  • @IPGAuto im on bimmerpost (e90post) all the time, haven't heard anything.

    not that i every plan on doing 480whp anyways.

  • @DavidKneiber - Ok. Ask some E9X N54-T owners on E46Fanatics, BimmerFest, MFest.. they will all tell you they've hit some kind of issue. Slipping. Failure. Rebuild. Or just straight sold the car.

  • @IPGAuto nobody has yet to "upgrade" the ZF transmission on the 335i. everyone running high boost has been just fine. even hotrod182's transmission never skipped a step again :)

  • Ouch! This is why I always opposed tuning an automatic and smg, the clutche packs, drums, and so on are not developed to take anymore power than factory. The reason you don't see other E9X 335i trannies going out is cause the other 335i owners get a performance valve-body at most they'll get a performance rebuild kit with stronger drums, clutch packs, and such. Manual or go home. Cheap to fix, stronger than other transmission and can take the power and abuse.

  • hotrod182 said that this was a failsafe mode where the transmission shifted into 3rd gear. he also said he's done 30+ runs after this incident with no problem what-so-ever. it's nice to know the facts!

  • im sure ur transmission was finished after this right? did bmw fix it?

  • did you ever fix your tranny or did you get rid of this car for the 335d in your other vids?

  • Just listen to how the tranny shifted to M2-M3-M4 thats not normal for a Tranny on the 35i engine.

  • @bulegold56 I think the best and safest way to go is through Dinan. Don't they increase the boost from 8.8 to over 13 psi with their stage 3?

  • @thepublandlord1 hes shifting manually. Notice M2, M3, M4.
