Hello,

I have a 4l60-e that has a very hard 1-2 shift, only on the up-shift. I was thinking that it is the shift solenoid, but I am not 100%. The previous owner was not the first owner and mentioned he thinks a shift kit may be installed, but every other gear change is not as hard as the the 1-2. Is there any way of easily checking the shift solenoid? Where is it located?

Thank you.

It may also be the tune if that has been tweaked at all. My Frost Tuned A4 had a VERY hard 1-2 shift.

Thanks for the response!

As far as the tune is concerned; I am almost certain that it is stock, but I will most definitely investigate.

This could be normal, if in fact a shift kit was installed. I've had several built/shift kitted automatics, and the 1-2 shift always feels harder than 2-3 or 3-4....just how much harder has depended on the specifics of the kit installed.

If nothing has been modified within the trans or the tune though, then 1-2 shouldn't feel any different than any other gear change.

I plan on getting a Frost tune soon. If it shifts hard after the tune, will that cause any damage or will it be ok??

Well, before you get a tune you should determine if it has a shift kit in it. That will affect how it is tuned. I suggest having somebody who is knowledgeable about shift kits do a tranny service and inspect the valve body for shift kit components.

I honestly thought my Frost Tuned A4 shifted a little too firm from 1-2...it was great under hard acceleration, but under normal driving it could be pretty jarring. I ended up getting used to it and lifting when I felt the shift coming, to ease into it. I agree with Rev, you need to first find out if anything has been done to alter the tranny before having Frost do his thing.
