Transmission Disorder
 

2001 Blazer 150k miles

First I would like to say I bought this knowing the trans was bad. I am not sure of too many details except that this is the second trans for this vehicle and it has about 75k miles on it.

I was going to use the car for parts but if I can fix it I will have a nice 4 wheel drive to use as a DD or whatever.

After I trailer-ed it home I tried to run it and after about 20 minutes it would loose all forward and rev movement.

I changed the fluid and filter.

The fluid did not have metal flakes in it and does not feel gritty. It does look kind of brown, kinda like clutch material.


This got the trans working again, but now there is a chatter/buck and some slipping when I get over 55mph at a steady cruise. I found a nice stretch of road to test this out. It does this in 3rd and 4th gear.

My guess is the 3-4 clutch pack is worn out.

Has anyone dared to go into the trans and rebuild? If so would you mind sharing your experience?

Thanks

i bought my 93 with the same issue, has all sorts of 3rd and 4th gear issues. since my truck is a off road only truck i just ignore those gears. 7 years later that trans is still working fine

I rebuilt mine myself not knowing anything about it. After searching youtube and other forums I had enough confidence to do it myself. Wasnt as hard as people think. The hardest part was getting it out. Took one day to rebuild and one day to reinstall. 7000 miles later its still going strong

Make sure you get a new torque converter built for it. i would never re-use the old one. It has as much if not more crud in it as the trans did. And flush the lines and cooler too.

That's cool, good to know these are tough transmissions. I really want this one to work correctly if possible.

Exactly what I wanted to hear, thank you. Glad it's still going strong. This gives me the confidence to take it on.

Yes I will definitely do this. I thought about reusing it as is but like you say all the old crap is still in there. I know of a place locally with a good reputation I can use.


Thank you everyone for your input.:icon_beerchug:

Update
 

OK so I'm a slow worker.

I decided the trans needs to come out and started the disassemble y. I removed as much as I could before removing the cross member. The stater was the hardest to get out, now I know how to do it, still a PIA but I found a little easier method.

A little more work and the trans will be out, and on to phase 2.

Glad your taking it on yourself. You can do it take your time

Thanks, will do. I'll update as I get more done.
