The automatic tranny in our '97 Blazer self-destructed at 110K miles, but I suspect it suffered from lack of fluid changes before we got it (sludge in the crankcase was evidence of maintenance lacking). That vehicle is gone - replaced with a '99 Cherokee.

Our '99 Blazer has 118K miles on it and has had regular tranny power flushes. I'm wondering what I can expect for longevity.

How far have YOU gone without needing to rebuild the automatic tranny in your Blazer?

 

124k so far. Reminds me, i need to change the fluid/filter.

 

178000 miles on my automatic on the 97 blazer. 212k on the 92 blazer

 

I have 310,000 kms on mine, so thats like 192,500 milesor so.

 

I got about 120,000 miles on my 99 blazer right now. It probably needed a tranny rebuilt about 10,000 miles ago. I'm going to make it last since I've only driven it for about 2,000 miles. I put the revised TCC injust to help it last longer.4L60E are one of the top ten most rebuilt transmission. yikes!

 

We have 121,000 onour 98 Blazer. It is due for a flush though.

 

79k

 

Some of this is very encouraging!

 

118k and still ticking...also due for a flush

 

116k so far. Ihad a little scare at 105k when I noticed a leak and I couldn't get reverse, but as soon as I drained the fluid and changed the filter it was all better. I'm not so sure about the flush thing...especially after 100k. I heard too many horror stories regarding failing trannies after a major flush. Or you can always talk about my good friend at work with a 98' that has needed three rebuilds so far. (86k) He got a used lemon of the lot and won't admit his mistake, so he'll just keep thowing money at it.
