I think my trans is skiping 2nd gear, it only seems to do it when I am just litely on the throttle. Is it the nut behind the wheel or what.

How many rpms are you at when it shifts?

--- Update to the previous post...

For example 2500 rpms in 1st would equate to just under 1000 in 3rd with the converter locked, 2nd would be 1500 unlocked.

I will have to check my rpm's. But it's no where near 2000 when it shifts the way it does. I can be in town lite on the gas and when it shifts I can feel it lug for a second then it down shifts and then up shift on thru the gears. I had a old pontaic 428 with a 400 turbo with a shift kit and it would do that when you just barely had the throttle cracked, it would up shift like it skiped 2nd and then down shift back to 2nd. This reminds me of the same thing.I am kinda worried about the trans due to when I changed filter it was kinda dark looking, but not burned. When a trans is burned it will smell like a house fire, right?

That fluid looks like it has been HOT, but not sure on the burnt smell.

I am going to send it off and get a report on it. I dont like the way it looks either, I will let you know.

Hey JL yeah looks a little hot ..... do you have a tranny temp guage ??

No gauges yet. Trans pan was spotless, magnet had small amount of material on it- looked normal. The truck had 37k on it when I changed it. I dont think it was ever changed. I have a oil sample ordered and we will see what they say.

Did the slipping fix itself after fluid/filter change ?? Does it have a modified valve body ?

Trans has never sliped that I know of.

sorry - skipped 2nd do you have a stock VB ?? And did it stop after fluid/filter refresh ?
