i have a auto th350..i think

its a 3speed right?

well second gear shifts very quick and low

like shifting from 3rd to 5th on a manual...it kinda boggs out

it shifts fine into 2nd...but kinda early into 3rd

whats wrong? just the clutches or so i need a rebuild?

thanks in advance!

Well, think about it like this. 3 speed needs to be up with a 4 or 5 speed... So, higher 1st and 2nd, but a low 3rd so you can get up to highway speed and have low RPMs. If 3rd were high up, then you would have high RPMs at highway speed and your gas milage would suck and your engine wouldn't last as long. Its just kinda how a 3 speed works. You're complaining now... go drop a powerglide in your ride and tell me about bogging down. lol

Uhhh yea whatever...

The TH350 is either going to have a 2.52 or 2.75 first and then a 1.52 second and always a 1:1 drive ratio. None of these steps are large. So it sounds to me like you may have a tranny shifting at the wrong RPM. Do you have a tach to tell what RPM the shifts are happening at? Also what rear end gears are you running?

But you never even said what truck you have so unless you did a V8 swap you don't have a TH350.
