Slipping 2nd gear 4l60e? Hey guys I went to get my 2000 transam h/c/i 4l60e trans 3200 circle d stall retuned yesterday and on my way I got a check engine light on car. My tuner told me it was a shift solenoid. We later found out 2nd gear is slipping but all the other gears shift perfect.
My question is what should I be looking for? To just get a trans from a sponsor on here like performabuilt or does this seem to be an easy fix since I still have all the other gears. It shifted perfect before.

This usually indicates the band is worn. You can often get a bit more life out of the trans by lengthening the servo pin. Here are a bunch of posts and feedback on this subject:

Agree Totally With Mrvedit. Very good info.
What else is done to the trans? The band is one of the very few internal parts you could replace without a whole teardown. Just need to drop the trans, pull the valve body and the pump. It's fairly labor intensive but can be done, although I doubt it would be worth it at all unless you were on a strict budget.
If you do what mrvedit suggests it will definitely lengthen the life of the band, but I would do a fluid and filter change as well. All that material had to go somewhere.
Best of luck, let us know how it turns out.
P.s. I didn't check all his links, but you can buy an extended pin, or use shims that come in most trans go kits (almost any trans shop in your area probably has one they would give you) to set clearance tighter if need be.

Nothing has been done to the trans. It was completely stock came with the car and I added a 3200 stall to it. Has been shifting fine. I’ll check out those links. My main concern is that I didn’t want to go through a bunch of trouble just to replace the trans in a few months anyway.
If the trans is stock and slipping in second it is very likely there is wear in other areas as well and it will need to be replaced or rebuilt, Making the pin longer might buy a limited amount of time but is certainly not a long term fix .
If your looking to replace it give us a call at the 888 number 9 am till 10 pm eastern time and we can discuss your options and what would be best suited to your needs.

Your LS-style converter will fit on any LS-style 4L60E.
In short you can definitely re-use the same converter.
And as PerformaBuilt says, lengthening the servo pin is just a band aid which might get you another 5000 miles or so.

Ok great, and this might sound stupid.. but does the car have to be retuned again after the new trans is put in?

No, a replacement trans will work properly with a stock-ish tune; a performance rebuild, e.g. from PerformaBuilt is designed to work with the stock tune. If someone tuned the original stock trans for much faster/firmer shifts (i.e. higher line and shift pressure) then the trans tune may need to be brought back to stock.
However your 3200 stall converter probably needs a tune (if not already); else you might get codes and limp mode.

As mrvedit said no you could keep same converter as long as its clean. And tuning would not be required unless someone has jacked the line way up or it needs tuning for the converter anyway.

Correct me if I'm mistaken here guys, but I usually only see a need to adjust the tune for shift points with a converter change on a performance rebuild. Line pressures, shift timing, etc I think should be left alone so the trans can do the work it was built to do. I may play with the torque management but always leave in 50% at minimum.
I went for a performabuilt level 2 in my truck with a circle D 3,200 stall. Great combo for me. Not buying a new converter will just shorten your warranty I believe. But as long as the thing is clean and ideally flushed somehow you will have zero issues and can use the same one.
It was pretty cool being able to light the tires up fro a stop just by mashing the throttle in a heavy as truck with big, heavy tires. Good combo, again.

I wonder if ls1tech members get a discount lol

A converter shop cuts the converter open, thoroughly cleans the internals (perhaps even disassembling it a bit), welds it back together and balances it.
I think a typical charge is $150.
Just trying to flush it is unlikely to get any/all of metal flakes out of it. Then you install a new trans, the metal flakes eventually come out and can damage the new trans. That's why trans vendors will give you a better warranty if you also get a new converter from them. (Some might not give any warranty if you reuse an old converter.)
