Is the motor holding back? Or dose it rev up just fine but not moving?

It revs fine just wont go. Past 25mph

Well you must know it is in the trany then, did you put one in from a junk yard?

Yea we took it from an exact model the truck we took it from had flipped and had 30k mikes on it

Well you'd think it would be good, Does it seem like it is slipping? Does the transmission shift? What is it doing?

Best Answer

It shifts to 2nd gear but after that nothing same as the old tranny

By chance was the old transmission removed and replaced for some reason before it had this trouble?

All i know is they drained the fluids and placed it in a warehouse thats about it i mean the tranny has 6 month insurance bur i just dont know where to look or what to do

A friend was saying it could be the cat converter but i mean the truck revs just wont go past 25mph

Well that was my very first thought, and now it makes sense since you had the same problem with the other trany...or not. You can check the cat by having the truck warmed up go for a ride in the dark, stop somewhere where it is dark with the motor running and look under neath at the cat and see if it is glowing orange. If so then it is plugged.
