    I appreciate the straight forward approach to this video. I've watched dozens of other ones and just can't follow them because the host is either over the top in personality or they just can't convey the information. I'm only 10 minutes in and Im engaged, not put off and have already learned stuff. Excellent job.

    I had a `67 Impala SS with the early design pan and filter. I read that it was better for racing because the oil would move to the rear of the pan under hard acceleration and the filter pickup was there.

    Great video and breakdown on each step of maintaining the Turbo400. Just what I needed to start my education on the Turbo 400. I have an original older Turbo 400 from a 67 Camaro, but it has a bigger modulator with a threaded looking screw coming out the end and a separate vacuum port. Should I continue to use that style of modulator? Thanks.

    I have an TH 400 that was working fine then from shut off tobstart the next day, when I put it in reverse it acted like it was trying to go forward, when I put it in 1st 2nd and third, same thing wanted to go forward but would engage in all slots starts in neutral and park. Fluid was couple quarts low, replaced it and no difference. Have taken from vehicle and pan off had clean no burn fluid, pan had minimal Grey matter no chunks etc. Will I have to rebuild whole trans at this point? Ps shift wire on side was disconnected, valve body was super clean also. Your input would be appreciated if you do such things! GREAT CHANNEL and Most Informative of any I have seen! Thank you and yes I tell my friends about this channel too are you a trans shop also?

  • @ourkid2000

    Great video! I have a question about the oil pan. I have a Th400 with the old type filter and my pan has started leaking so I’ve ordered a new pan, but it’s without that D shaped groove in the bottom. Will it still fit?

    Great video my 78 GMC came with a 454 turbo 400 with the deep Pan with the spacer under the filter did those come with any heavy duty internals straight cut gear's etc?

    • @SouthpawAutoworks
      @SouthpawAutoworks  Před rokem +1

      Straight-cut planetary gears are typically found in TH400's used in motorhomes, dump trucks, etc.

    Leaking, seeping, and dripping. Tail-Shaft housing just won’t seal.
    I’ve used BLACK tranny sealant on both sides of a gasket.
    I’ve used BLACK tranny sealant on one side of the gasket.
    I’ve used just the gasket without anything.
    All times, I’ve torqued the 6 bolts to 20 ft-lbs.
    I’m ready to shoot this TH-400.
    Any ideas?

    • @SouthpawAutoworks
      @SouthpawAutoworks  Před 5 měsíci +1

      That's frustrating...
      Hard for me to say without seeing it, in person. But...
      Are there any dings/dents in the mating surfaces on rear of case or front of extension housing?
      Are there any raised edges? If so, they will cut/damage the gasket, resulting in a leak. Or make it hard to compress the gasket correctly...depending on location of raised edge.
      If you don't already know, when using RTV it's super important to keep oil away from it, while it cures. Getting the mating surfaces clean, and dry, AND keeping everything clean, while the RTV cures, is a must. Otherwise the RTV is useless.
      That torque value is good.

    • @josephbrandt3359
      @josephbrandt3359 Před 5 měsíci +1

      @@SouthpawAutoworks I followed your instruction… I followed the PERMATEX instructions.
      I think I may have got it sealed now.
      Mating surfaces are LAZER STRAIGHT.
      After applying the “ONE MINUTE GASKET MAKER, I put a space heater on the areas that need to be sealed. The temperature I was able to heat up those areas to (Tail-Shaft Housing & Speedo-Housing) was 115*F…
      I left the heater in place for 36 hours and I know that was overkill, but it is due to my job and responsibilities.
      However, I will know more in a day or two. I’ll update you.

    How do you tell the difference in the 400 and the 350 transmissions

    • @SouthpawAutoworks
      @SouthpawAutoworks  Před rokem +1

      There are a number of ways to tell them apart (oil pan, servos, etc).
      If you're interested, we can put together a short video on this topic....as time permits.

      I have a 1990chevy truck I built a 350 and changed it over to a carburetor it has a 46L60E trans in it and it doesn't change gears because I don't have a computer in it anymore what can I change the transmission to for it to work like it is supposed to

    • @gregburbage4954
      @gregburbage4954 Před rokem +1

      4l60e

    • @SouthpawAutoworks
      @SouthpawAutoworks  Před rokem

      A 700-R4 is almost identical to the 4L60E. But, no PCM needed to operate the trans. Instead, it's controlled by a Throttle Valve and a Governor.
      The governor is very similar to the TH400 governor. The Throttle Valve is located in the VB (valve-body), and is controlled by the TV Cable, that is attached to the throttle linkage, at the carburetor.
      Note: Some years of 700-R4 are also known as the 4L60......not to be confused with the 4L60E.
      At a glance, the early 4L60E and the 700-R4 look identical, from the outside. However, there are some ways to quickly tell them apart. We can put together a video on that topic...as time permits.
