    We are thinking of buying a 1994 Jimmy with 100,000 miles on it from a family member. Does anyone have any thoughts on this year car and in your experience will it last a while longer or are we asking for trouble. Thanks in advance for your help.

    I have just paid $1300.00 for the replacement of the fuel injector assembly and fuel injectors on my 1997 4-wheel drive Jimmy. The truck only has 85,000 miles, and has been well cared for. Has anyone else had this problem and did I get took on the price?

    85,000 miles is about right for that unit. It isn't anything you did. It wasn't very durable. From other posts I've seen, they deteriorate on average between 60,000-100,000 miles.

    Good thing you got the valve body fixed,Poisondartfrog - or you would have ended up like joker1220. Joker, I believe you will find that you actually lost 2nd and reverse, and I'm guessing you heard a pop when it happened and a grinding noise when you accelerated which went away shortly. There is a part in your tranny that looks sort of like a 6" hole saw with a bevel cut gear shaft for a shank. That shank probably broke off. It is engaged by planetary gears for reverse and the drum potion is locked in for second. The whole tranny will have to come out. How do I know this? It was explained to me for only $1475.

    My father in-law has a 1998 Blazer LT 4 door that has a hard tranny shift from 1st to 2nd. It also seem hard into other gears, but 1 to 2 is the worst. He is off warranty. I saw Spoom post...I'm guessing that's what happens if you ignore it? Poisondartfrog, how much was the valve body job?

    Thanks,

    I have a '97 Blazer with a rusty transmission fill tube and some rust on the trans dipstick... Has anyone out there ever heard of this problem?? HELP!

    Also, does anyone know what the service requirements for Blazer transmissions are??? Has anyone ever had their trans serviced?

    Any info on this topic would be great!!!
  • Another GM design goof - either the windshield washer leaks water onto the dipstick, which has a lousy seal, allowing water into the tranny, or the seal at the base of the tube allows (rain) water in. Regardless, this is a re-occurring problem. The replacement cost as follows:

    Dipstick Tube - P/N 15735192, retail list $9.16
    Dipstick (Indicator) - P/N 15033544, retail list $5.44
    Seal - P/N 1259475, retail list $1.53.
    Labor - 2.8 hrs., or 181.50

    Including the 1 qt. of ATF, total cost $199.17 + tax.

    Note: the dealership did not change (flush) the tranny after this replacement. Since I didn't want rust particles trapped in the tranny or in the filter, I promptly changed the fluid/filter adterwards.

    There is a service bulletin for rusty dipstick:

    Service Bulletin Number: 990730004A
    Bulletin Sequence Number: 608
    Date of Bulletin: 9910
    NHTSA Item Number: SB6089191
    Make: OLDSMOBILE TRUCK
    Model: BRAVADA
    Year: 1997
    Component: EQUIPMENT:TRANSMISSION FLUID INDICATOR
    Summary: A CONDITION WITH A RUSTY TRANSMISSION FLUID LEVEL INDICATOR /
    TRANSMISSION OIL FILLER TUBE. *TT

    I service my transmission every 30K with Mobil 1 Synthetic ATF. The synthetic is more tolerant of high temperatures from high-speed driving, climbing hills, pulling a boat, etc. I have also added an external tranny cooler as additional insurance.
  • So I pulled out my Bravada repair file and prices are as follows:

    Valve Body: The GM replacement valve body is P/N 24217868, retail list is $476.30. You will receive a $50.00 credit as a core charge return for the old one. Labor was 1.8 hrs, or $129.60. With 11 qts. of ATF and a GM filter ($37.38!!!), the total outlay is $620.01 + tax.

    In addition, the slamming upshift caused the SES light to go on, which stored a P1870 code.
  • Don't ignore it! The slamming will beat up not only the tranny, but also the transfer case, U-joints, rear end, etc. Until I got to the dealership for the fix, I would move the shifter to '2' position at stops, which will start the truck out in 2nd gear, to avoid the harshest upshift (1>2). It somewhat kills the acceleration, but the slamming is not as abrupt.

    What does it take to service your transmission? Do you drain the old fluid by removing the transmission pan? Do you need any new seals to do the service correctly? How about a transmission filter... do Blazers have transmission filters that are easy to replace? What is the recommended service schedule for Blazer transmissions?

    Thank You for the info!!!
  • The service kit is no more than a new filter and pan gasket. I've used Fel-Pro brand available at Advance Auto Parts (about $12).

    Typically, to service the transmission you'd drop the pan to drain the fluid and replace the filter. To remove the pan, the gear change cable must be unbolted from the shift arm on the tranny, and then the cable must be disengaged (unclipped) from its bracket, and pulled back towards the rear of the vehicle to get access to the two 10 mm. socket head bolts holding the bracket and the pan. Remove the reminder of the pan bolts. The filter is accessible once the pan is removed. I clean the pan, including the square magnet (which is there to hold and trap small metal particles until it can be cleaned), and use gasket remover to get rid of any of the old pan gasket. Reverse the procedure for installation. Note: I find it a good idea to re-check the installation torque of the pan bolts after a week or two of driving; on the occasion I have a found a few had loosened up, but I re-torqued them and they were good to go.

    You'll remove 5-6 qts. of the total 11 qt. capacity, as the torque converter cannot be drained unless the tranny is flushed. A 30K maint. interval I believe is sufficient to renew the fluid properties, and is cheap insurance compared to replacing the transmission. Haven't had a tranny failure following this schedule on any of my past and present vehicles.

    GM states a fluid change every 100K miles for "normal" service.

    I just had the line replaced from the remote oil filter adapter to the engine, under a GM good faith repair (truck has 45k miles and no warranty left). I called the auto BBB to complain and GM contacted me. I was too late for the auto BBB (you have to be in manufacture warranty when you submit complaint), but GM offered to fix it anyway. I was shocked.


    I think we all should complain to NHTSA,

    This is a safety problem. If the hose breaks and engine locks up in a intersection someone could get killed. This may force a recall.

    Anyone else have problems with brake light fuse blowing? So far the we've taken the Jimmy to the dealer 2X to fix this problem. We've also had to take it back for transmission line leaks, finish pieces falling off, malfunctioning CD player, popping noise when we turn left....
  • Any chance you have the trailer tow package? If so, and you haven't connected the wire ends to a socket, the wires may be shorting against the frame... happened on my '97 Bravada, except the turn signal circuit would short out, which is also connected to the shift interlock switch. Now that was annoying. It would short out and then I couldn't shift out of Park!

    I've had intermittent problems with my wipers on my new 2001 Jimmy. After using the wipers when I turn the truck on the wiper will go half way up the window and stop. You can turn on the wipers and the function normally. Turn the wipers off again and they return half way up the window. If you turn the truck off then restart it, the wipers will return to normal. I thought it was strange but not a big deal. Then while using them the other day, they were going up and down then started only going up half way and back down. Then as strangely as it started that, it went away and started working again. Anyone else experience this? Any have a fix? My dealer just looks at me like I'm stupid.

    Thanks,

    Brian
  • Anyone have a clue? I've got a 2000 Blazer LT w/ 20,000 miles on it. When I make right hand trns, I get a major loud hum (and subtle vbration) This is much worse at highway speeds. Bringing it for service, but I want to be prepared. Could it be an "unbalanced drive-shaft."

    We bought a brand new loaded 2000 Blazer LT last May, loved it. By about July we couldn't figure out what was going on. Can't believe this is "normal" according to the 27 different service departments we've taken it into. After about 10-15 minutes of running the Blazer, an enormous amount of heat starts entering the passenger compartment, it just envelopes the entire cab, and I'm talking hot. We have the climate control system and they tell us to keep it turned on and set it for any temperature we want, that should take care of the problem. Give me a break here, what kind of fix is that? Talk about wasting gas...Is this a known problem with the 4300 Vortec engines? Anybody know of or have had this problem taken care of? Hate to drive this thing when it's above 75 degrees, we're talking nonstop air conditioning, not my idea of a good time.
