Exclamation Hi I'm new - 1983 K5 Blazer diesel transmission question. HALP!

I bought a 1983 Chevy K5 Blazer (the one in my profile picture) and we just had it safetied yesterday. That was 600 bucks. And at teh mechanic's they said everything was fine, truck was running great. We drove it several hours, no problems, etc.

The thing is, I'm not well right now and I'm staying at my mom's in northwestern Ontario because I was able to get in to see her doctor faster and my husband was driving the truck and the kids + large dog up here to visit for a week or two while I'm getting treatments.

And tonight, on the freaking highway, the transmission fell apart. My husband said it's "all mushy inside." I don't really know what that means. But I figured someone here might. Right now, my family is basically stuck on the highway several hours from home and nowhere near where I am either.

My question is - how much is a transmission going to cost, roughly, including parts and labour? How fast can we get a rebuilt transmission? Does that differ in cost? How fast can we get a new transmission?

My husband doesn't want to stay in a hotel for several days with 3 kids and a dog waiting for the parts, you know? What a thing to happen. Argh.

Anyway, any help is really, really appreciated. Oh, the truck is originally from Arizona. It's been in Canada for 3 years. And has 31 000 miles on it. If that helps. Cheers.

Since no one else has replied, I will yet I may be of no help.

About 10 years back a 350 3 speed automatic would cost a minimum of $350 to rebuild in my part of the country, that would be labor and parts not counting removing and installing the transmission.

I would think its gone up since them plus from what I hear up in that part of the country it would be quite a bit higher. Maybe someone else will chime in that would be of more help. So sorry this came about at such a difficult time.

May the Lord Bless,

I had an 82 K5 with a 6.2 and a 700r4 automatic. About 10 years back it cost me $850 to have the transmission rebuilt and that was a real steal for all the newer heavy duty parts the guy put in it.

Those transmissions are notoriously weak. That was #2 self destruct on that one (1st time was just prior to the end of the warranty period) and I did not run it hard. I have several 700r4's and don't trust any of them. The one in my IROC has also been replaced (I do run that one pretty hard). The one in my 82 Z28 gave up the ghost as well. My 95 S10 Blazer is beginning to slip (newer version of the 700r4 called a 4L60E).

Those things are heavy as the dickens, too. Oh, about 6 years ago when my IROC transmission went out a local transmission repair place (AAMCO) quoted me $2000 to rebuild and reinstall the transmission. I bought a rebuilt one for $650 and put it in myself. I probably couldn't do it by myself now.

Good luck on yours. When everything is "right" they are sweet trucks. I never got mine stuck. Not at the beach, not in the mud, not in the snow. I pulled cars, trucks, SUVs even trucks pulling boats out of stuck spots easily (they are so heavy and the weight gives them good traction). Mine just beat me to death on parts replacements all the time. Just about everything broke at one time or another. Some of it multiple times.

abig84 will become famous soon enoughabig84 will become famous soon enough

the diesels came with a th400 (well at least all the ones i ever seen). i had mine rebuilt and beefed up a little bit for $440 at the local trans shop. so maybe a bit cheaper then that. but you have to pay for the removal and installation so who knows how many hours they will charge for that. good luck
