Thanks for the excellent Gary

Really burnt that mercedes doesn't offer the K1 and K2 o rings without buying the new drum. I'm stuck with having to source an old stock SMS kit off ebay or measure the o rings and buy some myself and hope their the right compound. Erling kit does not have these seals.

[@GaryFerraro]

correct, cannot buy single seals, i'm don't even know anyone that does

Hey Gary, great video! I rebuilt a 722.350 and wanted to ask you a question about tuning shift firmness. When i accelerate at around 2K-2.5K RPM the trans shift smooth. When i accelerate with 3K-3.5K rpm the shift is pretty firm, definitely more firm than the 2K-2.5K situation. I found that if i let off the gas a little before it shifts, the shift is perfect @3-3.5K RPM. I have a new vacuum modulator tuned at 30mph as well as measured the vacuum into the modulator, i think its was around 18.5 which should be enough. Any ideas how to smooth out the shift at higher RPM's?

hi Gary i got the original kit from Mercedes for 722.317 and did not get the seal and screws for the k2 drum . is this something i can get separate if so where ?

[@GaryFerraro]

maybe google it, it may be sold as a kit, the one i have, i've had for 25 years. The kit would include the screws, the tap, loctite, and i believe the rubber seal, may have drill bit too

[@sonnysingh9432]

Gary Ferraro thanks for your quick response awesome!

[@maadenengineering9101]

Mr. Gary .we can do the same for the D1? and what if I didn't replace the o ring?

[@GaryFerraro]

Yes, K1 is alittle different, those screws have to be countersunk or they will hit the piston, they actually eliminated the rivets on the K1 drum and now use a snap ring. How are the other rubber o-rings soft? if they are, then you should be ok, im sure there are rebuilders who dont change that o-ring, also, make sure the drum air check ok.

[@andrewasbill3690]

does anyone know of source that tells you the order for the steels and clutches?

[@GaryFerraro]

for the 2 drums?

[@andrewasbill3690]

@@GaryFerraro Yeah! The K1 and K2 drums but particularly the K2 drum. I bought a replacement drum off of ebay but it was taken apart. So I dont know what order the steels were in.

[@andrewasbill3690]

I know that steels vary in thickness too so I'm not too sure about that either

[@GaryFerraro]

@@andrewasbill3690 ok are all steels the same thickness? You could also send me pictures [e-mail]

[@michanus1092]

Gary i am rebuilding my 722.320 and have used a m5x10 b olt (europe).Do you think if i torque the bolts enough without the loctite ,do you think the bolts will come out?Greetings Michael

[@GaryFerraro]

your speaking of the drum correct?

[@michanus1092]

yes the k1 drum is countersunk but on the k2 drum i have used like you a m5x10 allen bolt but without the loctite do you think the bolts can come loose even if i have torqued them enough

[@michanus1092]

To be sure i have bought the blue loctite and wil use that on the bolts (for the k2 that is not countersunk) But anyways thanks for the great videos you post you are a great motivation for most do-it-self rebuilders also in europe.Have given many people your link for transmissions and many have rebuild the transmission with succes.

[@GaryFerraro]

ok, i would recommend using it. Sorry for late reply, short handed today at the shop

[@garymullins6513]
