my tranny in my 89' silverado has somthing wrong with it! lol
aparently the last owner was driving along and when to gas the truck and there was NOTHING. the truck has sat sens that day, i picked the truck up for free seeing as they were moving out of state and it was going to a junk yard if i did not take it.

im asuming the clutch plates have gone bad. what would this run me up as far as money is consurned? i have about $250 saved at the moment and was wondering if this is enough for the plates what ever gaskets are needed ect.


its really not a bad truck for being free!!!!

If you do the rebuild yourself, you can buy a master overhaul kit and converter and have money left over. 350s and 400s are cheap to build.

If the trans is a 400 for sure, and it doesn't move in forward or reverse, I would try to replace the filter and fluid first. On the THM 400 trans it is common for the o-rings on the tube from the filter to the case to get hard and leak. This lets air into the pump inlet circuit and it will not pump air! The tube goes into a heavy rubber grommet at the filter and uses an o-ring at the case, I usually put two o-rings there to increase the seal. Sometimes the filter kit will come with two but if not just find a matching one to install.

This is a cheap repair to try before you go through the effort and expense of pulling the trans and overhauling.

Good luck,
Rick

oh well, the tranny is already pulled out, im only 15 and i dont have to much know-how on the situation, other then get a nice clean ply wood and take the nose peace off set it a side, next part next to the nose peace ect.

really right now i have $250 in cash and was wondering if i could get the clutch over hualed for this much or if i need to save my penneys, thanks for the repleys.

you have enough money, but first buy a video and watch it a couple of times. have some kind of a clue as to what you are looking at. you should be able to get a rebuild kit for under $150. step by step videos are available and easy to follow.

I would check the front pump first make sure its not busted. For a trans to be driving fine then poof not be then I would check the pump. Loss of pressure will act just like this. If it wouldn't go in any gear it wouldn't be clutches it would be pressure.

Go to your local trany shop and see what a carry out th400 goes for. Around here a 700r4 carry out goes for $550-750 and 400's around $350-450. If you dont no much about cars, much less tranys, then I wouldn't attempt rebuilding it yourself. You'll spend good money on parts, get it all put together just to find out it still doesn't work. Save a little more money and either buy a carry out or get someone that does tranys for a living to build it.

Get a guaranty that the trans is going to work if you do it there's no guaranty.

And he's 15, it's not like he could be driving it anytime soon, he's got plenty of time to do it. With help this website and a video he'll be fine.

Some of you guys had a good point, for the trans to just drop out during the ride wouldn't be clutch related, has to be something else.

i'll be 16 here in 3 months, and most people drive even without there licens up here, stupid, but we do it!


the tranny is already out and my moms b/f is a tranny specialist and he will help me work on it, i was just wondering what this could run me up.
now that im sure i will have enough money ill think of starting soon. thanks guys.

heck who knows i might end up being a tranny specialist too

[Ghetto Jet]

I just noticed your home state. If I lived up there I would be driving without my licenses too. Don't tell my dad but I put about 50 miles on my Caprice before I even had my permit or the car insured.

Good luck, keep us posted on it.

I Like learning the smart way not the hard way throught trial and error. I would agree that doing it your self is much more satisfying than just buying one but If you dont understand how it works your going to speed alot time and waste money until you get it right. Gets your moms B/F to help you go through it and maybe you'll get an education and get a working trans.

Just a bit of an update!

This tranny seemed to be on the back burner for a while and im just getting around to it.

i tore it apart about a month ago, only to find the person before me drove the living hell out of this tranny, the clutchs were gona and at least 2/3 of the rest of the tranny was JUNK! it must have been slipping for ever, looks as if there was enough friction to make it hot enough the oil tub melted and everything went cablummy from there

so i picked up a parts th400, an overhaul kit, shift kit oil filter torque convertor ect. ect.

and now all i need is a primary gear (which i can get for free from my mothers bf ) good to have a tranny guy around at times.

today he took all the parts from the parts 400 too work to have them cleaned, and to grab the other part from work. so by this weekend i should be re-assembling my transmission.

i never knew there was so little too a tranmission! only took me about 45 min my first time to take a tranny apart.

by this weekend i hope to have my silverado at his house so i can put the tranny back in it and put it up for sale any one need a truck? lol.
