Hey guys
I picked up a 04 Buick Rainier 5.3l awd. It was skipping 2nd gear.
I got new shift solenoids in and it will now shift into 2nd gear. The fluid was literally black, not good. Looked worse out of the trans than on the dipstick, that's for sure.
New issue is sometimes 2nd gear will "hold" the power and sometimes it will not even try. When it does grab it will stay until redline like it should. When it doesn't grab it will free wheel like you have the clutch in on a manual. This is when manually selecting 2nd gear.
It will never "hold" the power when you have it in drive and let it power down shift. If it downshifts into 2nd under WOT it will just free rev.
It also will never shift it self under WOT power. Wont do 1-2 or 2-3.
I uploaded a few videos. I guess I didn't get one of it free revving with 2nd manually selected but its the same effect as the videos when its in drive and you command a downshift to 2nd. Filmed in mexico.
This is manually selecting 2nd gear and where it held power to redline like normal.
Downshift to 2nd then freerev
Another downshift freerev
I think it might be the servo? Since it is intermittent. I feel like if it was the band then it would never hold and it does most of the time and 4th would slip and from what I can tell it doesn't but its hard to test.
All the shifts are super lazy. I mean 4 second shifts.
I'll be able to test the servo for play probably next weekend.
Think this is the right track?
Any help is appreciated
