1995 Transmission Power Purge

I have 145K on my blazer and I am looking to get the transmission serviced. From my recollection, I have never had the tranny serviced. I took it to AAMCO one day looking to have it serviced. They told me they would power purge the system. After they found out how old it was and that I have never had the system serviced, they called me later after their "test" drive and advised me that they needed to drop the pan to take a peek. Additionally they said they would need to rebuild the transmission and that is was going to cost me $1600 bucks to do so. I declined!! I just want to get the thing serviced? Are they trying to take me for a ride? The tranny doesn't slip and I don't pull trailers with it at all? Also, what is the difference b/w the full 15 quart power purge process versus changing the filters and the fluid from the pan? Not sure what I should do. Would disturbing the tranny at this point cause any problems? Looking for some advice on what I should do.

haha 1600, u got off easy, i took my 97 w/ 99,000 at the time to AAMCO, they wanted 2,300 to do mine. My problem was it was shifting very hard in to 2nd gear. They said i need a full rebuild. I ended up taking it to my uncle who does trannys we found out that someone drilled the valve body spacer to make it shift that hard, the trany it self must of only have 10,000 on it all the clutches and stuff were brand new. I would get a 2nd opion from someone else

A lot of trans shops are trans rebuild happie.
Watch out for the chain stores They are the worst.
If it is running good get it serviced.
And do not fall for that power plurge stuff.
Bunch of crap there is no such thing.
It is just a trans flush or total fluid exchange.
You can flush it or just change the filter and fluid.
And flush it with another filter change a little later.
If you flush it make sure you change the filter with the flush.

This is the classic question, should you do a full flush on a tranny that has had no regular service. Its a gamble, you could be just fine, or... In my opinion, I would drop the pan, change gasket and filter, and refill, run that for a while(not too long), and then I would flush the whole system and again, filter and gasket. This way your allowing some new oil in the system to start the cleaning process in the tranny, the new filter will collect the sediment, and at this point flush the whole thing, with a new filter installed again. At this point hopefully most of the large sediment is removed, and your good to go with the flush. Doing a full flush right away "could" not always, but could dislodge enough sediment that it could cause problems with your transmission. Thats why it is important to service your tranny regularly, so you won't run into problems like this.

Or you could do nothing. I have 237k on my s-10. Never had the trans serviced. Runs like a champ.

YMMV. :)

Yeah... because you know, that transmission servicing stuff is just like... the MAN trying to get your hard earned money?

I won't ever understand why someone would neglect their transmission but not their spark plugs. Both are fairly inexpensive, both not too difficult (though the tranny can be a bit messy), and they both are protection on your INVESTMENT.

I went to Level10 to get my trans flushed and the service guy said to avoid the flush, just drop the pan and change the filter and oil. he said the flushes cause nothing but problems

If you want to be REALLY thorough your best bet is to change the gasket/filter, clean the magnet or throw a new one in, drive for a few, get the flush done, and change the filter again.

Personally I think changing the filter and cleaning/replacing the magnet is sufficient. I know you don't get ALL the fluid, but you get a lot.

I have 190,000miles on my "94" Blazer. I have service the trans every 50K miles (filter, gasket, & fluid). Never flushed it. I have never had any trouble with my trans. My feelings is as long as you take care of your trans and services regular. You should have any problems. Of course unless your racing it.

If GM had made things a bit easier with regards to changing the filter and gasket on these Blazers, I think it would be a no brainer to simply change the fluid and filter and skip the flush.

I've determined it is all int he "Y" pipe on the engine. My previous 1994 Blazer allowed me to simply remove the crossmember to do the filter and fluid change. My 93 requires me to not only remove the cross member, but unbolt the Y pipe as well, (duanting task until I realize the nuts and/or studs were actually coming out for me). I haven't done my 95 yet, but I'm thinking the Y pipe isn't going to be in the way on this on either as it appears to allow a little more room (hope hope).

i have a 95 2door, i wound up dropping the t case skid plate and the crossmember and was able to slip it past the y pipe

If you can't get it past the pipe, all you have to do is throw a jack under the transfer case and jack it up. That changes the angle of the tranny to the y-pipe and gives you the clearence, no need to disconnect the y-pipe.
