Ok so about a couple of weeks ago I blew my 2nd gear syncros and 3rd gear gears...(don't ask how) and I bought a g85 tranny with LSD...I have 800 miles on it and works perfect!! Different final gear... I can't wait till I get my big turbo on and see how this monster does!!!!

 

Awesome

 

y lsj trans on a lnf. i mean i see y do lnf tranny on lsj but not lsj trans on a lnf lol

 

I was always curious about this. I thought the transmission between the two were the same.

 

nope lnf ones has a bit of longer gears i think it is

 

Oscar (09whiteSSppsssshh) just did the samething, he likes it better with the LSJ trans from what he was saying.

 

I thought the axles were different sizes.

 

The CV shafts are much beefier on the LNF but they bolt up directly to the lSJ trans so I am willing to bet the OP is using his CV shafts with the LSJ trans. If I ever blow my trans I would put an LSJ trans in my car. I would rather have the shorter FD ratio.

 

the transmission splines are the same. its the hub that is different

 

Good to know maybe i will shop for a LSJ trans

LNF clutch and slave work just fine?

 

I thought the case was beefed up on the LNF trans? Third gear still goes ziiiiing!

 

If the trans are the same why would the clutch be different? I mean I have a lnf TOB in my trans.

 

Can anyone list the part number for the LNF and LSJ trans with the G85 option

 

I asked zzp about the 4.05 and 4.45 gear and they said it's better because you are not in third gear as long, so you don't put as much stress on third gear.

 

Interesting for sure

Good to know it bolts right up

Anyone selling a G85 LSJ Trans?

 

same basic trans, same model. LNF has a stronger case and 3.82 final drive
just swapped 2 over the weekend. LNF 4.45 setup into a turbo swapped LSJ gt3076r (awesome gearing now).
and an 4.45 rebuilt lsj trans into an 09 lnf w/ a gt3076r that car is yet to be finished since it was converted to auto, and now back to manual.
.

 

The LNF clutch is the same as the GMPP clutch for the LSJs.

 

not exactly the same. its similar

 

It is from what I have heard, but I bet LSJ trans is a whole heck of a lot cheaper and easier to come by.

 

LOL for real now that I know I can just pop one of these in it.

 

I definitely would go LSJ if mine blew, I'm not waiting 3 months to have my car fixed by GM under warranty.
Anyone know offhand how well a LSJ trans will hold up cryo treated? Might be something to do if I happen upon a cheap LSJ tranny for a back up for when mine blows (not if, but when)?

 

My bad I heard someone say it was the same part no.

 

ill have to see how it holds up with the big turbo set-up... anyways does anyone know where to buy parts for that tranny? to beef it up a little?

 

more gear is always better... they gave us a retarded gear set to begin with so i want to bang that limiter in 3rd thru the traps lol

 

Why did you make another thread?

You won't find parts to beef it up with, and very few places will work on it anyway.

Contact Powell motorsports, best bet.
