The only thing this gearbox is driving, is me insane!... HELP!

[luciddreama]

/forums/images/graemlins/1zhelp.gif Hi everyone, I really need some help... This is my first post and I hope you are kind and gentle with me. I stumbled across your site and love it and you guys seem like gurus of all things 4x4!
I'm in the UK and there seems to be a distinct lack of info and help to be found quickly and reliably. I have a '73 Chevy K10 stepside with 4” body lift and a 12” suspension lift, 45” super swompers, I have just changed the manual box to a second hand 350 turbo auto box, (just for ease of driving on UK roads) and now we get to the point of this post. I fitted this box (huh that’s sounded so easy!) I thought I would try it without the prop shafts on just to see if the box would spin up… This seemed fine but after putting the props on and trying it there seemed to be no drive! Or not enough to move the truck. I can feel the box change from park, drive and reverse, but when revved there is no drive… And I know nothing about gearbox workings… Please help… I’m aware it could be a number of things but any suggestions would be gratefully received.

Thanks for your time.

Check your fluid level.

Hi there,
I started with an empty box and put about 2 gallons in then kept topping it up on the advice of someone that thought that same thing, but there was still no drive. Then I got a bit carried away and had to empty some out.

If it's full of fluid and not moving that tranny is junk. Pull it and have it rebuilt.

Is your transfer case in nuetral? That would explain how you "feel" the shifts but no drive. /forums/images/graemlins/dunno.gif

Ouch! Thats not good... but probably true... would you know of any good books to buy that would help me rebuild it in my garage?

 

[luciddreama]

Thanks good though but I have tried it in both high and low...

a th350 takes ~12 quarts to completely fill from a rebuild. was your rebuilt, or used?

if the level looks good, i would have to agree that it sounds like the transmission is no good.

just put the manual back in

You can also buy videos showing you step by step how to tear down and put back together...

Alot of the time when it moves but not very muck it may be just the pump in the front of the "box". However I had one that did the same thing and I had it rebuilt three times and its still sitting under the shed. After 9 times of pullin it and the 203 I went and found one out of a junkyard. Didn't change the fluid or torque converted until it rolled. Still working today 2 years later.
