Tranny life may be shortened due to a design flaw with the ATF dipstick/seal. The defect is it doesn't seal out moisture, and with it positioned below the passenger windshield washer nozzle, moisture can get in the fluid. So without periodic fluid changes, the tranny life may be shortened. On my '97 Bravada, I had the dipstick and the dipstick tube replaced under warranty at 24K last year. I also changed the ATF and filter at 30K miles, and replaced it with Mobil 1 ATF, since it has better heat tolerance than the std. Dex-III fluid. Incidentally, I periodically pull my boat with it, and live in a hilly region, so I think the tranny gets taxed more than a "normal" highway SUV, for example. No tranny problems, and the truck just turned 40K miles. Oh yes, my alternator and the belt tensioner developed a squealing bearing at 25K miles, so they were replaced under warranty. My '93 Grand Prix had an alternator let go electrically at 36K miles. My advice: if you own a GM, odds are good you'll replace an alternator at least once before 100K miles. Replace it with a remanufactured aftermarket (quality) alternator, NOT a GM re-man!

Thanks for your helpful input, poisondartfrog. I need to squeeze better than 200K miles out of my 1990. At 130K so far. I managed to get 120K out of the alternator and the tranny is still going strong (knock on wood). I change the fluid somewhat regularly, but I'll take your advice and try the Mobil 1. I'm going to push another six months on the front end, but it's shot. I need to do the whole works. The good thing is that the old models are easy to work on and parts are cheap. But if you can't do the work yourself, the Blazer is definitely a rather expensive truck to upkeep.
#6 of 511 tires & trannies by jetfixr2 Aug 08, 2000 (7:03 am)
If you put deep-tread knobbie tires on a Blazer (which I wouldn't recommend), would the resulting vibration tear up the trannie any more quickly than AT M+S tires? What's a good type for 50/50 paved road & gravel driving?

I'd be more worried about the bearings in the differential. I bet the crazy harmonics from the "knobby" tires on concrete/asphalt would accelerate bearing ball/race wear. I'd check www.tirerack.com for an AT tire (Michelin & Dunlop come to mind). You probably want the LT rather than the P series tire - gives you better load capability (stiffer sidewall) and 1 or 2 more plys.

#10 of 511 Re: Water in Tranny by poisondartfrog Aug 27, 2000 (4:31 am)
GM has a service bulletin about corrosion of the dipstick and corrosion of the dipstick tube. I had it on my '97 Bravada, which was fixed under the 3 yr./36K warranty. The fluid was also changed out (very iimportant). It seems the seal on the top of the dipstick is poorly designed; it allows water to get into the tube, and thus, the transmission. The source of the water can be from the passenger windshield washer nozzle/plumbing, or the water leaking past the nozzle seal. The trans dipstick is located right below! So it's two-fold - water drips into the tranny through the dipstick seal, and the rest of the water corrodes the outsie of the tube. Check the '97 Blazer forum for more instances of this problem. I would fight the warranty company on this one. As a design flaw, you shouldn't pay to replace the tranny.
#11 of 511 Recliner mechanisms by maggies285 Sep 22, 2000 (3:47 pm)
Bought Blazer new in 10-98. Recliner mechanisms replaced 3 times, and adjusted, and "cannot detect problem" another 5. Design problem per rep, potmetal used. Failure on 2 door blazers and x-cab Chevy s10. This vehicle has been a nightmare, 35k miles, idler arms, trim, short in instrument panel, more than I care to remember. Pages of dealer visits-must have been one of those Monday or Friday vehicles !
#12 of 511 bulb replacement by packman2 Sep 25, 2000 (9:55 am)
I own a 97,,,and all of the controls and switches seem to be lit up ,,,all but my headlight switch,,,does the switch cover come off? I didn't try to take it apart,,It looks that there might be a micro bulb behind it...also I have a question,,my tires seem to lose air pressure,,I might have bad valve stems,, or is it a problem with these aluminum rims...

I too, owned a 98 lemon blazer......it's not to late for you to file a lemon law claim! GM knows they produced alot of these bad blazers. I owned my 98 ZR2 for two years, 36 service visits, (generally unsuccessful service visits)....bad loaner vehicles, crappy treatment from reps at the 1-800, we have your money, we don't give a shit hotline( aka customer service). You don't have to live with the nightmare, although it took 2 years to return the lemon to GM,1GNCT18WXWK149605, I got my money back, recovered my attorney fees, and resumed a normal life instead of sitting at the dealership listening to lame excuses for my vehicle problems.
