Question for the experts:

I have a wrecked 06 TL (auto) and a 03 TL-S (auto) with a failing engine. What, if anything, needs to be modified to drop the engine from the 06 into the 03.

 

The J engine is bulletproof with regular maintenance. Why is yours failing?

I recommend getting an engine from an 02-03 type s. As it will be plug and play. Or rebuild your failing one.

 

Hey. Thanks for the reply, but I think you missed the point of the question.

My failing engine has 250K miles on it. It's done it's duty, and deserves a rest. The fact is that I have a good engine and transmission sitting in the driveway that I don't have to buy. I am looking to find out if there are any significant differences between the harnesses of the 03 and 06 J32s. Do you have any experience with that? Thanks.

 

Have you asked this in the 2G forums? Unless a 3G person came out of a 2G, it is less likely many here will know details of the 2G.

 

no not him specifically,

but it has been asked ad nauseam multiple times in both forums..

 

Yes.

I didn't want to spam the question, but I went ahead and asked it there when I didn't get much response here.

I did search for it before posting, but didn't find anything relevant.

 

when you say failing, be specific, eating oil? low compression, misfire, etc...
