I know I seen a 100 things on what I’m about to ask, but I never seen a fix. A deer ram out and hit me and busted my trans coolant. I didn’t know. I drove it a 100 or 2 yards and it got to not wanting to shift. I pulled over and got my other truck and pulled it home. Put on a new trans coolant and the ole lady drove it to work and that morning it was fine. That evening it wouldn’t shift past 2. I changed the filter and shift solenoids and still the same and the fluid that was in the pan was clean no metal or anything. I don’t know what to do. It will go into park, reverse, 1 and 2 and I don’t know if it is going into 2 right. 45 mph is 2500 rpm. Anyone know anything that would help me out. Thank you

 

Please do a Search via the Google Search Engine (Results from this Forum will be produced)...

Type in the Search Box: "4L60E NO third fourth Gears".

Let us know what you find.

 

With the limited info that you provided; my best guess would be that the 3-4 clutch pack was damaged when the truck was ran out of fluid. Time for a rebuild.

 

this...

 

Sorry to hear of your accident and the damage it caused.
Yeah, most likely the 3/4 clutch is toast.
One test would be to unplug the electrical harness to the trans. This forces it into 3rd gear with max line pressure. If it doesn't move, its pretty much guaranteed the 3/4 clutch is worn out.
Assuming you really only drove it 200 yards, is possible (likely?) that the trans was already well worn, and this was just the final straw.

Also, welcome to the forum!

 

I this not what I alluded to, suggesting the GOOGLE Search?

 

It is a brand new transmission

 

Brand new or not it was still run out of fluid. Mrvedit gave you same good advice on a simple test you could perform.

 

Well I unplugged the wiring harness and nothing changes at all. What would that mean?

 

When you say wont go past second, Do you mean second then neutral feel when 3rd should happen or just stays in second?

 

well when I take off, you can get in it and runs like a champ in first and will shift to second. Sometimes it doesn’t want to shift out of first. You can start going and then it will act like it’s in neutral kinda and you can ease off the gas and it will go into 2nd and sometimes you can hit tow haul and It will shift into 2nd and the harder you try to run it. It will start acting like it’s in neutral: you ease on the gas and slowly get going, you can get up to about 45 and high rpm’s. She will shift to second fine most of the time and others like I say, you have to play with it a little and it will not go past 2nd period. Either it’s running 45 and high rpm’s or acting like it’s in neutral!

there was no shavings in fluid, it was clean and didn’t smell burnt.

 

but yes it’s doing just like you just said.

 

I am gonna have to go with the 3-4 clutch is fried , The snap ring broke through drum something of that nature.
