I have been having hard 1-2 gear shifts and sometimes it felt like downshifts were going to rip the truck apart. I cleaned the MAF tonight and took the truck out. It feels soooo much better! It shifts much better than before the cleaning. I am 100% stock so I assume until I get a tune it will still shift semi-hard. I'am just happy it's not shifting like an epeleptic at a rave anymore!

Thank you to the TBSSOWNERS.com family for the tip! :bigarmhug:

I wish that worked for me, tried it twice and no luck. I usually let off the gas while it shifts to prevent the hard shift.. annoying.

This happened to mine. It was the input speed sensor:2cents:

I think I'm going to try this over the weekend. Mine doesn't really shift too hard, but sometimes it will shift harder than others. Maybe the MAF cleaning will help.

I have similar issues as everyone explained. Shifts hard and sometimes I think it doesnt know what gear it wants to be in, has around 60k. I also let off the gas at times to reduce hard shifts. Will try Cleaner and post results. :beavisnbutthead:
