Transmission shifting problems
When I take off in drive the seems to hang between gears and engine will race. I can
slow down and manually shift into the right gear and it will start shifting properly. This this
does not happen every time I start off from stop.
Sounds like the solenoids are getting sticky inside the tranny, you can try servicing it, putting a quart of TransX and then fill to specs and drive as you normally do, this will help cleaning the solenoids, if it is going to work it will in the next day or two, if things don't change then you will have to replace the solenoids. Eventually you will have to replace them.
Thanks for the info took car to transmission shop. It was checked out and turned out to be selenoids.
Glad you got right on this and fixed it, so many just want to get by as long as they can.
needs some help by any chance do u know why my tranny didnt work after i change both solenoids
H, did you have codes for the solenoids? Or was it trans control codes?

What you are describing sounds like an intermittent ground problem, unfortunately there are a mess of grounds on this rig, both inside and under the hood, if you want to attempt this I would advise you to get a good shop manual with wiring diagrams and component locator, then grab your wire brush, emery paper and start cleaning the grounds. HTH
wat is hth and thanks for ur answers appropriate it alot ill try that but would it efect if i put a ground wire directly to the black ground wire on the sensor just to see if anything changes and so do u think the pcm modual or computer i guess is the same thing but could it be damaged
HTH is hope this helps. You have to be very careful running ground wires, you can do that but make sure you only use the main grounding mounts, not just a sensor ground wire, you can also run separate ground to each of the points you find from a reliable grounding point, but make sure you have a ground and not a sensing wire or power feed, 12 or 5 volts, or it will cause expensive damage. You might also check the contacts on the back of the instrument cluster and the cluster grounds. I know this sounds involved but it really isn't if you have the connection points in the shop manual it reduces time involved and you can trace out each circuit.
ok thanks very much for ur help ill try and run only one ground wire from the sensor to a grounding point and i will definitely not try to power feed to any sensor that could effect my vehicle just one ground i will run thanks again and have a wonderful evening

I have a 1995 s10 blazer and it would appear that the same problem has been apparent since this blazer if not before, and up and to the current models and I cannot believe they have not corrected this yet!!! , or even at least to all of your helpful comments Up an 'till the 2006 model yr. Scott~LittleRiverSC.
Like I said above, I have a 1995 s10 4x4 4dr blazer w/212k on it. I was told to put Lucas in the tranny, so that's what I did with NO resolution to the shifting problems!! I only drive it to the grocery store once a month, but I either need a quick short term fix so I can sell it or I need to resurrect it for another 30-50k. Any help would be greatly appreciated !! Is this blazer even worth keeping or should I just try to sell it as is? Thanks again for your help Scott~LittleRiverSC. Eightsixzero nineeighttwo seventhreefourtwo
hi i have an 07 trailblazer ss when i put it in reverse it doesnt move i can put it in drive and it goes but no reverse any ideas on how to fix thanks
Sorry Anthony, I haven't received any answers to my transmission issues either. Now my blazer is dead in the driveway. Best of luck to you. Scott
2007 Trailblazer Not shifting in to the 3rd gear... (slipping) Lucas mechanic in a bottle did dick. Hope it's an easy fix because I bought am older car to safe money. Shit.
If it is slipping it most likely needs overhauled, if the trans fluid is dark and smells burnt that is a sure sign of a trans in need of a overhaul.
Which is expensive right? ... It actually was most our of fluid yesterday and I dumped in a bottle if Lucas and a quart of transmission fluid. I have driven 10-15 miles since I did that but only Reverse, 1st, 2nd work like it is supposed to. In drive it takes off normal but once you get to 50mph or so rather than shifting down it revs up. It is over full now by the way...
Yep, between 800 and 1000 bucks in my area, I have heard of some people that have drove through that they have paid as high as 2 grand, I guess it all depends on your area.
Anthony, your transmission likely blew out it's sun gear housing. This is a common problem on the 4l60E transmissions. If the housing did blow out, you will also not have second gear, resulting in a hard shift from first to third.

I need help with my 01 chevy blazer 4x4 there is a leak in the tranny someware up front and possibly the mid section of the tranny ot at least thats ware the leaks are commin thru on the tranny cover
Dear brother i hope that u can help me to find out the problem in my chevy trail blazer 2008 ,Last year, August 2016 I change the 4W drive case and become little better for a year and recently, I encountered same problem when shifting to 2nd gear looks like there is car hitting from the back. This is after the car was stock on the sand beach and we force the car to move by changing the 2W, 4W up and 4W down switch for half an hour. Then it happens also in 3rd gear but lighter than the hit on 2nd gear. The rpm gauge was playing also from 3 to 4 when we were driving going up off road looks like the gear is having a hard time shifting or not shifting at all. Then, when I rest the car the following day, sounds better but starting to hit again on 2nd gear after staying the car open and long drive approximately 80 kms. It starts shaking when its shifting and after awhile its start to be stronger then to hit/pump again like car hitting from the back. Whenever the car will rest long time it will be okay but when you start to use it for driving the car will start again to be like that. And when I stop the car and go under if you shift between D-R you can hear sound like jangle. god bless u am hisham
I have a 2003 trailblazer in when it get into 2 gear it want go over 20 miles
Hey Guys I have a 2004 Chevy Trailblazer EXT 4wd LT The trans starts slipping in overdrive about 50 mph mostly going uphill or under load.There are different clutch packs for each set of gears.The most common problem is the pack for 3rd to overdrive will start to slip and then fail.I screwed up by not having my traqns serviced every 50,000 mi.,so I would start by taking yours to a good trans shop for a filter and fluid flush and refill with good ATF. Good Luck
