Hopefully you adjusted your bands while you were at it? I had my dealer change the solenoid when they flushed the transmission, since they had the pan off anyway. Not worth me dropping the pan to do it and then trying to re-use the fluid or worse yet, buying 4 or 5 quarts of ATF-4. But, they still charged me $175 to do it.

I could do a write up but I just used a cut-n-paste from manual I found on CF. The tranny was serviced by the dealer when I bought the truck > 10k miles ago, they bands should have been done then. I had everything to do the bands but opted to leave them alone. I've never felt anything that even resembles a slip....even with 12k of trailer behind me. If it's not broke, don't fix it:cool:. I ordered the solenoid from transmissionpartsusa.com, it was around $45. Don't know who makes it but it didn't look like the one I took out, the actual solenoid part looked different.

I need to change my solenoid also would love to find out what part you used (OEM or the GM upgrade) also didn't I read somewhere that there is another part that should get changed at the same time?

Mike do you have a write up for adjusting the bands on the 48RE?

Don

Just found it the OD solenoid.

Some say change the o.d. solenoid, some say change the pressure transducer. I only changed the governor pressure solenoid and my trans now shifts like butter. I got mine from transmissionpartsusa. It looks different than OEM but I don't believe it's the Borg Warner.
