I did a 3x3 and it might be my fault that maybe more than 3 qts came out and I just need to add a little more fluid. But when I had amsoil in there as I dorve I could not even feel the car shift, maybe because of the friction modifiers but since redline has little to none, is it normal for us to feel a slight bump or thrust (very faint) when the car shifts because it doesn't have these friction modifiers? I know it's better for the transmission but miss the smoothness!

 

Yeah, I feel it. Especially when it's cold. It doesn't bother me though.

I'm using Type F.

 

Yeah thanks, I would like someone like I Hate Cars to put his input on this. I've read through the threads and read that everyone saids it shifts better and smoother, in essence wouldn't it shift harder because there is no friction modifiers?

 

yea it only happens for me when its cold. im also using type F. im completely fine with it though and dont regret it at all.

 

All else being equal, the harder it shifts, the less wear is occuring. You want the clutches to grab quickly when it shifts and not slip into gear. It's the same with a manual transmission. If you were to ride the clutch and release it very slowly after you've already applied the throttle, you wouldn't expect it to last long. That's basically what's happening with Z1. With the Redline it's the same as popping the clutch quickly between gears so there's no slip.

The exception to this is a "bump shift". This is where it shifts super slowly and then finally grabs all at once as the shift is completed. Mine did this on the Z1.

Have you done the switch replacement yet?

 

Yes I've done both switch replacements and 3x3 flush, I added in an extra quart as I saw the fluid was below the low dot, hope that is ok.

 

as long as it isnt overfull on the dipstick

 

You can overfill a little. Mine is always a little above the full mark, no problems.

 

I Hate Cars, I don't know if I installed the switches flip flopped, I don't think so because I matched the color of each before putting it on, didn't have a computer to double check part numbers at the time, but it feels like it lunges the car forward then shifts and you can feel it, it's quite annoying actually, anything I could do? Do you have this issue too after switching? I know that it's grabbing because of no friction modifiers but want to double check if this is normal, like I can feel third/fourth lunge and shift into the next gear.

 

The only time it lunges is at full throttle. You absolutely can't feel the shifts in mine. I've closed my eyes with the gf driving and if you couldn't hear the engine you wouldn't know it shifted. However, it shifts extremely quick and snappy. Probably 3x quicker than Z1.

You might double check the switches.

 

can the switches be flip flopped? meaning can they actually fit do you know? The only way I knew how they went was compared the color of the plastic for the clip to go in, they matched each one.

 

Update: it seems around up till 3-3500 rpms but when it shifts after that then it's smooth. Ideas?

 

Don't know if you can tell if my front mount is good or bad?


Btw does the intake have to be removed for a timing belt and water pump job? This is what I found, but it could have been me over tightening.

 

In your second pic, the upper hole is filled with fluid. To me, this indicates that you are full or overfilled.

In addition to those holes in the dipstick indicate "Low" and "Full", those holes also serve as a backup visual reading. It is hard for excess fluid along the guide tube to be able to form a puddle within one of those holes. To form a puddle within one of those holes requires being completely submerged into the fluid

 

During the cold the shifts are rough as in one solid grab which is good compared to slipping but it's kinda like thump after each gear and softens when warm. Like without looking and hearing I feel it shift when IHC said he couldn't feel his at all leading me to believe mine is not supposeto be like this?

 

according to your dipstick pictures it shows that it is full!!!

 

Lol now I know after I looked closely. It's way over filled.

 

I have this same issue with mine after I did the 3x3 with the Type F on my car. My wife has even now mentioned that she feels it lunging. Now with mine I only feel the lunging when I am just causally driving. When I romp it, it feels smooth. I switched the fluids back around the end of November, this lunging has started to feel more and more pronounced. I have about 3.5K miles driven with the Racing ATF now.

Since my car is a 2007 I never looked in the 3rd 4th gear pressure switches, should I look into doing them before going back to the Redline D4 or whatever is the recommended other fluid? Do you think the switches will help at all with the car? Fluid levels are at the proper location on the dipstick.

The car has 44.5K on the OD, the first transmission flush was with 40,866 miles on the car.

 

I am glad you posted this. My dip stick looked exactly like usmarinedelta and I was kind of confused, since the fluid thins out significantly from the bottom. I think you really do have to read the holes. If there is fluid in the hole, then it means you are there. My tranny is also slightly overfilled, by 0.25 quarts. I know since I was topping it off 0.25 quarts at a time. Runs great though.

 

Just did a 3x3 w/ 6 qts Racing ATF & 3 qts Lightweight Racing ATF. I can feel the shifts if I pay attention to them. They're not harsh or hard shifts, just feel authoritative.

 

what is a 3x3. What fluid should i use. Any Help? Royal Purple Redline stc which one is the best.

 

Read the thread titled "Racing ATF" and "very interesting conversation with my trans builder". I'm not trying to be rude but this has literally been gone over 1,000 times.

Long story short, Redline "racing" fluid or any "type-F" and replace your 3rd and 4th gear switches every 2-3 years and the trans will last forever. Wait too long and it will be burned up before you know it. The reasons why are in those two threads.

 

Mine also does this while the engine is warming up. Can anyone confirm if this is normal or not? Having driven older mercedes in the past I am used to a car needing a few miles before it shifts normally so I assumed it was a non-issue. But, I would say this is the only issue my 3x3 and pressure switch change did not "fix"

 

Ditto! I did a Mobil1-EP oil change at the same time. My 04 with 66K miles has never run smoother. It shifts smooth and fast, no matter if I am in city traffic or WOT. I had done the switches a couple of months ago and that made a big difference on when it shifts but the Redline F makes all the difference in HOW it shifts.

 

Well some people say it's normal but I Hate Cars which is a tl guru said he can't even tell when it shifts which leads me to be concerned. But it does make that the fluid should shift firmer because the lack of fm.

 

Bump

Sorry to bump an old thread a quick google search pulled up this thread. I can't deal with the lunging that I'm feeling with the RL Racing ATF 1x3 done.

I have been using D4 for the last 30k miles. My car is just past 150k miles and I decided I wanted more quick, crisp shifts that everyone was mentioning for the Racing.

Well since I bought the fluid locally as not too many places carry Redline, I didn't want to take it at the quicklube places(bad experiences there), so called my local dealer to schedule me in for a Saturday. I bought the fluid that very morning.

They scheduled me in, told them I needed an ATF drain/refill done on my car but I would be supplying my own fluid. Bought 3qts Racing and 1 qt. D4 just to be safe since my cars sometimes drains 3.5 qts or just a lil over 3qts.

Well my dealer used 2 qt racing and 1 qt D4 when I told them to put 3 qts Racing. What's done is done, now I am worried that tranny is on its way out? or is it normal for the first 1x3 change to show such rough shifts?

Sometimes on light throttle it shifts right before 2k rpms and when its WOT its around 3k rpms. It works up to the next shift point then car jerks/lunges me a bit when it does shift.

I thought I would feel the better shifts but doing this 1x3 change is rough, so I know I need to do another change in a week but will it always be this rough?

 

Lunging with Type F fluid usually indicates the switches are in need of replacement.

 

I changed the switches out like less than 4k miles ago. Do I really need to change them out again even after I have new ones in? Or would you suggest doing another change to see if it will help?

And it happens on cold start and when the car is already warmed up. It feels worse than when I had the DW-1 in there only difference was shifts took longer to change creating the lunging affect as opposed to Type F shifting soon and rough. With D4 it drove just about right but shifts could have happened sooner which is why I started to do the 3x3 process with Racing than 2qts Racing and 1 qt D4.

 

If the car is up shifting at 3k rpm at full throttle as you mentioned earlier, it's not the fluid you need to worry about.

 

Ahhh dont tell me that, interesting that I had my heater was on and the car was shifting fine, no problems and its so strange.

Today its been shifting fine no problems, they shift around 2-2.5k rpms on light to mid throttle. So hmmm... its so weird.
