    Is this a crazy idea to cool my 4L60E transmission?

    The job is done! Tomorrow night I'll go out and drive around a bit, although I won't be towing anything for now. Sorry if my question caused a bit of tension here. PS: The thermostat was in terrible condition and I think it was the cause of the leaking radiator (increased pressure in the...

    Is this a crazy idea to cool my 4L60E transmission?

    Thank you all for your good advice, forgot to mention that I have an external radiator too, I will do the experiment next week; if it doesn't work or I'm not convinced I'll just plug it in as it was.

    Is this a crazy idea to cool my 4L60E transmission?

    Hi TYForum friends, I am changing my Tahoe (07 stock Tahoe, 5.3, 4L60E) stock radiator because it's leaking like crazy, when I saw the new radiator I had this idea: Since I don't use the engine oil cooler, can I bridge the lines on both sides to form a larger cooling circuit for my 4L60E? I...

    2013 Tahoe - Stabilitrak issue

    Hi! Some of my tips to deal with this message: Check your fuses. Check your grounds, run a complementary temp. ground from your battery to the engine block and drive your car. Wiggle your BCM harness and see what happens. Many times it is a shorted module that blocks the CAN network what causes...

    4L60E No reverse - Wear gloves to handle this post

    Yes, everything is taking shape again, the smart shell looks solid let's see how it behaves. I tested the input drum with air, no leaks. I saw a video of someone suggesting trying it hot but the idea of heating it in oil doesn't seem safe to me. Working on these transmission is relaxing and...

    4L60E No reverse - Wear gloves to handle this post

    Hi @NickTransmissions, what an amazing answer, thank you very much for your time. I also thought the same about the converter but I saw it open and it was fine, anyway I'm installing a reman. converter. All my suspicions are on the valve body and the EPC. In the new valve body I included all...

    4L60E No reverse - Wear gloves to handle this post

    Hey @Just Fishing, thanks for answering! It's been a few days now and I've been a bit busy to finish my journey with this transmission but I have been able to reach several conclusions: The manual valve was causing a leak in the P/R circuit EPC solenoid failed causing low pressure The...

    No engine light, old codes P0700 P0741 P0742, transmission seems to shift perfectly smooth, no shuddering??? 2013 Suburban Z71

    Proceed with caution: sometimes those codes you mention (P0700 P0741 P0742) don't turn on the check engine light. My transmission died with check engine light OFF, codes found before remove it from my truck: P0741, P0745.

    Greetings and another oil leak post

    You seem to have covered almost all the possible scenarios, I think it's time to use fluorescent ink. There are leaks that are not visible while there is no oil pressure, the rear main seal is a very problematic area, many times it can appear "dry" because the turbulence generated by the...

    Erratic intermittent no crank no start

    Hey @Denali207, my humble advice: 1. Try a new battery and another programmed key. 2. Check your battery cables and make a voltage drop test (remember that a battery cable can look perfect on the outside, including the terminal, but be rotten on the inside.) 3. Check your grounds, specifically...

    Help, No power to vehicle despite good battery and power to fuse block

    @Adam Jinks if you have basic knowledge of electricity bypass your main battery cables, take two jumper cables (a good quality ones) and connect the negative directly to the negative of the engine block and the positive to the mega fuse (or to the fuse box directly). It may seem like a simple...

    What is the best way to seal aftermarket head lights?

    Hello, butyl sealant tape this is the best sealing method I have found so far. However, keep in mind that all lights must have a breathing hole for condensation to escape through, usually a circular hole covered with a black membrane. There are NO vacuum sealed lamps o_O Product...

    Tall jack stands for transmission removal from 2013 Escalade ESV

    My grandpa method may seem a bit strange but it works, you can drop or install the transmission without needing to be completely under the vehicle (this is my favorite part) using a pair of two-way ratchet straps, a jack and wood can be useful to gain stability. To use this method you cross each...
