So I been searching around for answers and nothing. So my question is I have a non lsd 3.82 trans I would like add LSD to my trans but I would like to know what is needed and who is willing to do the job because it seems like no trans shop around me work on them. Also what if I would like a 4.05 or 4.45 final gear what would I need to find and which one is better and stronger.

just curious what cars did the LSD trans with 4.05 & 4.45 come on just in case i bump into one thank so much

 

you are going to need to know a tad more about what your stock f35 came out of

https://en.wikipedia.org/wiki/F35_transmission

There are some smart ppl on here, but the forum looks to be slow user wise. ZZP or Powell would be a good resource to ask as well.

Installing a LSD aftermarket is a pita....doable but a pita. So many say you are better off buying a used trans with all the parts you already want.

 

trans came out of a 08 SS/TC non LSD I sent a couple of emails already to Powell no response yet and my understanding is zzp does not deal with trans no more. So that's is why I was asking on what cars did those trans come on because I read that Wikipedia has wrong info on that subject

 

Powell or Lnfwagonss on here. The 4.45 gears never came in an F35, but gears will swap in. I believe they came from some kind of anemic Saturn to help acceleration. Mongorat427 may have a set, but they are getting very rare

 

the 4.05 should be standard in that LNF f35, right?

 

Nope, 4.05 came with the LSJ engine SS, the 3.82 came with the LNF engine SS

 

Yes, but you may be able to find an LSD LSJ F35, which already has the 4.05's and save a ton of money, then save your existing trans for an emergency spare, or sell it

 

So my best best is to find a LSJ with an LSD and they came standard with a 4.05 instead of trying to add LSD to mine.

now I'm assuming that the LSJ trans it's a direct fit to a lnf

 

does the LSJ still have the same rpo code g85

 

Yes and iirc the some of the 4.05 (if not all) have LSD printed on the ID tag on the transmission.

 

HHR SS LNF (manual) came with 4.05 LSD or non LSD

 

if you do some research there is a lot more transmission shops than you think that will work on these trans. Since they came in Saabs there are transmissions shops that have the tools and can work on these transmissions

 

I thought the HHR had a 4.17 manual trans or is that just the non SS models

 

thats the non ss hhr with either the 2.2l or 2.4l. that was the f23 transaxle, not the f35

 

What everyone said- lsj and 4.05 is the better way to go as it can take more torque off the trans with the 4.05 gears over the 3.82. I run a 4.45 currently but am going to send lnfwagonSS my original 3.82 trans and have him build it with 4.05 gears. Then save back my 4.45 trans as a spare. The 4.45 gears are scarce and are expensive- about $400 a set and they can’t be purchased new. They came in Saturn vehicles and not many of them. They are the highest rated for strength on a trans but only because they take some of the load off the internals. There are a few guys on Facebook that can build decent trans, but lnf wagonSS seems to be the best, and can offer more selection, but he isn’t cheap, and there is already a line forming for his work. Mine was built by Kelley gibson and it’s ran good so far but I don’t know if Kelley does them anymore.

 

So let's say I want to send trans to lnfwagonss so swap from 3.82 to 4.05 would I only need what's in the picture

also to make it LSD I would only buy a Lsd diff correct how much more or less do you thing they will charge to do the work on the trans

 

We cant give you a price because LNFwagonSS offers so many different options. You can go from a basic build to a complex and indestructible trans. Jason offers internal structure bracing, treated gears, upgraded hardware. He is the man when it comes to building F35 trans.

 

do I just pm Lnfwagonss or is there a better way to get a hold of him and I'm guessing his name is Jason

 

B3Design on facebook

 

thanks I don't have Facebook but I'll get a hold of him somehow looks like he does good work I wish he had a website

 

When you get the 4.05 done, sell the 4.45. You wont need a spare.
Yes. keep the bearing though. Only OE quality Timken bearings are imported for these builds.

Some of the best deals are on direct media.

 

Do you already have a stock Torsen-style helical diff or would you be removing it from your current trans and installing into the non-LSD trans? The install shouldn't be too difficult as the most challenging thing is normally setting up the correct preload on the bearings/diff. It's also a good idea to use new hardware/fasteners.

As suggested it might be easier and less expensive to just find an LSJ F35 with the LSD option but if you already have the other trans maybe check with some Saab specialists in your area if they do trans work and get a price quote.

 

I have an extra F35 trans with a blown second gear, With LSD.

 

how many miles does the trans have ,and how much are you asking ,where are you located
