I have two Tauruses, an 03 and an 05, both with 3.0 Vulcans. The transmission in the 03 went out a couple of weeks ago. I found out that it's a common occurrence for the splines to shear and that the rebuild is very expensive. The car has 250K miles and the front end has a lot of slack in it so I don't think I'll dump too much money in it. The 05 engine with about 125K dumped all the water out of the coolant system into the oil pan. I looked at the gaskets and didn't find any indications of leaks anywhere then looked at the heads but didn't see any indications of cracks. I decided that I wasn't going to put any money into that block since I couldn't find any leaks up top. So my question is, will the engine from the 03 fit the bell housing on the transaxle from the 05. If they will mesh up I can put some time and money into the 03 engine so I will at least have one working Taurus. I plan on pulling both engines when it cools down a bit. It's still too hot down here in south central Louisiana to want to work on them when it's not absolutely necessary for the moment.
Thanks in advance for any advice.
