    700R4 Information Thread

    I think there's a diagram for the transmission's internal wiring harness in the 4L60 ATSG manual - I'll pull it down and take a photo to post in reply a little later today.

    TH400 Information Thread

    You're welcome - the below video should address all of your questions and then some - it's of my TH475 build up but otherwise is identical to how I'd build yours, other than maybe dual feeding the direct clutch (I didn't do that in the video) but it's very easy. Hot tank the case and all...

    TH400 Information Thread

    @DoubleDingo - Yank and overhaul the unit...Sounds like all of your applied elements are worn but will be important on tear down to determine if the wear is simply normal for the mileage and usage pattern or if there are other causes like hard part wear/damage...Inspect the lip seals, their...

    Performance 700r4 rebuild

    Does it say on the sticker on the case, when Hughes built that thing? Using a round hole rev input drum when the third design square hole was available would have been odd. I'm curious as to what valve body, accumulator mods were performed. Is this an aux valve body trans (87-93)? Were there...

    Performance 700r4 rebuild

    I see, looks good...none of all that was apparent in your prev post so figured i'd mention it, if you were just doing a refresh which is how I interpreted post #2... What are you doing for the 3-4 pack (dont say "Z-pack")?

    Performance 700r4 rebuild

    Replace the pump bushings, if you're not going to replace all of them. I like the Sonnax teflon coated rear stator bushing and their pump body bushing which can be used in the pump body and the reverse input drum (rear bushing). Also the input sprag - don't reuse the one that came out of it...

    700R4 Information Thread

    Let's start with what I asked you above: Did you do a pressure test to confirm/deny TV cable adjustment is correct? Nothing else matters until you have done a pressure test. Conduct the test and post your readings at idle min-TV and full-TV. Here's some instructions for doing the test, along...

    4L60E Information Thread (Includes 4L65/70/75)

    This is good information for folks looking to swap a 4L65/70/75E, as an alternative to a 4L80E, into a classic hot rod, resto-mod or other vehicle (Squarebody) with a built Gen 1 SBC or big block. Please update with the flex plate part number as that would complete the information chain needed...

    700R4 Information Thread

    When was this trans rebuilt? Is it still under warranty from the shop that built it? The no-OD and no L/U may be related. For whatever reason, if you don't wire up the lock up kit correctly, sometimes the trans won't shift into overdrive...See this occasionally in 200-4Rs as well. That said...

    Transmission Upgrade?

    Agree, I also like the visibility it brings to the transmission community (lol)

    4L60E Information Thread (Includes 4L65/70/75)

    I'd do it if you're racing/street-stip and the like...Keeps you in the power band and accelerating nicely during the 2nd gear shift vs bleeding so much of it going off before you finally recover before shifting into 3rd...As you said, the pain is all in the price but buy once, cry once...

    Take a pic of the metal disc then remove it - take another pic of what's behind it and post them both here. Assumimg you are looking at the governor and not the speedo housing bore, I'm curious to see what you're seeing.

    4L60E Information Thread (Includes 4L65/70/75)

    Lol, you'd be thinking wrong. I get what summit outlet is, it sells blems that aren't impactful to the functionality of the unit - I've done this a few times myself and beefed up the unit for whatever purpose or vehicle. What I'm saying is that you should have purchased a Gen1 SBC-compatible...

    4L60E Information Thread (Includes 4L65/70/75)

    Yes, lots of folks are suckers for good deals, and unfortunately, they are rarely actually good. All too many folks leap before they look when it comes to transmissions, simply because they don't know any better. I could have laid it all out for you insofar as what to do and how to build the...

    4L60E Information Thread (Includes 4L65/70/75)

    All that should work as long as you use the adaptor kit. The bells are deeper on the LSx Gen3 SBCs than they are on the 4L60Es that went in behind a Gen1 small block. You need a TMBX converter as well. Why did you buy a 4L60E for a gen3 small block? You could have saved a lot of money and...

    Too bad...hope you wont experience the cross leaks and premature applied element failures that are common with that rivited sandwich plate and/or experience a failure associated with their pressure relief mechanism. You could have accomplished everything that kit does and more for less than...

    4L80E Information Thread

    Starting a 4L80E information thread for those that want to learn more about this transmission (the best GM ever produced in my humble opinion), considering it for a resto-swap into a Squarebody truck or K5 Blazer (or anything for that matter) and/or considering taking on a rebuild of this...

    You didn't actually install that Transgo HD2 kit, did you?

    No idea until you provide more information like what transmission you have and why you think you need some sort of adaptor or spacer.

    700r4 speedo port not spinning at all.

    Maybe - not sure to be honest...You'll have to research that question or maybe someone else will respond to confirm/deny

    yep, those parts will work.

    700r4 speedo port not spinning at all.

    Little port thing? Lol, are you working on a boat? Kidding aside, simply remove the speedometer housing w/ driven gear and seal (dont lose the little retaining ring) then install the new driven gear, replace the seal if it hasnt been replaced already then bolt the assembly back in place in the...

    700R4 Information Thread

    Go to Pick-a-Parts and start looking at GM Squarbody trucks in the yard, particularly at the trans cross members and relationship to the frames. Maybe take one that looks 'correct' loose to see how it would sit/set up prior to being bolted back in place. What you're trying to determine is if...
