RE: 07 tranny probs?
Just a note to those of you going with non-HD oils in the transmission......because of the noise in my transmission, at my 1000 mi service I requested that they put the Redline product in vs the HD product--I just feel that although HD says otherwise, different components of the engine should have different oils to handle the different heat tolerances, friction diffs and different thicknesses of the metal parts. I wouldn't put transmission oil in my car's crankcase so why would I do it to an expensive bike with a sophisticated engine? I got a call from the service dept manager a couple of hours later asking if I realized that using any oil in the transmission other than HD's SYN3 may void any warranty on the transmission later. With what we're hearing in these new transmissions and the gut feel that we're heading for a recall or mass fix of some sort I pulled back on using anything else. I figure I'll play it by the book on things like this and wanted to pass this along to anyone out there thinking about putting different oils in besides HD's product.....I'm curious if anyone else has heard this from their service dept's with regard to SYN3 and warranty issues later on??

Installing a SERT on mine and even with the slipons I still hear mine chattering away loud and clear. On a positive note, once I came to my senses and stopped trying to keep the rev's up all the time so I didn't hear it, I noticed a huge diff in my miles per gallon. Hmmmm.

Well here's one more doing it if you're counting. For this much money I'd like my ride to make noises that are acceptable and reasonable. How fast would you take a new car back to the dealer or complain if you had an issue with it and it was new? Why should we settle? I'm tired of hearing things like "it's a Harley, get used to noises," or "it's because of the way the teeth are cut," or the myriad other reasons that are being offered up by those lucky enough to not have this noise as to why we should accept it.

RE: 07 tranny probs?
I just finished reading the 28 pages of posts on this '07 tranny probs thread.
I took delivery on an '07 EG Classic at the end of September. I only have 1000 miles on it because I am coordinating the 1000 mile service and putting the bike in winter storage. I'm switching to synthetic through out with the service.
I hear a hammering in 5th and 6th at 2000 to 2200 rpm or so WITH THE DRIVE TRAIN UNDER LIGHT LOAD - running down a level road at constant speed. Give it a little gas in that rpm range (what I would call LUGGING) and the rapping disappears.
I've only had one other HD, also an FLHTC, but I rode it for 17 years so I don't consider myself a Newbie. I find myself compensating for the noise by keeping the revs above 2400 rpm. I say compensating because this is not the relaxed cadence that I enjoyed with the old one.
I'm going to discuss it with the dealer when I bring it in for service. I'm going to make sure it's documented on work orders for future lemon law or past warranty coverage. I am confident that Harley will stand behind their product and have a recall if necessary. Maybe they'll handle it like they did the '06 fuel injector issue.

RE: 07 tranny probs?
I would say hes very close on HP #s on the 96.Many others have said the same thing.The 88s arent correct.If it is as easy as replacing the compensator setup this whole thing wouldve been over.If its due to final build clearances on a final bike build Im not sure how they will correct this easily,or cost wise.The factory couldve tightened specs up across the board on the newer releases and quieted this noise down or by the sounds of it eliminated it.This is a guess of course and dont read anymore into it.No way of proving this.I would also like to know if the lifters are still Delphi made units since my noise sounded more top end related as witnessed on dyno and has been a clattering noise on past yrs that too made this type of noise at certain rpms.

AMS Johnson-Hylift Lifters
for all Twin Cam Harley engines
From 1999 - 2001, Johnson-Hylift supplied lifters to Harley-Davidson...
Johnson-Hylift designed and produced a special piston and valve body
to work across the temp ranges and varying oil psi typically encountered
on an air-cooled engine such as the Harley. Since late 2001, HD has used
Delphi brand hydraulic lifters. That's why there was a Harley p/n change
from 18538-99 to 18538-99A and now 18538-99B. However, Delphi did not
use a 0.655" hi-volume / hi-pressure plunger piston and valve body
specifically designed for Harley as found in the Johnson-Hylift lifters.
Instead, Delphi essentially used a small block Chevy lifter. The main
difference is the Delphi lifter tries to boost the hydraulic psi by decreasing
the piston diameter, but this leads to a smaller high pressure oil reservoir.
The volume is too small and allows the lifter to clatter. That may be why
so many of the late model Twin-Cam bikes are noisy. After doing some
research AMS learned these Delphi version 18538-99B lifters are made too
small to stand up to Harley's heavy valve spring pressure. The oil reservoir
inside the lifter is too small. It doesn't hold enough oil to let the lifter bleed
off under normal use and still have a cushion of compressed oil to take up
valve train slack. Note: ALL lifters bleed off during operation and even
more-so when the bikes sits, engine off.
The 07s use p/n 18538-99b a dephi version according to parts manual.
