Where can I find upgraded transmission with the 4.05 or 4.45 gears. The google search has given me basically nothing and I cant find them on the powell website.

ZZP has transmissions but I only see the f40 6 speed. Not a 5 speed


Just trying to budget a future build
THanks

 

Due to low stock of 4.45 gears it's hard to find them but if there are any available john would be the guy to talk to. ZZP doesn't do a 4.45 anymore just the f40. Powell still sources gears and rebuilds both 4.05 and 4.45 (when parts can be found)

Email him at

He's one of the most helpful resources and is a great guy to deal with.

There are some 4.45 gears available in the classifieds right now as well.

 

Does anyone trust aamco to work on a f35 repair/rebuild?

 

Aamco's a joke in my book. That's just my opinion of course.

 

I need a rebuild and cant afford to send it to powell

 

In cases like this, you get what you pay for. Save up some money and go the right route the first time, or don't even bother doing it.

 

So would I just need to find the gears and thats it? Lets assume I have a ZFR. Would I need more parts than just the gears to not blow up the transmission?

You would need the gears for sure maybe lsd - don't know if that help but wouldn't hurt to have if you don't have it already. The best prevention is not to abuse your tranny. ie. no WOT in low rpm, NLS...

What does NLS mean?

Yeah I dont really beat on the cars I own so I should be okay with that. I just know nothing about transmissions. I would like to just send mine somewhere or drive to a place and drive out and they say "OK you can run 500hp and beat it up. More than that and it wont last".

Dont really like the idea of banking on part availability if the transmission does go then I just dont have a car.

Any idea why they stopped making the parts since they seem to be so popular?

 

NLS = no lift shift which I'm sure you are already know what that is.

Is your transmission in need of a rebuild or are you just planning ahead.

The issue with he 4.45 gears is they were never used in cobalt/hhr they are being salvaged out of different older cars with a variation of the f35 in them. So the parts availability is low due to salvage yards getting picked clean. Driving the price of then up as well. There wasn't an f35 directly compatible with the cobalt that had 4.45 gearset so they require a trans to be built for you. Don't cut corners on a rebuid you will waste your money. Powell does them at a very reasonable price and he knows what he's doing.

If you are looking to save money buy a 4.05 sssc trans and swap it out and use your stocker as a core if you ever need to buy a 4.45 trans
4.05 hold allot do compaired to even the 3.86. But it's all about how you drive the car. Nothing is indestructible.

A 4.45 is basically a stock trans with new gears. There isn't really any upgrades beyond a more forgiving final drive. It would just be new bearings and whatever wear and tear parts they replace with a. Refurbished gearset and. LSD (they are pretty indestructible)

 

Total brain fart on NLS...yeah i know what that is.

Just planning ahead. I really want a cobalt and if i ever get bored with the stock turbo and wanna rip I just wanna know how my wallet is gonna feel to do it correctly.

Thanks for the explanation man. I made some mistakes with a supercharged grand prix and almost blew my motor so the more learning I can do the better.

Just to clarify when you talk about a rebuild you mean just replacing all the stock broken parts. If I have a good working trans then add the gears and I should be good assuming that the rest of the trans is working properly. I get that right?

Also how much does powell charge for an install of 4.45 gears? Or a rebuild? I dont really wanna contact the guy and waste his time since I dont own a cobalt yet.

 

So assuming he has 4.45 gears available. And te transmission you send him as a core is not damaged once he takes it apart. I think it's 2300$ for a rebuilt trans. If your trans has an LSD I beleove he takes another 400$ off that price for a 4.45. Do not quote me on this as it has been almost a year since I inquired about it and I'm going off my memory.

I belove a 4.05 or 3.86 rebuilt trans with an LSD is is 1500 if your core trans is good and had an LSD as well. But I again stress that if he takes the trans apart and the gearset is damaged or the case is cracked the price will be significantly higher because he won't have a good core to rebuild.

 

3.82 is 1900, 4.45 if he has them available at the time are another $500 I think. $300 to cryo treat it also if you want it.

 

what is a cryo treat? (super delay in response because I did not see the last reply)

For those of you who sent in your trans to powell how long did it take? Asking because I dont have 2 cars

I have a cryo'd 4.45 from Powell. Definitely recommend it, it makes an LNF with a ZFR a real beast.
As for build time, I'm not sure. My car was parked for the winter when he built mine.

 

Powell is best bet but those other guys, fmrs or whatever , they have Em to and also have an option of custom cut gears if u got the cash. Idk exactly what that means but I'm assuming they will get u some gears custom made

 

FMSR is a joke. Especially compared to Powell. In fact they should not be mentioned in the same sentence - notice how I didn't

 

I wonder if mr Powell couldn't custom cut gears for those who are willing to pay

 

He has said it would be really expensive. I would love to go to a taller 1st gear and a closer 2nd. Absolutely hate 1st to 2nd gear. Way to steep for a turbo car. Can you imagine how fast our cars would be with a taller 1st gear that you didn't have to limit boost in?
