Well my 2002 type S has been giving me transmission issues. Last month I had the code P0740 and shuttering. I did the 3x3 atf change and cleaned the solenoid as some of you suggested on other threads. The transmission has improved greatly. My shutters are pretty much gone but this morning I had the same code pop up. I'm considering swapping in a J32a2 with trans seeing my car has 234k and it'll be kind of pointless to rebuild my tranny not knowing how much longer my motor will last. Has anyone done a complete j32a2 swap? If so what's needed. Will I need the jdm harness and ecu? Any info is greatly appreciated thanks

 

J32A2 is your existing engine.

 

I'm meant j25a I was considering swapping out my J32a for a j25a

 

you mean J35.

 

The Honda inspire j25 motor

 

oh, so you want to replace your 260hp motor for a 200hp motor.....?

 

and your J32 with 236,000 miles is still going strong...NO NEED TO REPLACE, REBUILD, OR DO ANY THING to it.

 

I bought this thing with 220k from some woman who barely did any maintenance on it. Who's know if the timing belt was ever done or anything else. If I can buy a complete j25a swap for $1,400 rather then rebuild a trans for $900+ why not then I can replicate an inspire. Horse power doesn't mean much to me. Better gas mileage lol. I bought it to last me through this winter but it could def turn into something more

 

idunno, your logic is off.

 

If I want to replicate an inspire what's the big deal?? I'm just weighing my options here... Not sure what I'm gonna do with it yet.

 

buy the inspire.. would be easier.

you're looking for options....the J25 isnt the best option available to you, that's the big deal.


you're better off running the current engine.
Change Oil and GO!


I just swapped in used J32 with 100k miles. I dont give a fuck if they didnt maintain it...I changed the oil and its running and will last me for more than 300k miles.

 

LOL this is a first one! a swap for a lower end motor???? Dafuq? I mean... why? Swaps are to improve if not the cost is not offset....

J31A1 to J32A2 (Swap a more powerful engine)
J32A2 to J32A2 (If engine dies, or lower current mileage)
J32A2 to J35A3 (Build a 3.5L Type-S Engine)

That is the logical procedure.... Not install a puny low powered engine instead... The J25 is a shit load less powerful than the stock TL-p engine.

 

I think the point that justnspace is trying to make is that these engines are pretty much as indestructible as a hunk of iron sitting in a bunker (unless the timing belt breaks).

The only reason to switch out a motor that makes sense would be to drop in an MDX 3.7L motor for lots more power. Otherwise, you're better off keeping the current one. If you're looking for improved gas mileage there are some things you can bolt on to it and you can replace your trans fluid with DW-1.

 

You guys are all entitled to your own opinion. That fact is that it's my car if I want to replicate an Inspire I can and if I do you'd probably be the first couple of guys to compliment me on it. I found a complete RHD clip for $2800 the guy is willing to sell the motor sperate. I'm not trying to turn this into a serious project. I bought this TL for $1,600 just to ride out through the winter. Now that the Trans if giving me some issues its gotten the ball rolling on a few ideas. I'm not a moron I've built cars in the past mainly civics and tegs but this is my first TL and wanted some opinions. Not a swaps are for upgraded hp sometimes there for replication purposes.

 

at not trying to do serious project but what you are proposing IS A SERIOUS project.


Look man, you're the first to do this proposed engine swap. DO IT! then shut all the haters up!


again, your logic doesnt make sense on what you want to do, but like you said, to each his own


so, swap it, man. do it.

 

you came here for opinions and options, yet when we present to you different opinions and options, YOU SHUT THEM DOWN!

so, go ahead and do the swap, man.

 

If you read my post I was looking for info on a j25 swap ( I incorrectly wrote j35 ). I wanted to know what else was needed. You offered your opinion and kind of bash the thought of putting a j25 in my TL. Lol as for the serious project i meant doing a RHD conversion. Rippin out my 3.2 and sitting another j in it will take me a day. All I wanted was some help not a bunch of dicks talking shit about droppin a j25 in my car.

 

^because no one has done it.


How can we give advice if NO ONE HAS DONE IT?

 

How much would it cost you to import an Inspire?

 

+1 Crab Man aka Justnspace...
How can we give any advise if NO ONE has done such swap, Also you are dealing with a Type-S which has more electric gizmos than the Inspire which is more like a TL-p... The TL-S has more things to consider.

 

so your trans is shot and you want to spend the money on a J25 motor/trans to put in to make it more JDM, BUT you dont want to waste the money on a trans rebuild?? How about spend the money(1/3 the price) on a AV6 trans and call it a day.

 

What I'm afraid of is paying over $900 to rebuild this trans and my motor blows. These guys are saying my motor is indestructible but I personally haven't seen a car make it this far. My thought process was if I'm going to just shell out a few hundred more ( to replace the entire swap with lower miles ) I minus well make it a bit more unique instead of the same swap. This AV6 trans is a cheaper route? I haven't really looked into it yet.

 

^ I have 218K on my original Engine... I plan on AT LEAST making it to 400K before even start to wonder If I might need a rebuild. Honda Engines are bulletproof if you take good care of them..

Longest Honda Engine I Know? A MILLION MILE K24... Just search for "Honda Million Mile High Club".

 

the engine wont blow, as long as you maintain it and bring it back to life. so this means changing all the fluids. even the coolant.

new fluids will help clean the engine.
worried? change the fluids again.

timing belt and water pump need to be changed every 105k miles.

there are only a few ways to "blow" an engine.

- overheat the sun of a gun and you'll have a broken engine.
- if timing belt snaps, you'll have a broken engine.
- if 6 speed manual and an over-rev condition happens, you'll have a broken engine.
- suck up some water through an aftermarket cold air intake, you'll have a broken engine.

 

like mentioned earlier; i bought a used 100k mile(actually not even sure the mileage, i know its 100k or over.) engine for $650.

had a mechanic swap my blown motor(six speed over-rev condition) for $650 and my car is running like a motherfucking champ!

 

Like he said....If you have a factory type-s, your car engine is a J32A2. So your new transmission & engine would be plug and play.

 

J25 is a 99 TL setup with the 4 speed, good luck with that.
If you're trying to replicate it just throw the 2.5 engine covers on it and you might fool someone.

 

The J32a2 motor i pulled out (only pulled it out to do a 3.7 conversion) had over 400k miles on it, ran 15-20k oil change intervals and didnt burn a drop of oil. If your motor is in good shape and you maintain it it will outlast your desire to keep the car.

 

If you really want to pull the engine, I would find yourself an AV6 tranny, pull your engine to do the swap and while you're at it do timing belt and crankshaft seals on both ends.

 

my j35 swap will be around the same price... why downgrade?

 

My j37 build was less money than this J25 would be. Throw in a used AV6 trans and call it a day. I see no point in trying to JDM a car made in america, especially with it being a down grade.

 

If I'm not mistaken that code is for 3RD OR 4TH gear pressure switch! Easy to replace if you can get your car raised up!

 

P0740 is actually "Lock-up control system"

FWIW, troubleshooting steps in service manual include:

- Resolve all other DTCs first before diagnosing
- Measure line pressure (if not within service limits "rebuild hydraulic system")
- Replace torque converter clutch solenoid valve
- Replace A/T clutch pressure control solenoid valve C
- Reset PCM (remove "BACK UP" fuse/passenger side under dash fuse/relay box)
- Recalibrate idle, drive at 55 for more than one minute
- If P0740 comes back, replace transmission and torque converter

Since dirty fluid can cause so many problems with these trannies I think a drain/fill should be done before anything, as the OP did.

 

Sorry for bringing this topic back from the dead, but I couldn't just pass by quietly. There is no point in swapping a J25A, as a person who used to have this motor It's less reliable than the J32A2, the gas mileage is actually worse (I did the reverse swap about a year ago, J25A1 -> J32A2, and the J32A2 actually got better gas mileage, and that's with a few bolt-ons too). Not to mention the obvious power deficit. Although I have to say, it isn't that big of a slouch, it actually pulls ok-ish for a 2.5 liter V6.

 

I am guessing that if Reverse or the 2-3 upshift is too hard, then that means there is too much pressure...?

This has got to be one of the dumbest swap projects I've ever heard of.

 

by the way, on a 2005 acura TL, the Helm shows A is on the front and B is on the rear.
And on my car Black is in front and brown is in the rear.
So I am not sure what is reversed. The PDF or HELM
THe PDF says it is for 1996+

 

AHH.. SONNEX has a ** comment.. They say they might be incorrect. Don't want to go by their picture.. Not for a 2005 anyway. Each model may vary. hahhaha

 

I want to thank everyone who posted their experiences before me, and to the pioneer who first attempted this swap. Here's a few things I encountered during my swap.
2000 Acura TL (250,000 miles), obtained trans. from an '06 Accord (BAYA trans) with 118,000 miles on it.
The lower (2) mounts did not line up with my subframe, were way off. Used the old TL mounts.
Swapped every sensor and bracket. Used TL warmer. Used TL Range Switch, did not mark relation to trans, so i put the shifter in neutral, the switch in neutral, and the linkage in neutral. Worked perfect, no adjustments needed.
Used a bottle-jack and a 5"x5" piece of plywood to support motor during the swap. Worked fine.
Used floor jack with a 14"x10" piece of plywood bolted to it as trans-jack. HIGHLY RECOMMEND STRAPPING TRANS TO BOTTOM OF WOOD OR TELESCOPING PART OF FLOORJACK. Went sideways with the install, in between the drivers hub and bumper.
Used torque converter that came with the Accord trans, filled it with Honda ATF first.
On the Power Steering assist i just bypassed it like the write up says, looping it back to Rack and Pinion, and used 2 small hose clamps tightened down good and have no leaks.
The junkyard Accord trans works awesome! My car has not shifted like this since it was new (original owner) and I could not be happier.
Honestly, the hardest thing with this whole job was getting the lower ball-joints tight again after it was all done.
Junkyard trans was $500, with another $75 or so for fluids and a 36MM socket for the axle nuts.
No leaks, no check engine. Everything works, even tiptronic shifting and tcs.
Thanks again to everyone involved with this thread!

 

You didn't replace any hoses, seals or mounts while you were in there? Glad to hear about your great experience nonetheless. :-)
