Difference Between AT Engine and MT Engine?
So I have fried the valve train on my CLS6 and now in the market for a engine! I'm going to buy another J32a2. Question is there a difference between the auto and the 6spd engine? Need to know before a buy! Thanks Acurazine!!!

aren't you effectively doing the inverse of whatever the AT owners do.. (aka 6speed swap)..
if it works for them, what makes you think it won't work for you

You have to swap some things from your 6speed to the auto engine.

This thread is for a J35 and shows what parts need to be swapped. You should get a J35A3 just like the OP in that thread.

Holy shit,
NO it's NOT the same engine.
You have to swap a bunch of stuff. If you can't find a manual engine, you'll have to buy all the parts to convert it to a manual engine.
I recently swapped from manual to auto, so I can sell you all the manual engine parts if you need. Let me know.

You will need to swap front cam gears and sensors, crank position sensor and gear. You can easily buy an auto engine and take the few things off your engine and swap them over.

My Honda/Acura mechanic told me that although they matched the 6MT to have same amount of HP as the AT model (for sale purposes), it is a different motor from the AT. Lots of things are different on it, I forgot all the details he told me about but yes, they are different.

When you get the new engine drop the oil pan. Swap out the front cover/oil pump assembly. The crank sensors are different and mount to the cover differently. The other thing is you must remove the cam gear from the front head and swap the plate with the cam sensors. To do this you will have to do a bit of grinding to the outside of the head itself. All in all if you have the ability to swap an engine then these things are not a big deal. Oh and the harness is different so you'll have to swap that as well.

Are people so quick to respond and contribute that they have no concern as to the validity of the information being reported?

As have I. J32A2 out of a CL-S auto into my CL-S6. I know what I had to swap... If you don't like my info prove it wrong. This is my DD and the engine has been in the car for over a year now. Obviously it's right. And nobody asked about the J35A3 so I don't know what you're getting at with that info.

Posts like this annoy me. Multiple people above you have stated that the changes are minimal or even gone so far as to state exactly what those changes are. Your admittedly uninformed opinion on the matter does no one any good.Again, misinformation helps no one. When he questioned this information, you even stuck to it. The guy who questioned you has actually done the swap (J35A3 if we're being particular on the details).

So sorry to have annoyed you, you must be a very pleasant person to carry a conversation with. I can tell you really respect opinion of others. BTW, the mechanic I mention owns a specialized Honda and Acura shop, known all over Midwest, people drive way out of their way to see him, 26 years doing this. He can tear down a J motor and put it back together in his sleep. Certified in everything Honda certifies in. What are your qualifications?
I had the capability to read the information in the posts above the one you made before sharing my own thoughts.
The fact that I work in heavy civil construction and I still seem to know more about J-series engines than this mechanic would presume to.
If your mechanic is as qualified as you say, I'm sure he knows what the actual differences are. However, when the information is given in detail directly above you in response to the original person asking the question and you tack on an opinion that offers a generalized, "they're different", how do you expect that to not be conflicting with the correct information? If one of my 6-speed engines were to blow, I could go buy an automatic J32A2, swap over my wiring harness and all sensors, and I'd be back in business. Given that's what the OP was intent on doing, your answer would lead him to believe he couldn't.

That I have first-hand knowledge of J-series engines coming from my own research and owning many different ones.

I would have hoped that you could tell from those responses that I was being intentionally ridiculous. I worded it that way to demonstrate how all the qualifications in the world don't mean dick if you spread misinformation.
But now you seem more concerned with my attitude than with the accuracy of the information. I'm the opposite of a narcissist. I have already explained why I took issue with your information.

Keep listening to your mechanic, certified or not he can still feed you BS. As long as your happy.
As for buddy grinding the outside of the front cylinder head to get the backplate/sensor to work..
What do I know..

You could list the number of parts that are different. Just look at a parts diagram for both engines. I've personally converted both ways and ran the engine in both configurations.

What? You're mechanic is an idiot, they didn't design a completely new motor just for the manual CL.
