Lost 3and 4 --
Uhmm, anyone else? I have this same problem. Spraying a 200 shot, when it went to shift, bam all of a sudden rev limiter, so.. rolled to pits and packed up. Driving home, again, no 3rd shift, free spin and thats that. Happened in a matter of a run.
1)No codes, so I am thinking it is not a solenoid stuck open/closed.
2)With this be primarily the 3-4 band, or clutch pack? 3)Could it be a pump problem? Still PN and then either 1st, 2nd gear starts are fine, and shift from 1st to 2nd normal??
4)UGH!
Thanks for any info.

Same thing in 3rd gear.
The 3/4 clutch pack is held in the input drum with a lock ring, and I blew out all but two of the teeth that hold the lock ring in.
Whatever it is, it's the 3/4 clutch pack. If you need a new input drum, it's $286 brand new from GM, Dal Slabaugh can get it for you for $182, but I hope you're not in a hurry.
There's a also a place called the transmission center www.transmissioncenter.net , they sell a hardened input drum and shaft.
Also, if you have a pre-2001 transmission, you'll want to get the upgraded reaction shaft and sun shell. There's a bunch of parts that are available for upgrading, I can get you a list of parts, and where I got them, if you want it.

I think what you're referring to is the stripped teeth on the sun shell, and if that happens, you lose Reverse, 2nd, and 4th.

Verdad Gallardo yeah, mine went south without notice either. Just wailing down the quarter around 96mph when it went for second and just didnt find it...and the nitrous never helped.

well its just 3-4 first and second are fine and hit hard --3-4 just isnt there at all --it seems like a tranny psi issue or something -they never slipped prior to this --i would think if it were a clutch pack it would slip --what tells the tranny to engage the clutch packs on 3-4 --thats what i think is wrong - i am unfamiliar with this tranny and i dont know what components do what job
the way it went out is like a seloniod went out or fluid blockage-it worked fine then it didnt at all--- weird

If there were a line pressure problem, you would have slippage in all gears. In 1st gear, both "A" & "B" sol are on. To shift into 2nd gear, the "A" sol. is shut off, the "B" sol remains on. To shift from 2 to 3, the PCM shuts off the "B" sol also. The movement of the "B" actuated valve sends pressure to the 3-4 clutch pack. If you have 1&2, BOTH sol. are working.
If all this begn suddenly, you may have a front sprag problem. In any account, it is not as simple as dropping the pan and replacing the solinoids.

Hey guys, haven't posted in a while. I've been gone a while. I too have lost 3rd and 4th in my stock A4. Has anyone here ever used a Level Ten Performance Raybestos rebuild kit? I am thinking of installing this kit, a shift kit (probably a B&M), maybe the Level Ten Hydrostorm Kit, a Vig 3600, and a tranny cooler. My question is, Are there any other components that I may as well buy or should upgrade while I'm in there? I am in the National Guard and will be deploying at the beginning of the year and my dad and twin brother (my dad built ASA cars for years and owned his own garage for years after that and my brother is a school trained mechanic) will be doing the work for me while I am gone. I would like to have as many of the components on-hand as possible to keep them from spending any of their money on my repair. The fact that they are going to do the work without me makes me feel guilty enough. I would appreciate a comprehensive list of notoriously weak components or common components that typically cause this problem. Thanks a bunch. 
I dont know, but what I did is read about the components in the Cmotorsports transmissions---->
Pretty good list if you ask me. But sometimes its how it is set up as well. With all that experience, I cant see it being out of their league. I am heading for Afghan, last thing I needed was this trans going out, but I had it on a list of "what to get as I am gone" for the wife to tend to. Guess it came early.
Good luck.
Charlie.

Rick, what state are you in? I'm in CA ANG. You heading off to Iraq, Afghanistan, or "other"? Good luck on your "vacation". I got back in April from 5 months in Turkey and 2 weeks in Iraq.
About the upgraded parts, GM has 5-pinion planetaries, and an upgraded reaction shaft and sun shell.
Let me dig up my list of part numbers, etc., and I'll give you the list of parts that I stuck in my tranny. I ended up replacing my input drum, input sprag assembly, input planetary, reaction shaft, reaction sun gear, sun shell (non-GM), and reaction carrier.
Also, I ened up using Raybestos High Energy frictions, with .060" steels, so I managed to fit 8 frictions ans 7 steels in (stock has 6 frictions). I had to get two sets of High Energy frictions, and one set of Kolene steels.
2001 and up 4L60Es come stock with the new reaction shaft, sun gear, and sun shell. The new reaction shaft using torrington bearings instead of thrust washers.
I also went ahead and replaced all of my solenoids, just for good measure. The kit that my tranny guy got has an adjustable line pressure solenoid
.
Oh yeah, and the M32 transmission, which is a 4L60E, but on the 6.0l Silverado 2500HD 4x4, has a deep pan on it, and it's like $35.
Like I said, I'll dig up the list of p/ns for you, and I'll have to get them to you next week.
Charlie, are in the 25th Light ID? Let me know if you want aparts list too.

FYI, all 'line pressuer solenoids' aka 'force motor', including the OE one ARE adjustable.
The M32 is in fact the 4L65E! It DOES use the same pan though. All 4x4 and HD Chevy and GMC trucks with the 700 R4/4L60E/M30 have the deep pan and should be available @ any Chevrolet/GMC dealership. Remember, if you add a deep pan, get the filter for the truck application that says, "With deep pan"!

CAT3 and Guardsman, I am in the IN Guard. I am a Cav Scout (19D) in an infantry battalion. We are supposed to be going to Bosnia near first of the year, however; no orders yet. Rumors are running rampant. By what we are being told we ARE going somewhere, where is what all of the rumors are about. Bosnia sounds fine to most of us given the other options. CAT3, good luck, be careful! Guardsman, thanks for your service!
Oh yeah, thanks for the tranny info as well!!
