    transmission oil change

    Ditto what @Ricko1966 said; check Mr Gasket for a rubberized gasket with steel inserts, think they make one for the TH350. If you cant find it, composite gaskets are fine but DO NOT use cork or regular rubber as they both leak. Fluid is your choice. Trans fluid is heavily regulated so any...

    700R4 Information Thread

    Didn't watch the video but your description seems to indicate either governor, 2nd gear servo or valve body issues (perhaps 1-2 throttle and/or shift valve sticking), if it's the transmission (still don't know whether you've tested and ruled out engine-related causes). The sizable RPM drop from...

    Yes - I'm referring to any dipstick/dipstick tube that may have been in whatever transmission was already in the vehicle prior to the 4L60E swap...In other words, discard the former transmission's dipstick/tube and install a 4L60E dipstick tube in the 4L60E that you or whomever swapped into the...

    700R4 Information Thread

    The stack-shifting can be due to improper set up, mal-adjusted TV cable or incorrect TV cable geometry (not saying that was the case with yours but those are common reasons for stack-shifting)...Other reasons include wear/cross-leaks in the forward drum's apply circuits, weak pump, worn TV boost...

    Just curious, do you not trust the trans shop? To your question: It should work, as the case architecture in the area of the distick tube location is the same through all years 700R4 and 4L60E.

    700R4 Information Thread

    What year 700r4? Only the 1982-E87 in some models had the TC lock up in 2nd gear...Plus the TCC wouldn't drop RPMS that drastically...More than likely, there's a partial tie-up during the 2-3 shift due to the band not releasing completely before the 3-4 clutch pack applies. This happens when...

    700R4 Information Thread

    You're welcome and sure...Have you ever been in a 700R4 or 4L60E where the 3-4 clutch has burnt up? If so, when the transmission shifts from 2nd gear to 3rd gear, it will feel like it's in neutral...But it's not actually in neutral - it's simply back in first gear...In third gear on these...

    It shouldn't hurt the transmission but wouldn't go too far beyond that as you'll start to feel as though you're in neutral, if so.

    4L80e 1987 C 10 ls swap not shifting

    If no power is getting to the trans, he will start out and remain in 2nd gear...If it's a speed sensor problem, he will start out and remain in first gear...So the purpose of the test is to see via process of elimination what gear he is actually in when everything is plugged into the...

    4L80e 1987 C 10 ls swap not shifting

    You need to determine if you have a vss problem or whether you're in limp mode due to a failed/shorted solenoid or short/problem somewhere upstream of the transmission. So follow the procedure i specified above and let me know if the trans feels like it's in the same gear as when it's plugged in...

    4L80e 1987 C 10 ls swap not shifting

    What is the "stand alone harness" connected to? Unplug the large connector on the driver's side of the transmission, get in, fire it up and put it in Drive. If it feels different then you're in second gear when plugged in which means limp mode. If it feels different (i.e like its in a deeper...

    4L80e 1987 C 10 ls swap not shifting

    Is the transmission stuck in first gear or 2nd gear?

    4L80e 1987 C 10 ls swap not shifting

    Sounds like either it's in limp mode or no vss data is being received...What's the deal with the transmission? Is it a fresh rebuild or used? What are you using to control the transmission?

    115 is fine, basically as long as it's functioning as it should, your temp is good, as far as the low side is concerned...I don't like to see anything higher than 175-185 on the high side for the Powerglides, three and four speeds...The six speeds can be as high as 200* or so as they were...

    1984 k10 700r4 won't shift out of 2nd please help!

    Glad it will be getting rebuilt. The vette servo wasn't partially installed, it only applies to 2nd gear. 4th gear uses an additional piston inside that servo cover, which is the same across all 700R4s and 4L60Es (there's aftermarket billet servo assemblies available for both 2nd and 4th gear)...

    Transmission ID

    Colors are irrelevant...Using TCIs speedo calculator, you need to plug in your tire diameter, final drive ratio and drive gear tooth count to determine the tooth count for the driven gear. This will get you close to spot on. There should be a number in front of the "CK223....). That number...

    Buy the Superior Tech governor kit. Should have what you need to adapt your gov for diesel

    700R4 Information Thread

    Governor is the primary difference. The valve bodies themselves are the same between gas and diesel applications...200-4Rs by contrast, use different governors, valve bodies and 1-2 accumulator housings (in case anyone was wondering, lol).

    700R4 Information Thread

    I actually set one up for a 200-4R recently so the 700R4 isn't all that different and I imagine will involve the same or very similar steps.

    700R4 Information Thread

    I imagine that could be possible, if you wanted to either make different size restrictors to achieve a certain pressure 'floor' which can be adjusted by either swapping out different restrictors or making an 'adjustable' restrictor...You'll have experiment and test...I'll look into it also and...

    You basically have to block the TV Boost valve so it's wide open and same with the TV limit valve. You also need to modify the reverse boost valve to avoid a severe overpressure condition when in Reverse. I think I have some instructions Chris at CK gave me a few years ago so if I can dig them...
