Default best 4l60e mod

I have been having problems with the 2-3 shift hitting the rev limiter. I replaced the stock servos with a billet set to see if it would have any effect. I am amazed at how crisp the shifts are now. I have tested it on the street and am eagerly awaiting to see if I can make a full pass on the bottle at the track without any problems. So far, so good.

the best mod for the 4l60e is to remove it.

"a4" does not mean 4l60e, as there are many other automatic transmissions with 4 forward gears.

The install was tight as I had to unbolt the cross member and let the tranny droop on it's own. I then still had to gently pry the tranny away from the tunnel. As far as ease goes... if you can do a tune up then you can install the billet servos. My experience so far has exceeded my expectations. Keep an eye on my sig next week to see if I net any improvements at the track. I'm looking to go better than an 11.5 in the 1/4 mile. The best in my sig was having to let off 2 or 3 times to get it to shift into 3rd.

This isn't the name brand that I used but is almost exactly the same as what I used. This give a pretty good detail of the installation.

any updates?

the trans in the camaro needs a fix...IMMEDIATELY.

i did a test:
not stalling up the verter, leaving off idle the 2-3 shift was tight, crisp. (like what i want)

but if i load the verter and stall it up and launch the 2-3 hit is WEAK! lags....frustrating. UGH!

The billet servo is fine and we use them in our level 2 and 3 unit however be warned that the stock band pin area cannot stand the force vey long and will tear through after a bit resulting in loss of 2nd and 4th , We do not suggest the use of the billet servo either sonax or superior with the stock band ,

I went to the track Tues. Made a motor pass and shifted fine. No hitting rev limiter. 2nd pass turned on the bottle=hanging in 2nd still and hit the limiter. I am now looking for a complete core as cheap as possible, locally so I can build it. My tranny builder is going to teach me how to build a 4l60e.

this is your 6th 4l60e, nice going. for every ONE guy running good power successfully with a 4l60e, there are 15 that are on their 2nd or 3rd "built" 4l60e still bitching that it slips or is broken.

Yeah, that's probably because the other 15 guys went to the wrong builder.

A 4L60E trans + some time at FLT = an excellent 4-speed auto trans.

Just got back from the track with the m6-a4 conversion. Mine bounced off the rev limiter everytime from 2-3. This is a built dr-evil stage 3 trans. Other than that it felt perfect. What could be the issue?

All in time my friend. But for now i need some good times out of the dr.evil. I am really confident the issue is not with the trans. Ill take you for a spin in it when i see you next. I believe its in the tune. Its going back to FLP on the 14th.
