    Tall jack stands for transmission removal from 2013 Escalade ESV

    Hi @skpyle! Minimum (for me) 24", to work comfortably 30"+/-, it seems like a lot but with wooden blocks it is an easily achievable height. Make sure you have a ratchet with straps at hand and remember that when you are putting your head under several tons of weight no safety measure is...

    Transmission Service? keep old fluid or put new..

    The new fluid will always have better conditions than a used one. However, if a transmission already has serious damage, new or old oil will not make a difference.

    Oil pan gasket replaced, still leaking... Might be rear main seal?

    ABS Sensor / Sluggish Transmission C0900 & C0899

    Oil isn't always the best indicator (unless you send it to a lab to find out what's floating around), your transmission may be at the death line and the oil still looks perfect: a stuck valve, a sprag about to break , a broken internal piston. Scan the transmission module and do basic tests on...

    2011 Tahoe LTZ/Evil Spirit Episode

    This usually happens when the BCM momentarily loses power while the vehicle is running. Check all the cables under the steering wheel and move them back and forth looking for anything loose. It could also be a cable rubbing against a metal part and causing a short to ground (I can't quite...

    Still leaks after 3 "fixes"

    I think my leak could reach that amount per day but I live in a very small city and I don't drive that much, here it's not even 20 miles from one point to another. That particular leak only occurs with the engine running. When the engine is off the oil goes down and doesn't leak through the bad...

    What is this line that leaks?

    My two cents, don't ask me why, use OEM tees and a pillow for your ribs :emotions34:

    Still leaks after 3 "fixes"

    Hi @solosys let me show you with photos and video where possibly your problem is. It happened to me and I almost went crazy looking for the source of that oil leak. To confirm if this is your case you can put paper towels behind the engine (top part between the block and the oil valley cover)...

    Has anyone run both the 'clean' and 'dirty' PCV lines into their catch can?

    Hello, that was me. My engine spit oil on the clean side under a high stress situation. Luckily it didn't happen again, now I have a catch can (open to air) in that hose.

    Can anyone help me find out what happened here?

    Hi huys, I'm back, the virus kept me away for a few days. Since the event occurred, it has not happened again (oil level OK), so I conclude that it was an excess of oil that was expelled. The truck is working perfectly, now that I'm fine again I'm going to rebuild the front suspension because...

    Can anyone help me find out what happened here?

    Oh no, I haven't figured it out lol, but it's the theory that most of us agree on, so far no confirmed source. The oil came from somewhere in the upper right area of the engine.

    Can anyone help me find out what happened here?

    Hi @hagar but if that were the case, the leak would be constant, however it has not happened again. I cleaned all that area and I have not seen any new oil leaks (and I use the truck every day). As others indicate, it was all about a pressure increase in the crankshaft and the oil came out of...

    Can anyone help me find out what happened here?

    @iamdub I am going to install a filter as you suggested, I have several floating around without use. @Joseph Garcia I do my own oil changes (mobil 1 full synthetic), the engine may have overfilled by about 1/4 of a oil quarter, that's roughly the amount expelled and what was missing when...

    Can anyone help me find out what happened here?

    Nope, my truck's air intake tube is a straight tube with a high flow filter at the end, it just has the MAF sensor and nothing else. That's why I don't understand where that oil came from, is it possible that it was returned by that crankshaft air inlet? It was not because of the oil cap...

    Can anyone help me find out what happened here?

    Hi @iamdub, no I don't have an oil cooler installed (that is why my post mentions that there is no engine oil circulating in the radiator area), the pipe you mention I have never been able to find where it should go connected.

    Can anyone help me find out what happened here?

    Hi TY forum members happy new year from Colombia, long story below: I have a 2007 Tahoe, stock 5.3 engine (I've only added an oil catch can and transmission radiator), 180,000 miles with all the maintenance routines. Four days ago I did a little 300 mile round trip (mixed road between flat and...

    After complete suspension replacement, crazy things started to happen

    My little contribution: Detroit axle ball joints and tie rods have a very, very bad reputation. I had a bad experience on the freeway years ago with this brand, then I did my research and it didn't just happen to me. The hit against the wall (no matter how small) could have misadjusted...

    2012 Yukon shudder/vibration around 1000 rpm and other quirks...

    Something similar happened to me once, the engine air intake tube was broken. I changed it and voila! Check out the cheap/easy-to-change parts first, then the more complex/expensive ones.

    2009 Tahoe stalls on ANY right turn - Solved & Thanks

    @torch thanks for the information, I live in a fairly rainy part, I am going to remove my module to seal it again, I prefer to have my mind at peace and avoid a now known problem.

    Dorman vs. OEM GM coolant "T's"

    I do not recommend either of the two, in my city I went to a metal shop where they made me bronze ones, no more coolant leaks since then.

    Serious Engine Oil Leak! Tahoe / 5.3 / 2007

    @swathdiver / @Geotrash thanks for your reply. My main suspect is the VLOM gasket (GM part # 89017690), I've personally checked: the rear main seal (looks dry, thank God), oil pressure sensor and valve cover gaskets, all dry. Apart from the pressure sensor my engine does not have any more...

    Serious Engine Oil Leak! Tahoe / 5.3 / 2007

    Hello TY Forum, while I wait for the parts to repair my transmission I decided to take advantage of my free time looking for a big oil leak in my Tahoe (2WD - street use only). I share this video with you, waiting for your comments on it. The leak is massive (1 qt in two days!). Tomorrow with...
