The 4AT....
....I feel like this transmission gets a bad name for no reason. Has anyone ever noticed how much the charachter of this transmission changes via the ecu when it learns an aggresive driving style? I swear sometimes I feel like this transmission knows what Im gonna do before I do. Other times of course I scream DOWNSHIFT! at the top of my lungs

I have also noticed this. I thought, just because for no real reason, it was only the 5.5 gen that adapted this aggressively. It's fairly awesome. I think the reason most people diss on it, including myself is because Nissan should have implemented a 5AT for this gen or at least the latter half of this gen for both performance reasons and MPG.

Never kept the 4AT stock enough to do a A-B comparison but with the HD2 the car's very responsive.
Suicidal much

Lol. It's there. I think it's supposed to come in somewhere between 110-120mph. Over the years I've had it work and other times it goes right through it and doesn't cut fuel. Pretty weird. I read you can put a switch on the blue/white wire on your ecu harness....switch it off...Lol. Not sure about those colors though....don't go snippin without checkin twice!

Old subject, but the 4AT's are said to ahve a soft limter in the 128-131 range, 6MT's and I assume 5MT's do not have one IIRC.
Mine has seen 137 on a dyno, but again, I have TS F-Spec ECU. The limiter here was the rev limiter in 3rd (7100). SR20DEN took his in the mid 150's in his 6MT.

I agree with you guys somewhat. At the same time, the tranny definitely needs that extra gear. Besides that, those that have ran their 4at against MT cars will know how big the disadvantage is, just due to no extra gear and MT's with similar power will always inch ahead (unless driver sucks).
And I say that regardless whether you have a shift kit or not, I have one and every MT car with similar mods/power always inches ahead slowly (esp. 4th gens with less weight). Now, I can say that my 4AT with transgo does move forward pretty violently from a dig and has beat most of said MT cars from a dig up to about 60mph.
Up to 60-70mph, it's beastly and pulls like mad, after that it starts to fall back because 3rd and 4th go on FOREVER.
As for top speed, I've seen ~140's in my 2000 SE.

Either way, this convo has digressed terribly.

Mine has no limiter, its only drag limited. And from research it seems my speedo reads low by approx. 3-5mph depending on speed.

The speed limiter is about 145 mph, but I did hit my rev-limiter a couple of times at 130 mph in 3rd gear! I love having an A/T 5.5th Gen and how aggresive it is...but I too wish it was offered with a 5AT with manual-matic mode for more control and quicker shifts than the best 6MT owner could ever accomplish ...As I get further in age I love having an A/T especially in Houston traffic....

My biggest gripe with the 4AT is the short shift out of 1st.
I hate how it always shifts mid turn if left in drive, unless you give it 50% throttle or more. Transgo kit made it better and revs build faster so this happens less often to me now, but at the same time that shift mid turn is quite scary at times (with hd2 kit) when you're getting launched to the side.

Btw my car has 103k not 203k....trans kit was done at around 90k on a perfectly maintained tranny.
I'd say its well worth it, miles dont matter. Its all about what kind of shape the tranny is in.
Money wise, I've put thousands into my 5th gen. But, I have new everything. Suspension, brakes, lighting, trans kit, full exhaust, etc, etc...

I got my PUR bushings from the guy that sold them on here a while back, I forgot his SN (doesn't do much for you but yeah). They are gutted MT units filled with PUR. Like 90$ I believe. Easy to install. The torque link is what, 130$?
Problem is I don't think he does that anymore, but there is a write-up below. A little more elbow grease, but I think it's worth it with a VB mod, actually, you shouldn't have one (shift kit) with out them(poly mounts).
There's always the ES option also. Slightly more $$, and you need a press, or to have them pressed in.
FYI, mounts are the same for 95-03.

Good info, thanks man! I will absolutely do that plus torque link.

Maybe my phrasing looked like it was doubting your purchase..Lol. My car is the one with 203k. I'd say my transmission is in good shape. I'm guessing in another 50-100k miles it would need new clutch plates/rebuild. When it's not fully warmed up in winter time it shifts a little more "slidey" so to speak. It's got a couple more good years at least I think.

^^ Confusion cleared up.
Thanks for all that info, thats awesome. Gonna look into it now, I was planning on doing ES and buddy of mine can help to press them in. But if I can find a cheaper route like you mentioned, definitely gonna look into it.
