4l80 newb

For the most part I think it should. things you need to watch out for is the internal harness may be different along with sensors / solenoids. also depending on what engines are driving it in both yours and on the donor. torque converters could be different.. and no do not plan to re-use your old TC. it's full of clutch material and debris from your old bad trans and will kill the donor.

keep in mind that the bell housings will also be slightly different. iirc 01 used a bolt hole at the top center and the 97 does not. unless I have that backwards. but you are downgrading from the upgrades that GM did between 97 and 01. tail shaft lengths can also be different as well and might not be interchangeable. your best bet is to have YOURS fully rebuilt and upgrades to last. that comes out cheaper and better in the long run. If you can get or make the tools required to compress the springs in the clutch packs, it's not that difficult to rebuild a 4l80. just needs to be done in a clean environment, so just setup shop in your living room while your other half watches you rebuild it and make a mess. that is unless she strangles you first LOL.
 
yipes! that happened to me while teaching my daughter to drive on the dodge pickup. wasn't at 60, but we were nearing our turn on a main road. I remind here to use the signal with cars behind us.... she reaches to the shifter and puts it in reverse!!!! we felt and heard the BANG CLANK and I panicked dropping it back into drive as quickly as I could. didn't seem to do any damage since the truck is still on the road today (that was several years ago it occurred). of course she freaked out as did I, but that's all bridge under the water now LOL.

are you experiencing issues now since this happened? if the truck is still moving forward and back, I would say drop the pan, look for debris, and replace the fluid and filter. I am sure it took some damage to the clutches but might be alright for a while. even pulling it apart, you might get away with just replacing the reverse bands and clutches as a fix, though you might as well rebuild it all since you'll be in there.
 
In 1977, maybe before. I tried teaching my wife to drive a manual transmission - 3 on the tree - 1965 F100 - i didn't think it was possible to go from 1st to reverse. It is. Luckily it was misty out and the tires broke loose

I learned to drive in a 1969 Chevy C10, three speed on the tree, 250 CU IN, 6 banger. Dad let me drive on the dirt road on the farm, from the start of the road, to where the state road started. It was probably a half a mile and had a pretty good hill on it. When I first started learning, I shifted straight up and scraped reverse more than once until I figured out about pushing the shift lever forward when going from first to second. Luckily, I didn't force the shifter into reverse, it scraped and made a heck of a noise. Dad chewed me out a few times, so I didn't try to shift to reverse while moving maybe just 2 or 3 times. I always liked that fast shift downward from 2nd to 3rd. I drove that truck a few years as a teenager, I tore up alot of dirt roads in that truck. Also there was a sharp curve going up to the high school if I hit that curve just right in 2nd gear, I could really smoke the right rear tire. Oh, the things we did early on in our early years of driving, ha, ha.
