I have the f35 trans with the lsd when ever im in 5th gear under deceleration on the freeway it pops out of gear but when im doing city driving it wont pop out of gear it dont make any noise either when in any gear

 

I like top gear better to be honest. Fifth gear is just a knock off.

 

you need to isolate your issue more, what happens differently when your highway driving that doesnt happen in the city..

 

it likes to pop out doing about 60-80 mph

 

syncro's... are you forcing it into gear at times? are you doing WOT pulls in 5th?

 

agreed. the american one sucks tho...

 

no im not forcing it into any of the gears and no just cruising on the freeway in 5th gear

 

in my HHR if I am going over 80 it will not go into 5th until I slow down around 65-70.

 

I'm thinking a bad synchro as well. Strange for it to be 5th though, that's not usually a common one to go.

 

im thinking the synchro too but i was just hoping it was going to be something cheaper to fix

 

If they were more plentiful, would probably be cheaper to buy a salvage one than pay someone to crack yours open IF you can find someone other than the dealer to do it. But given that you have the LSD tranny and they don't pop up that often, probably not gonna happen. Best bet is find one that grenaded something else and use it as a donor for the synchro you need. No idea what a new one would run you, but I'm guessing it wouldn't be pretty.

Or just use this as an excuse to get one of the ZZP units.

 

i talked to zzp and the one on the site is for the lnf and no lsd. a new one is going to run about 2250 from gm and my trans has already been rebuilt by gm and there is not even 5000 miles on it yet because 2nd gear went out on it 2yrs ago .

 

Hrm. I would say look around for a used one first. Use car-part to look local, Morad out in Ohio (around Cleveland I think) deals with a lot of Cobalts and there's another one LKQ I think that salvages a lot of them, but they're eBay only and not local.

 

i didnt even see the zzp was coming out with staged tranny and when i emailed them about the lnf trans they didnt even say anything about staged ones coming out next month. so im thinking about the stage 2 one they have i just wonder how much thats going to cost
