i have a 2000 silverado with 80,000 on the engine and trany and it shifts hard from first to second gear i have dropped the trany pan changed fluid and filter still shifting hard any recomindations

Could be your trans pump not keeping enough pressure in the tranny or too much pressure. Either way that can make for hard shifts. the bands inside the tranny could be bad as well. What ever it is save yourself tons of money and remove the trans yourself and take to tranny shop. Otherwise they will wack ya on removal/installation

i am new ti this,but i do have question.My 04 chevy 4x4 has started getting TERRIBLE gas mileage.Ive had the truck over 4yrs,and i know what is supposed to do.Ive checked by the calculator.Its went from around 13 in town to9.5!!!has 144,000 on it.Any suggestions would be greatly appreciated..thanks!

thanks for the reply i was thinking it could be the tcc regulator or spring and ball valve in the trany but the pump makes sense also is there a way to trouble shoot my trany and narrow down what the problem is so im not just replacing parts untill it is fixed

Hey JC1DEY start a new thread to get answers to your problems. Dont threadjack!

back to tranny issue.

Trannys are very hard to trouble shoot without cracking them open which is what most trannys shop will wanna do, and charge you big bucks. If I were you I would remove the tranny and trade it in on rebuilt with all the updates and warranty. You can find them for $750 + core.

A banging 1-2 shift is a very simple repair and no, the transmission does not have to come down.

First, check for codes. If none are found do the following:

Drop the pan back down, remove the 1-2 accumulator housing and pull the piston. Check for a torn piston seal or broken spring, but moreso for a wobbled out piston hole, which is probably the culprit.

Now, if all these items are okay, the 1-2 check is bad (unlikely). This is where it starts to get dicey unless you've been into about a million of these things, because the valve body has to come down (you don't even wanna go there).

I think you're gonna find a bad 1-2 accumulator piston. Wish you would have hollared before you changed the oil because you could have repaired this thing in just 10 minutes.

thanks for the info im gonna check the codes and throw it up on the lift over the weekend hope its just a torn piston seal that would be a nice easy fix

Bunk. Any good transmission man can tell you what's wrong with it without even opening the hood.

Who starts these silly stories anyway?

I've noticed it too, just in the past few months. Think it is this crappy fuel we're forced to pay out the nose for.
