just had my trans built. installed a PI 3800 converter. i had a transgo vaccum module installed, billet servos, high rev springs, all the bells and whistles. well anyways

i was testing the 1-2 shift under spin and next thing i know i heard a loud bang and now grinding and drive is gone have reverse but some noise. put it on lift and it will move rear wheels but not correctly. i can hold it in gear with brakes but speedo moves but nothing esle does and you hear a awful noise

im thinking plantery gears, input shaft or maybe converter

does this sound famliar to anyone who destroyed these trans? truck is about 4500lbs and in the neighborhood of mid 400s to the wheels in HP/TQ. spoke and said the man who built the trans and is known to be a good person and builder said he should stand by his product since it only had less then 100 miles on it.

 

i would take it back to him, might of had a defective part in it. The trans should have easily held together.

 

If your rear wheels are not moving but the speedo is that means that the output shaft is turning. I would be looking at the diff. Where does the noise come from?

 

that same thing happened to me in a sonama...and it was the rear planetaries...but if your speedo is working i would agree with flt

 

dropped trans today. first thing i did was drain it and i found metal chunks on the drain plug. also when i pulled the trans i was spining the converter and noticed i felt smooth then a harsh point then smooth then harsh again. along with that i heard a noise in there just spinning it by hand. also noticed before i dropped it i started it up in park and heard the noise also.



if its what you guys are saying whats a way to prevent this?

 

Hey, You broke your output shaft....after the speedo ring....but you'd think that would have fallen out when you pulled it...oh well just a thought....hope this helps ..Dave

 

so how does one go about fixing any issue like this. i dont want this to be a common issue

 

Install a billet output shaft.

 

so youre the tranny man?

so are you sure this is what happend? and how much is one of those shafts? what other things is going ot snap when i put this together

where od i get a billet shaft

 

PM sent.

 

First you gotta make sure the shaft is broken, then you gotta determine what the cause was ie, to much end play? too short drive shaft, bent drive shaft, ect. There are a host of problems that need to be addressed before you go sticking "billet" shafts in!!! Hope this helps ...Dave
