I just put a new valve body in my 2006 Silverado with new accumulator pistons and solenoid’s and now that I have it all put together I went to drive it and it seems like it is stuck in a high gear like second or third and it has reverse has anyone had this issue before, is there some thing to reset like a transmission module?
Just recently bought a 2015 GMC Sierra 1500 SLE 4x4. I am the third owner. Shortly after buying the truck the transmission grenade’d itself. I’m at 97k miles so still under the 100k mike power train warranty, however I was 21 days outside of the 5 year part of the warranty. I reached out to GM after returning from deployment to try and get some help and hope that they would honor all or maybe partial warranty. Needless to say no help from GM! Shopped around for shops to rebuild and ended just buying a remand one for 2.7k. So here are my questions:
1. Flush the current cooler or buy an upgraded one?
2. If I should buy an upgraded one then how big?
Also should I bypass the current one in the radiator to have a separate cooling system?
3. I’ve heard of people deleting the transmission oil thermometer to achieve a cooler temp. So say do this because heat is the enemy, others say the trans is built to operate at a certain temp.
3.What temperature is the best operating temperature?
4. Should I have the new transmission re flashed or swap the one from my grenade’d one into the remand one?
5. What’s the best way to flush the current cooler if I don’t change it? I’m afraid if I just try to flush it then it won’t get it clean enough and I’ll mess up the new transmission!
That’s all I can think of right now! Thank you in advance for your time and expertise!

Hello, I will be doing an engine swap in my s-10 fairly soon. The specific truck I have is a 1992 s-10 ext. cab 2.5l 4-banger, with RWD and a 5 speed manual.
What I am thinking for engine/ tranny is a Chevy 350 with a NV3500 transmission. It would be easier for me to find a 350 that already has a NV4500 married to it, but I have heard that it is difficult to fit a NV4500 in an s-10. I can't find any info for my exact model, so I'm asking if the combo of the 350/nv3500 will be a good fit. I won't be racing this truck, I just want more get-up and towing capacity. if you know of a better setup I am very open. also originally I was thinking of putting a 5.3 Vortec instead of the 5.7/350 but everyones been saying the 350 is easier.

My recently purchased '05 Silverado 1500 has no problem shifting except between 2nd and 3rd.
On upshifts, it shifts out of second, then there is a small flare, then it tries to engage 3rd, then it flares again, then it engages 3rd. It takes about a second and it's very consistent.
On downshifts, it acts pretty similarly but it essentially acts like it's in neutral for .5 seconds. If I'm in 3rd or 4th and I depress the accelerator, revs out to 4k or 5k and then roughly engages 2nd.
Otherwise it's perfect. No slipping, normal shifts, normal idle behavior, reverse works well, no noises or smells. The transmission fluid level and color is fine.
I did some googling and narrowed it down to the computer, valve body, or solenoid which is basically not narrowed at all.
Has anyone else had and fixed this problem?
