    TH350 To a 700r4 transmission

    Thank you, Rob. I actually haven't torn down one of their units and don't know too much about them other than they are among the many larger-scale performance transmission builders. You should take pics at each stage of the tear down and start a thread showing the tear down and reassembly -...

    TH350 To a 700r4 transmission

    Nope, you're correct. ETA: I'll film and publish a vid on pressure testing at the earliest opportunity as it's really applicable to all transmissions though mandatory for the TV-based units like the 700R4 and 200-4R to confirm TV cable set up and adj.

    TH350 To a 700r4 transmission

    Fair enough - it seemed as though you may have been questioning my commitment to customers & standing behind my work so wanted to address it in case anyone else had the same interpretation. I'm not trying to talk any sort of game or use this or any other website to grow my business so hope...

    TH350 To a 700r4 transmission

    No one is perfect however I do stand by my work 100%...Please don't correlate my tenure here (or any other forum or the age of my YT channel) with my time on transmissions, esp the 700R4/4L60E. I taught myself how to build them over 10 years ago because I got ripped off by a transmission shop...

    TH350 To a 700r4 transmission

    How much is Monster charging and what are you getting for it? You gave them all of your "specs" - did they give you theirs for their trans? The swap itself is straightforward. You'll need to move your x member back a bit, cut and rebalance your driveline and make sure to set up and adjust the...

    ‘86 C10 700R4 pan leak with new gasket

    To @Ricko1966 's point, verify that it is the pan that's leaking. If it's the front pump seal, simply yank the unit and replace the seal - put assembly lube or peteoleum jelly on the new seal before installation and trans fluid on the converter hub. $43 on a friggin pan gasket is a complete...

    700R4 wont shift into 3rd

    Neutral condition at the 2-3 shift is burnt 3-4 clutch pack. Time to pull it for overhaul. You can always drop the pan to be sure but if it went from shifting through all its gears normally to neutral in third (assuming you still have 1st and 2nd and no tv cable issues), trans is done. Check...

    700R4 Information Thread

    The main killers of gears, esp planetaries is heat, lube starvation and/or aged/contaminated fluid so if you keep up with fluid changes, ensure fluid levels are always where they need to be, your circulation has no obstructions or restrictions and temps are 175-180 max on a continual basis...

    Keep Manual shift for the LS or swap in an auto?

    Agree 100% It takes a metric ton of effort (upgrades, updates, corrective measures) to get a 6L80 to anywhere near as capable as a 4L80E in terms of durability/reliability, IMO. To All contemplating an auto swap and considering one of those two transmissions: Here's my short 4L80E list of...

    Keep Manual shift for the LS or swap in an auto?

    There is no universe where the 6L80 is stronger and more reliable than the 4L80E.

    VSS question for a 4wd with a 0411 pcm.

    If you're swapping in a 4L80E that has two speed sensors and it's a 1994+ unit then you're working with a 2WD 4L80E. The 4L80E had both speed sensors on the transmission for both 2WD and 4WD applications from 1991-93. However, starting in 1994 they moved the VSS (rear speed sensor on the...

    rusted drum

    If the rust is just on the outside portion of the housing and is superficial, just sand it off. If its inside, will need to see a pic to know if it's something I'd try to fix or not. Worst case, just go grab another forward drum assembly from your local hard parts supply shop or grab one from...

    Shift shaft seal leaking on 700r4?

    Its easy. If you have done it before, it will be just like riding a bike again in that once you get started it will all come back to you. When you go back to re-stab it, you must ensure the converter doesnt drift forward on you - that's the biggest risk point you'll face. The second area of...

    Shift shaft seal leaking on 700r4?

    Do it yourself and you wont have to worry about it. And no, there's no reason it would be leaking beyond a worn seal or worn shaft. The seal is a dollar and shaft two to five dollars. Its a easy job and takes only an hour, assuming you drop the pan to do it.

    transmission id number 17-cl-43491

    Are you using "talk to text"? As far as the numbers are concerned, one represents the year while the other is a serial. Please quote this post when you reply otherwise i wont be notified.

    transmission id number 17-cl-43491

    If the two big letters on the ID tag are CL that's a TH400 out of a GMC school bus from 1973 or a TH475 from 74-80; The TH475 is identical in appaearance to a TH400 however has straight cut gear sets and, I believe, a heavy duty direct clutch pack (6 frictions) in the drum. Highly sought after...

    TH400 drive off and shift problems/weird acting

    Good callout on the line and cooler flushing - both must be flushed before reinstalling the trans after overhaul. I always advise doing burnouts in manual low to ensure you have as many applied elements involved to spread the stress out so no one clutch pack or band suffers.

    TH400 drive off and shift problems/weird acting

    How many miles on the trans? Any recent work done to it? Delayed engagements, "hunting" usually indicates burnt clutch packs...Sounds like it needs an overhaul. First check fluid level if you haven't already and smell it. If it smells burnt, drop the pan to see what's at the bottom. Lots of...

    Is there a single prong Lock up switch?

    Nope, that's the vacuum modulator. Not a solenoid. Your pan looks like this? This is a TH350 Pan. This is a TH400 Pan I'm 100% positive those pictures show a TH400.

    What transmission do I have?

    You're welcome, walleye. Can't think of anything other than what I've already listed above. Start with the cable adjustment and pressure test. If it passes, take on a road test to see what happens. If you still habe no 3-4 upshift, its either governor (not likely but possible), valve body or...

    What transmission do I have?

    No 3-4 upshift is somewhat common on earlier 700r4s w/first design valve bodies. Several times I have had to swap the vb two or three times before Id get one that fully works. That said, a few common causes: 1) Worn 3-4 upshift valve 2) 3-4 Relay valve installed backwards 3) TV cable slightly...

    Torque Converter Recommendation

    If Blueprint is recommending a 2200-2400 stall, why are you questioning that?
  24. NickTransmissions

    What transmission do I have?

    No upshift (you remain in third gear) or does it shift and you feel like its in neutral?

    Cracks in transmission by output shaft

    Not cracks; just normal byproduct of the casting process.
