Where can I get a new lnf tranny other then gm? Gm is back ordered and I have 500hp at the wheels and keep eating through all these pre owned trannys.

You will most likely eat through new f35s as well without some changes

adunk25

What do you suggest doing?

I think you need to look closely at the tune you have

06_ion2

Turn the boost down for when kill mode isn't needed

adunk25

I had all the work and tune done at zzp boost is already turned down to I think 24 psi

adunk25

Where can I get a new f35? Is there a certain type of f35?

Crateenginedepot might have some if your willing to pay the price

That or pay to have a machine shop make custom forged parts. Would be extremely pricey though.

john powell might be the guy to talk to, if he doesnt have a transmission source one and get him to install a set of 4.45 gears that will be your only hope keeping the that f35 alive

I guess the f40 swap is possible if zzp is still offering the kit. It would probably be more cost effective than going through multiple f35s.

Last I heard fsmr bought all the remaining f35's that gm had.

I'd try to find a 4.05LSD and ramp the boost a little more

Well that sucks if fmsr got them all we are doomed

I heard gm had manufactured a few more and that ced had some new ones it stock. Don't know if that's true.
Op you should try what someone else suggested and give Powell a ring or pwerks in Chicago to build you a cryo treated 4.05 or 4.45. That's your best bet along with boost ramp.
A new one isn't built quite stout enough for your hp you will have to upgrade the internals.

John Powell will suggest a 4.05 trans. 4.45 is hard to find. I just got a 4.05 shipped out to me. Do you have a boost ramp on ur tune? The torque spikes is what kills the trannys. That or go with a 6 speed f40 and also still boost ramp.

swap in a f23

Why would that benefit him?

Longer gears, more options, cheap as **** to replace.

F23s have shorter gears, but they are a ton stronger. Axle options are limited tho

I had Driveshaft shop make my f23 axles, haven't had a problem yet. Was $200 plus I sent them a set from a junk yard.

you mean $800?

Well I was the first one done.

Why is f23 so much stronger? Is Gm mental? Put stronger trannys into cars with less power?. I have one sitting in my shop

Yes they are mental
