Is a lsd transmission a direct bolt on for a lnf
 

As long as its an F35 trans from Cobalt it should bolt right up. The 4.05 ratio in the supercharged cars is the preferable one, it will take more abuse. Dont forget new flywheel bolts as they are torque to yield and also a new throw out bearing and clutch pipe.

Is it your daily driver even in winter, or a summer only car? LSD makes a big difference come winter.

I would get the trans with the lsd, regardless of the ratio.

Also interested in this this thread as I'm wondering the specifis regarding putting an lsj f35 in an Lnf .... Like what clutch to use an etc! There was something that had different amount of bolts used etc. ???

You can put a 4.05 lsj trans in a lnf that came stock with a 3.82 setup. Clutches also interchange. The only issue is some lsj flywheels aren't bored exactly the same as a lnf. As long as you get a lnf flywheel everything will swap just fine. Personally if you aren't high hp the upgraded lsj clutch kit it a good kit also called gmpp. A stock lnf clutch setup is also very close and a good inexpensive clutch.

​​​​​​So basically I'll need:
​​​​​​- Lnf flywheel. I assume I'll need a new one when replacing the clutch.
- lnf TOB
- Bully stage 1 clutch for lnf.
AND THATS IT FOR SWAPPING??

also why does this site always auto-incorrect ????

flywheel bolts, clutch pipe.

You have to use a new flywheel, the tolerance for resurfacing is nothing.

Okay thanks. lnf bolts and clutch pipe? And lnf flywheel is best or bully flywheel?

Where can I find these parts and part numbers for all the parts needed??

What is a bully flywheel? Never heard of one. Just get an lnf flywheel off of ZZP. Or a luk flywheel from rock auto I believe. Make sure the kit you get includes pressure plate bolts and an alignment tool really helps also. Think the gmpp kit includes it if you decide to go away from the "bully" setup. Which again I've never heard of.

Well I'm sure GMPP is good .... And if it includes most of the stuff I need for a decent piece than that may be the way to go .... Is it for the lsj or lnf??

My friend has a bully on his 07 ion 2.4 and it's great.

Far right column is the part number for the flywheel.

K so .... What's the difference between part 55560938 (G85 4.05) and 55563239 (ditto) ....
apparently the latter part number replaces the former part number but it's the same thing.
Is there any differences?

Bump

Couldn't tell you, never purchased one from a company, only from a fellow cobalt owner. Where are you getting it from?

I've bought the older version .... Just wonder if there's anything different. Regarding using it on my Lnf. Why was the part number changed if it's the same etc ??? ....
Basically the older version plate has no 4.05 printed on it.
Says LSD and part number though.

Gear ratio should be in the gray area. Need to make sure it's from a cobalt as some of the early redline trans won't work. Use the search on here as I think there are some interchangeability topics. Something about the reluctor wheel not working with the speedometer setup in the cobalt.

the 2004 ion redline did not have a vehicle speed sensor in the transmission, it was mounted on the steady bearing and the passenger side jack shaft had a reluctor on it that it. the 04 ion redline trans will not work in any 05+ cars. and no, running the 04 ion redline jackshaft assembly doesnt work, the reluctor wheel is a very different tooth count.

Thanks I'll try and clean the plate a but more .... As well as the rest of the gross area.

It's from a G85 spec LSJ that was a numbered car and unfortunately got written off. It was an amazing blue color.
Thankfully I don't have to worry about it being from the slightly odd early redlines.
