I am contemplating what I want to do here. I have a few options with pros and cons my trans is shot... Keep in mind I am a 335xi Dps take alittle more work... Sometimes I wonder why the heck I paid 3k for this warranty I guess modding was just to addicting to me and now I pay lol.

Option 1: Put my car back to stock BEF CHARGEPIPE JB4 7 INCH FMIC DCI VRSF CATLESS DP's Clear all codes and shadow codes. Then bring it in and have my aftermarket warranty hopefully replace my Transmission.

Pros: Free, Brand new transmission
Cons: Lots of work going back to stock, possible warranty denying the work, I have to keep running it hard and modded so it shifts slips under stock settings (may take awhile)

Option 2: Keep the mods in and pay $750 for a junkyard tranny without the torque converter out of a car with 68k and swap them.

Pros: No warranty worries, can keep the mods in, I like working on cars... somewhat mostly modding tho lol.
Cons: $750 out of pocket, Who knows what that transmission has been through, Alittle bit of work under the car with no car lift but I have good tools and (4) 2 foot jack stands but more work with XI due to transfer case.

Option 3: Rebuild the current transmission with a master rebuild kit.

Pros: All new parts in the transmission, Not having to deal with warranty
Cons: Few hundred bucks for rebuild kit, Would have to have my ASE certified Best Friend help me with it, Downtime with the car.

I would say removing bolt ons is easier than swapping a trans... but that's just me.

Turn the jb4 to stock map and take it to a trusted indy. Most of the time warranty repairs are approved over the phone. Should be able to get a transmission approved over the phone without a site inspection by the warranty company. If that option fails I'd go with #3.

This again?

So you think 3 bolt-ons and a tune is more work than replacing your 200lb transmission?

get under your car and take a good look at the exhaust, driveshafts, trans cooling lines, transfer case and most importantly the bolts that hold the trans to the block of your car. Do you have all the extensions necessary to get those bolts out without rounding them? If you round one of them off you'll have to pull the engine.

Option 3 is not even an option, imo. Rebuilt trans are a bigger gamble than low mileage used, plus all the work. Double negative.

You should be able to leave cp and fmic, those won't deny warranty coverage. Flash back to stock and remove dp's then get new tranny. You don't say either, is this bmw warranty or 3rd party, from reading around 3rd party rarely denies warranty compared to dealers.

[335xs2dinan]

Use your warranty

[mightbaal]

Ill just use the warranty I guess its just a PITA with the Dp's on AWD. I have like over 3 grand in tools the fmic tho.... I had to cut that clamp on both sides tho so I would have to use a coupler clamp or a hose clamp for the stock one. What size coupler clamps do zi need for that?

I wouldn't risk it. It clearly states in my warranty terms any modifications to the car will void the warranty. Now I have to fish around for my stock parts bolts and stuff mainly. What worries me is the wastegate flappers had a bit of play in them and I was getting some codes for like turbocharger air density and have 30ff shadow codes running 20 lbs of boost. It will be my next weekend project I guess if I can get the trans to act up under stock boost because on map 4 I dont have slippage problems yet.



Btw its a 3rd party warranty thru my credit union.

by law, denial of any warranty claim due to aftermarket parts must show that the aftermarket part caused the covered part failure.

In this case it can be pretty easy to do that. With those mods he is pushing a decent amount more power than stock, pretty easy to point fingers when the automatic transmission takes a dump here.

Not saying that's what it was, but I would still bet my own money on it.

I have seen so many people getting warranty denied for mods . You will have to take them to court and it can get expensive.

On paper yes the dealer is supposed to prove it , but in reality they can just deny it and you have to dump money getting lawyers ,etc ,etc to prove your case. Most of the time it is not even worth it ...

As covered in this thread, bolt ons are way easier than trying to replace a tranny, on top of that getting a certified transmission done by a reputable shop gives a lot more piece of mind rather than a home garage project and a tranny from a junkyard when it comes to selling the car. Just things to think about, I think the extra steps to take it back to stock out weight the benefits of a home job in the long run. I think your order of operations should run as option 1, option 3, and lastly option 2

[mightbaal]

See the problem I have right now is the transmission acts up only when I am FBO on map 7.... If i go to map 4 (stock boost) the transmission is fine.

[dannyhavok]

Stay on map 4 and don't spend a dime or any of your time removing mods?

[mightbaal]

Lol or eventually it will fail on map 7

[tlow98]

Have you tried swapping the fluid?

[tlow98]

Have you tried the Alpina trans software?

At which point you tow to your house, swap parts, re-tune and take in for service?

Yes but it will eventually start acting up on map 4 and still be driveable (hopefully)... And to answer some other questions no I have not replaced the trans fluid if you start to have problems its probably to late so it would be a waste of $200 (diy). Also I had no problems with the car until I flashed the Alpina B3 v2 software after that... It started a week later. Since then have qent back to stock flash on the trans. Tbh the alpina flash made wot shifts hard esp the 1-2 shift didnt feel good.

Wrong answer.... if you have cooked the trans fluid then you are definitely going to get slip. You may be able to flush twice and the transmission may recover.

Why twice? Because when you drain, you will not get all the fluid out. Only a percentage because what is trapped in the bottom of the torque converter. So, drain and then fill, run it some and then do it again. You will get ~60 - 70% of the bad fluid out.

That is unless you want to try and do the flush using the transmission lines going to the cooling unit with the engine running.

FREE and NEW. Seems like a no brainer.
