Guys,
I've been reading some other threads that says this is normal, but mine clunks really hard on my 08 sedan journey, even when i'm not pushing it that hard (like 4k rpm). The other shifts are very normal and smooth. You guys sure this is normal, or should i have it checked out?

Also, do those black betty grounding wires really help out that much?

 

It happens with my car too, dealer told my i shift at high rmp's (4k-5k), he told me its normal, its better to shift from 2nd to 3rd at lower rpm

 

I recently installed the BB grounding kit and noticed quicker shifts and better idling, however it still slams 3rd gear every now and then

 

Hey, I have exactly the same problem but could not figure out why.

2nd to 3rd gear in DS mode => loud clunk sound. All other gears smooth and no sound.

What's dealer's explanation on this? Nobody seems to worry too much, but it just doesn't sound right to me.

bionicg35 => what's BB grounding kit?

 

BB= Black Betty

 

I am mostly know for my V35 kits but my V36 kit is just as effective. Check out one of my recent customer's reviews:

i might have to pick one up

 

2>3 rd gear clunk/rough shift.. ect is 100% normal for the 5AT.

 

I really dont experience any clunking when the car shifts at any rpm other then when i reach the rev limiter under hard acceleration - but even this was slightly fixed when i installed the BB grounding kit

 

I have the Black Betty set and I've been very happy with their results.

With that being said, a grounding kit will not do much for the hard shift into 3rd.
The only fix is to get to know the car a bit. Once you get a feel for when and how it occurs, it's fairly avoidable.

 

old thread but this had me a lil worried but everyone says the same thing...shifting at high RPMs will cause this. BB is my fellow team mate and his kit helped to alleviate this a little bit, it didnt take it away completely but helped.

i may just go ahead and get the Transgo as well

 

BB is the only way to go
