I have an Ls hydro tranny for sale. The only issue is a grind when shifting into 3rd at higher rpms. If you drive around and shift normal it's fine. I've been driving on it for a year. Mileage is right at 100,00 now. I'm swapping out to a gsr tranny since I'm boosting now. Item is located in Frostburg,Md 21532
Pickup only. My asking price is $250 OBO

 

ls trans better for boost ....

 

agreed you want those long ls hears for boosting specially for some fun highway pulls!but glws

 

You guys might really wanna learn what you're talking about first before you start talking. Gotta love H-T kids though.


The LS tranny is the longest of all b-series trannys and has the weakest synchro's and weakest differential.

The GSR tranny has a stronger differential and optimal gearing.

Please please do some research. Here is a good article so maybe you'll understand.

Gear ratios are merely a way to trade torque for rpm. With a higher numerical gear ratio, you are putting more rpm at the wheel. With closer gear ratios, you are able to stay at a higher rpm in between shift points. Something like the LS transmissions are suited more towards the broad torque curve/low reving LS engine. It keeps you in the peak torque area in between shifts. The ITR/SI/GSR transmissions keep the rpm's built up in between shifts, to stay in the more peaky powerband.

Having said that, for the track the itr/si tranny is the best hands down. Most high whp turbo engines are operating between 5.5-9k, and having their shift points in between. In combination with a tall slick size (24.5"+), and the high shift point (8.5-9k), you are able to keep the engine operating within the optimum torque curve.

With the LS transmission, between shifts it would possibly drop you out of the optimal powerband and therefore make you slower. Gearing simply put allows you to stay in the powerband of your engine in between shifts.

The myth that you stay in gear longer with the LS transmission makes you faster is purely false. Think about that statement for a second. Acceleration is the measure of velocity over a unit time. Watching the rpms climb on the tach during a 3rd/4th gear pull, they would be climbing slower than with the si/itr tranny. Looking at the definition of acceleration as a measure of velocity over a unit time, the engine would be getting to the same velocity over a slower time lapse. This would yield slower acceleration, and simply put make you slower.

Having said that, the gsr transmission is probably the best balance of a street/strip transmission. The gearing is a little less aggressive as the itr/si transmissions, which will yield a little more traction. For all out acceleration si/itr tranny wins hands down. For a slower car, go with the LS transmission.

 

GSR>LS for boost both off personal experience and theory 99% of the people who say an LS trans is better for boost have no clue what they're talking about nor any personal experience, they're just repeating what they heard

 

^^^ Finally not everyone on H-T is retarded. Thanks for confirming what I've been trying to explain.

 

i would never want a ls trans unless it was for DD. you dont want to be out of the powerband like a ls trans will do.

 

Yeah that's why I'm swapping them out. Especially now that I'm going for more power. If this tranny doesn't sell I'll just use the LS 5th and final drive in the GSR and have the best tranny ever. Low highway rpms and can still trap 140mph if need be.

 

exactly. with a ls trans you would probably not even go to 4th. and u would lose a lot of mph

 

hey bet option use ur gsr transmission way stronger i switch out the 5th gear in mine i use les 5the gear u need bothe gear one on main shaft and other shaft bolts right on no mods need its nice have a highway ger to cruise with we love it im looking for a 5th gear set now to do another one of my transmssions

bu gsr is way stronger thanks newbies for ur input lol

 

I can't even understand what you're trying to say.

 

Just interested, at how high of rpm does the 3rd gear grind start to occur?

Oh, and thanks for posting that article. I had no clue about the gearing differences....made alot of sense.

 

It was typical around like the 6-6,500 mark. It's just a 3rd gear syncro but I felt no need to replace it since I wanted a different tranny anyways.

 

GSR transmission is a MUST in my book for any B-Series.

You'll love it. It was cool meeting ya and thanks for the smooth transaction!

your the only one who has kept your word and showed up to buy the part with out flaking and wasting my time!

 

Well I was just informed by my friend who worked for a transmission shop and now Thomas Subaru/Honda. That the input shaft bearing is destroyed. So now I have to pay him to take it apart and replace the bearing. That's also if nothing else is screwed up. You can hear the loose bearings ticking around when you spin the input shaft.

 

2NR0066 just called me. He basically informed me that I'm beat and he will do nothing to fix it. He's saying that any tranny you buy will have something wrong with it. He's saying that how does he know I'm not just trying to get money back on my purchase so I offered to drive 2hrs both ways and return the tranny. He's offering no help except sorry about your luck. As it stands I'm saying he is a bad seller. Especially since he swore to me it was in great shape with less then 20k "almost impossible imo" no grinds or pop outs.

 

dammmm a sacmmer thats wack go to his house throw it threw his window !!!

 

You can't use an LS final drive on a GSR diff... the GSR diff has a different bolt pattern. You can just swap the main and counter shafts 5th to the LS for highway use. I have a B16 tranny with an LS 5th and its perfect for my all motor LS/Vtec dd. GSR tranny is the best OEM tranny for boost...

 

Sucks he lied but you should've checked it before you got it... Input shaft bearing isn't hard to replace you should do it yourself. There are numerous threads to help out while you do it. Good luck with sale

 

So is it worth doing in a gsr tranny really? I know it brings the rpms down when cruising in 5th but is it that big of a difference?



It didn't cross my mind. Yeah I know they are not bad. I have a a friend who works on trannys so I'll just have him do it and toss him a few bucks.

 

It makes a huge difference for me since I have a Buddy Club Spec 2 exhaust. At 5k rpms with each 5th gear... B16 was 95mph, GSR was 103mph, and LS was 112. My vtec hits at 5,200rpms thats why I checked the speeds at 5k. LS 5th saved me from selling my exhaust lol. And I gained 5 mpg on the highway from the straight B16.

 

My exhaust isn't that loud so that part doesn't bother me. I'm more meaning at 80mph what is the rpm difference between gsr and ls. I think gsr is 4g @ 80mph
