Hey everyone. I recently got an 07 acura tl-s auto from the auction with 70k-ish miles and have been looking for one with a manual and finally found one but it has way more miles. Ik that some people will say to do your research but i couldn't find anything on this topic. Maybe I was searching the wrong stuff but im curious if there is a difference between the j35a8 auto engine compared to the j35a8 manual engine. Like any sensors that are different, will the harness plug right into the engine with less miles that came from an auto, mounts or if the tranny will even plug right into the engine without any sort of modification. Any Insight will be appreciated!

 

I vaguely recall it is different to the point a direct swap is impossible. Even the subframe on each car is different.

 

??

If you can another type-s car. the swap is direct. you will just have to swap the engine harness, and underdash harness, ecu along with the engine,tranny, subframe, mounts, gauge cluster, add clutch pedal, swap shifters.

Its a direct swap.

 

Not with OP's current get up is my point

 

well won't it be direct since they are both type s? Just have to go through the hassle of swapping everything. Only reason im thinking of swapping the drivetrain is because the damage on type s with the manual is too and the the auto type s is pretty minor

 

At minimum expect to change the front cam gear, backing plate, crankshaft lower front timing gear, ckp and cmp sensors. All easy stuff with both motors out and timing belt removed. Do the timing belt, tensioner, and check adjust valve clearance while you're at it. Mind you this is not considering changes to the engine/trans harness and ecu, pedals, shifter etc already mentioned. GL.

 

I get But why

 

My guess is these will be needed to make the automatic transmission engine manual transmission compatible.
It's more or less the same swap components needed to make a 2G CL / TL automatic J32A2 or 01-02 MDX J35A3 manual transmission compatible to work with the CL-S6-speed ECU?

 

Wouldn’t a J35a8 auto and J35a8 manual need no changes on the engine?

 

“change the front cam gear, backing plate, crankshaft lower front timing gear, ckp and cmp sensors.”

I stand corrected. These were the ones I set aside from an 05 RL J35A8, Same p/n for 3G TLS MT.

Apologies for the misinformation.

 

And yes, these are the parts for 2G 6MT. Interestingly enough the TDC sensor is the same between 2G 6MT and 3G MT/AT.

 

Oh, that’s what you meant about ‘back plate’. Yes One of the 2G cam gear back plates has two timing sensors while the 3G only has one. The cam gears are also wider on the 2g, so if you putting 2G heads on a 3G block, you will need to swap the cam plates and cam gears, as well as tap a new hole for the sensor bolt.

And seal/weld the oil return drain on both 2g heads to fir on the the 3G block.

 

@619rcr how is your 6mt swap going bro?
