89 K-5 with a tranny/transfer case problem

My Blazer developed a leak in the transmission. I took it to a transmission shop to have it serviced. He told me that the transfer case was coming off and that is where my leak was coming from. I told him that I couldn't afford the work to be done on the transfer case. So he checked out my transmission and said that it needs to be rebuilt ($2500). It's making a buzzing sound. I can't afford a tranny right now so, i was going to change the seal on the transfer case and try to stop the leak. The tranny isn't showing any signs of slipping at this point. When it does I will look for a used transmission. He told me that I had to find an 89 transmission. Is that true? is that the only type of tranny that would match? Any advice on this situation would be helpful! Money is tight as we all know! Thanks in advance!

Which transmission?
What engine?
Was it serviced?
Where is the leak?

Several different years should work.
There was major changes around 86 and 93 electronic shifting transmission was started.

Different years and engines and transmission the lockup wiring circuits may be different but they can be rewired to work.

2500$ sounds a little high for a rebuild.
I would get a second opinion on your problems.

Re: 89 K-5 with a tranny/transfer case problem

I have an automatic transmission with a 5.7 liter engine. 4 wheel drive full size blazer. They did the tranny service and he said that the tranny needs to be rebuilt. He changed the filter and added new fluid. He said the main leak was coming from the transfer case. He said to re-seal the transfer case would be around six hundred but, he told me not to bother doing it because that would be part of the rebuild. I figure I should try to stop that leak until the tranny is showing signs of going out. What do you think? Thank you for your reply!!

Re: 89 K-5 with a tranny/transfer case problem

I do have a buzzing noise, almost sounds like a heater fan sound. The sound is present after I start it. I really don't know what kind of buzzing sound I'm listening for. I don't think the transmission itself is leaking, it looks like its coming from where the transfer case and transmission meet or where the transfer case adapter meets with the transmission. The shift from first to second is at about 15 mph, kind of thrusts forward when it shifts and from second to third around 31 mph. I don't think I have ever gone beyond that cause I just drive around town and the mph around town is 35. I'm not sure what type of transmission it is. The person I bought it from told me he rebuilt it and then didn't tell me much more. This is learning truck for me, I don't know a heck of alot about mechanics. Thanks again for your help!

PULL THE TANSMISSION OIL PAN AND CHECK FILTER AND LOOK FOR ANY METAL OR EXTRA PARTS OR EXTRA CLUTH MATERIAL AND CUT OPEN FILTER AND LOOK IN THERE TO.
TELL US WHAT YOU FIND THERE.

On the leak between transfer case look for cracks there and loose bolts.
Get a eye on right where it is leaking.
Tell us what all you see.
