Is the a difference between full size and s10 trannies?

hey everyone,
I have a 97 blazer 4wd with a 4.3 and the 4l60e. It looks like the front pump seal is going on the tranny and I'm debating on wether or not I should try to fix the seal or put a rebuilt tranny in since the truck has over 150k. That's another discussion however.
I've been watching craigslist and there's a few 4l60e's that were rebuilt from full size trucks (Burban's silverados) that are a decent price. I'm pretty sure one would be a direct bolt in but am wondering if there's any other differences I should consider or models to stay away from. Would I have any problems with the blazers transfer case and or driveshaft length? I'm assuming I'd want to keep the blazer torque convertor or do the full size use the same stall speed?

Thanks for any advice,

there was another thread on here about this and everyone pretty much said a 4L60E is a 4L60E no matter where it came from

Case is the same, clutch packs are not the same. Full Size trannies have more clutch plates...

they are the same,if the s-series 4l60's were weaker they wouldn't be a 4l60,the 4 is for a 4-speed,L is for longitudal mounting, 60 is the rating for how much power it can take,and the E is for electronically controlled.

you will want to keep the 4.3 convertor since it will have a higher stall speed.

Try to keep it with the same yr for better chance it working.

The only diff I can think of maybe the output spline count, but I am not 100% sure.
