolting the mounts onto the tranny while it was in the air on the lift. I put the tranny and engine into the boat in one piece since it was a lot easier than trying to bolt the back cover on with the engine sitting in place

Terry,

Thanks. It sounds like I have everything. Fortunately the engine and tranny are laying on blocks. It makes it a lot easier to remove the bolts. Some of them were rusted, don't think I would have been able to get them loose inside the boat.

Shawn, you need to over to the auto store and buy a can of PB Blaster, it's a bolt and nut loosener and the best stuff I've ever used, it'll help you a lot....Leo

Shawn,



I changed all my parts, including the trans, to my new engine this past Sunday. I find it easier to unbolt the flexplate from the flywheel with the trans in place and remove the trans and flexplate together. Access is easy through top inspection/access hole on the upper part of the trans. Mine has a rubber cover. Use the crankshaft pulley bolt to rotate the engine to access each bolt. I installed it with the flexplate on the trans input shaft using never seeze. After I aligned the bellhousing/trans pins I installed a couple of bolts from the trans to the bellhousing, rotated the engine to align the flywheel/flexplate bolts. As for the trans mount bolts, I removed mine from the stringer. Instead of lag bolts, my engine and trans bolts were 1/2" bolt and nutted. Of course they were all rusted. After some PB Blaster and a good 1/2" impact wrench the engine mounts came loose. The trans bolts were frozen in the rubber mounts. Good thing for me the bolts were grade 5 and I was able to snap them with the impact gun and remove the bolts from the mounts and stringers later after a good soaking. As I install the assembly on Sunday, I am using Grade 8 bolts and plenty of never seeze. Good luck, John

The transmission was changed over. 6 bolts piece of cake. Thanks for all the help.
