#150 of 165 Re: Chevy Blazer 2002 - Interesting problem 4L60E [jlflemmons] by malutow May 22, 2008 (12:19 pm)
Replying to: jlflemmons (Feb 05, 2008 8:49 pm) I had a similar problem with my wife's Jimmy. I found the problem to be with the catalytic convertor. It would start to rattle when it warmed up causing too much back pressure. I changed it... no more tranny problem. However, that was last year sometime & I thougth i doged the bullet but I spent most of the day looking for a new tranny because reverse wnt out. Another common problem I guess. Good luck. Her truck is 1996 4wd Jimmy 4.3L.
#151 of 165 98 Blazer No reverse by bmpgbh Jun 21, 2008 (6:20 pm)
About a month ago i swamped my truck so it was off the road for a few weeks while i was doing repairs, any ways i didn't think to check the ATF and sure enough water had gotten into the trani. So about 2 weeks ago I was drivin up this really steep hill and when i stoped at a light and tried to go the trani would not go into gear. I waited about a 1/2 hour for the trani to cool then tried to go and it went just fine. so continued to go up the hill the trani got hot again and slipped. So i went home and change the ATF and filter the next day. Ran fine and shited the same for about a week, but just last week i went to put it in reverse and it wouldn't go. Any body have any ideas, solonoide or am i gonna need a complete rebuild.
#152 of 165 1995 S10 Blazer 4wd Tranny problem by blazeher Jun 23, 2008 (8:25 pm)
Please Help my 1995 blazer with no warning just started acting like it was in neutral, in all gears it wont move but the engine revs up, tried messing with 4wd to no avail. Turn it off and let it sit and it will drive about a block and do the same thing. Any ideas, is the tranny junk?

#154 of 165 Tranny Goes into Neutral by colink82 Jul 17, 2008 (5:02 pm)
Hey everyone, I have a 95 4WD blazer with transmission isssue's.   Shifts great up and down in every gear, but when doing freeway speeds in overdrive, if I give it a little gas it'll drop a gear easy, but give it a little to much gas and it goes into neutral and revs up. Remove my foot from the gas and it slams hard back into gear and everything seems fine afterwards. Tranny Fluid is fresh and is topped up, and was rebuilt about 50,000miles ago i'm thinkin maybe eletrical issue maybe? Replies to this message: jmccann (Jul 17, 2008 11:42 pm)

Replying to: colink82 (Jul 17, 2008 5:02 pm) I have a 93 Blazer with a similar problem that only happens in four wheel drive, it will go into a nodrive in any gear until I take it out of four wheel drive then I can put it back in four wheel and it will be fine again until the next time it happens, usually after a long downhill section or on a straight section when the engine isn't pushing it or a coast situation. The trans was just rebuilt the third time in two years and has less than 500 miles on it.
#156 of 165 4L60E question by jlflemmons Jul 19, 2008 (11:41 am)
On an '02 Blazer, 68K, 2wd   Transmission is downshifting too quick, and holding gear a bit long before shifting. No other problems, just acts like it is mis-reading the speed and load. All shifts are good, drops right into gear, both forward and reverse, no weird noises. Tranny was serviced about 5K ago, no trash in the pan, no burned fluid, all looks good.   I guess the best way to describe what it is doing is it acts like it is in tow-haul mode, even though that isn't an option on this vehicle.   Now, I should point out that this is a Blazer xTreme, and has had the ECM flashed to factory specs. I am told that the xTreme does have different operating parameters than a standard Blazer since it has a lowered suspension, handling package, and high speed rated tires. We also have a '99 standard Blazer, and the drive train definitely behaves more sedately. xTreme editions are very rare in the part of the country, so I cannot find one to compare it to.   Thoughts?

Replying to: bdp68 (Jul 28, 2008 5:50 pm) I had an 87 Camaro with the 700r4 transmission that had a similar problem that turned out to be the governor that is under a cover on the rear side of the transmission, I grabbed another one out of a junk yard transmission and it went back to working normally, pulling the governor is simple, remove the cover and pull out the governor, push the new one in, replace the cover and get in and drive, very simple job.
#159 of 165 98 Blazer tansmission fluid level/leak by kruz Jul 30, 2008 (1:09 pm)
I recently bought a 1998 Blazer that hadn't been run in 2.5 years. I got it running quite easily and checked the tranny fluid level when the engine was cold and it registered way above full/hot. I took it for a test ride to get the fluid hot and rechecked the fluid. It didn't even register on the dip stick. I added almost 3 quarts of tranny fluid and got the level up to where it should be with a hot engine. I ran it for a couple of weeks and started noticing tranny fluid puddles after everytime I drove it. The leak isn't coming from the transmission area but from somewhere in the front of the engine compartment. There's a plastic shroud under the front of the engine/radiator that restricts me from seeing the source of the leak. I recently rechecked the tranny fluid while hot and it's barely registering at all on the dip stick but when the engine is cold the fluid level shows over full. Where do I start?
