    Thanks Nick your the man! We got a good rebuild kit from summit and some of the rubber rings looks like they might be the right size but I’ll check tomorrow to see if they fit. Here’s the one we got: https://www.summitracing.com/parts/SUM-705021

    Transgo kit 1&2 vs SK 400

    Yessir. 454 with mild roller cam and 1600 hughs towing stall converter. No dual feed. In regards to the 2-3 piston, we got a new aluminum one to replace the broken plastic one. However we are having a hard time finding the metal seal ring for this new piston; is this important? Do we need to...

    Transgo kit 1&2 vs SK 400

    Trans is 75 percent rebuilt with the valve body still out. My thought after reading the instruction booklet was to use the Transgo 1&2 kit and go to page 4 for spring changes in the accumulator and then use option “2” for the drilling of the valve body plate on page 5...

    Transgo kit 1&2 vs SK 400

    I have both kits in possession. My tech thought the 1&2 kit might be too racey but I think we misread the instructions a bit much.

    Transgo kit 1&2 vs SK 400

    Howdy all! We are finally finishing up the transmission rebuild and are going back and fourth on which kit to use for the valve body. Does anyone have any experience with either kit? This will be for a 454/th400 2wd tow setup. https://transgo.com/product-details/400-12/...

    Rebuild th400 or 4l80e?

    Nick, I am thinking of running this as an external cooler for the trans in addition to the cold case radiator internal trans cooler. Have you had any experience with these? https://www.summitracing.com/parts/SUM-331018

    Rebuild th400 or 4l80e?

    Not threaded but it won’t slide up and down on the shaft. Almost like the center hole of the piston is too small?

    Rebuild th400 or 4l80e?

    Nick, I am replacing the plastic accumulator piston on the valve body with an aluminum one due to the plastic being cracked. A bit of a problem, This new aluminum one won’t necessarily fit over the shaft as it’s too tight. Have you encounter this before? It will screw down onto the shaft but...

    Rebuild th400 or 4l80e?

    The turbo 400 is in a 1985 c20 suburban. The sprags look good but I figured while we are there it’s good to replace them with new.

    Thank you! This will be for towing and daily driving so rarely will I flex it above 5500 rpm Will this one not fit the factory drum? https://transpartswarehouse.com/34652a-4l80e-th400-gm-chevy-transmission-intermediate-sprag-34-element-heavy-duty.html

    Rebuild th400 or 4l80e?

    Nick, Do you recommend a heavy duty tow rebuild kit and a shift kit? This one looks good: https://www.onlinetransmissionparts.com/400-1-2-p/400-1-2.htm https://www.onlinetransmissionparts.com/MRK3400A-HP-p/mrk3400a-hp.htm

    Rebuild th400 or 4l80e?

    My tech told me it would be cooler if it didn’t hit the warmer radiator. More cooling time does make since.

    Rebuild th400 or 4l80e?

    Howdy all! I have an 85 454/th400 suburban and my first travel trailer pull (6miles in) caused me to puke out new tranny fluid out the vent tubes. The fluid came out burnt and black so I’m guessing the clutches are shot. Should I rebuild this thing (much cheaper?) or swap to a 4l80e (new shaft...
