'70 Pontiac LeMans, The Woes Continue! 461 Pontiac runs GREAT... then doesn't! Trans problems?

  • Ever heard the phrase one step forward, and two steps back? Well that seem to apply particularly well to our Pontiac LeMans project here and what is beginning to feel like a bit of a curse. Not familiar with this Poncho yet? Well it's been sitting since late summer so you may or may not have ever seen it, a little quick back story.
    What you see here is a 1970 Pontiac LeMans with a "beautiful" patina but otherwise a very solid car. Floors are good, frame is good, body panels have just a little bit of surface rust. When we picked the car up a number of years ago one of the main things that drew us to THIS particular machine is what was under the hood. Gone is whatever powerplant that originally was in this car replaced with a 1972 Pontiac 455 block topped with 1976 Pontiac 6X heads, arguably one of the best combinations you can put together for budget Tin Indian power. Unfortunately shortly after purchasing the car some issues cropped up that made us question a few things so the engine and transmission were removed to be rebuilt.
    The engine went to a company we were doing engine building with at the time Performance Research Inc and the TH350 or "Turbo 350" transmission was sent to Metro Transmissions for refreshing and upgrades to handle the planned power. After the engine build was complete and runs made on their engine dyno the engine and transmission were reinstalled in the car and it was ready to enjoy mid summer 2021.
    Unfortunately as you'll quickly see after a few hundred miles, one awesome burnout at Indian Uprising 2021, and a couple lunch drives, something went terrible terribly wrong.
    So what happened? Is the extremely expensive engine alright? Did the freshly rebuilt transmission fail? Is there something wrong with our big bad Boss Hog Outlaw torque converter from ACC? Did we put something together wrong? Just what took this thing off the road, and how expensive is it going to be to fix?! Come along and let's start answering some questions!

    Don't overthink the problem guys. It definitely has a broken torque converter. When he removed it with a prybar it probably freed up. He also said when he unbolted the torque converter from the flywheel there was no pump clearance. The internals of the torque converter seemed jammed onto the shafts.

    After watching the full video, I'm thinking the torque converter getting stuck somehow... Anything warped? Out of balance? A valve stuck?? That glitter didn't look right...sometimes a little, but the cream color?? Scratching my head on that unless moisture got in there somewhere!?

    • @LucoreAuto
      @LucoreAuto  Před 2 lety +1

      Valve body is all good, cleaned and checked everything. Only thing stuck is the 1-2 override valve when manual shifting which was done to allow hot rodding. Nothing SEEMS warped or unbalanced but, hard to say inside that converter? The glitter is an interesting mix of aluminum and what seems to be clutch material, which is odd given these clutches appear almost perfect. We'll have an answer or at least an update on this thing by Wednesday!

      Good catch Sir! Yes it is a Chevy TH350, the previous owner or owners had already done that. Honestly part of what attracted me to the car as it wasn't "all original" so we could do whatever the heck we want with it and not feel bad.

    I know what the problem is, the 455 is rejecting the mayfair maize, I ran into the same problem with my 65 GTO. Had to paint it pearl blue to get it to work right. I am guessing at the start of the video.. Stuck valve, or a welded/not releasing clutch pack. 8 minutes in and I bet you ballooned the converter.. I did that once too. I see a problem already at 9 minutes.. chevy Th350 case. Which adapter did you guys use?
    The 455 in my 65 keeps killing transmissions. 4L70 from a diesel Suburban, killed it. Th400, killed it. Th350 blows through 3rd and its gonna kill it, but I stuffed it in just to drive it around last summer. I figure I need a TKO since its originally a manual trans car, but $3000 is holding me up. When I can finally put a 5 gear in it, I need to never go WOT ever again.
    Do a Th400 instead of a Th350. Use a BOP case too.. it eliminates lots of problems. I have a core about 15 hours north if you want one...

    • @LucoreAuto
      @LucoreAuto  Před 2 lety +1

      Well... only 1/3rd of the car has been "painted" so maybe it's an argument between the front 1/3rd and the rest of it? There has been SOME conversation about painting it but I think this particular ride the most it will get is some clearcoat to protect that patina it's earned.
      Funny you mention ballooning the converter, this particular unit is rated for 1000+ horsepower and has anti ballooning plates. So, that SHOULDN'T be an issue. The stuck valve thing, that's a possibility... currently going through the valve body now to see if there's something we don't like. ALL of the clutches still look fresh and there's not sign of overheating...
      The adapter came with the car, this thing is a crazy mutt of parts ... which is one of the reasons we bought it. Nothing matches so we can do whatever we want and not feel bad 😀

    • @SweatyFatGuy
      @SweatyFatGuy Před 2 lety +1

      @@LucoreAuto I usually buy rusted rolling shells, partly because the entry cost is a lot lower and I have plenty of time to do the work, and I can build it the way I want it. Only have two pre 1979 cars with number matching engines, the 72 GTO and the 72 455 HO Formula. Have three 79 Trans Ams with the original engines in them, but they are all 403s. Everything else either came with a 350 or an empty engine bay. The Cuda is a 318 car as far as we know, has a 340 now, but I didn't build that one. I'm just its caretaker.
      I had a Boss Hogg converter in a 700R4, it made it about 600 miles and dumped stuff in the trans. Something went away inside it. I didn't cut it apart to find out, but chunks in the pump means the TC died. I build all my transmissions, and also a few for friends, had a shop back in the 90s where I did lots of them. That is the only one I ever had where the TC killed the trans. Could be a fluke, not ripping on them. Also my 455 ballooned it with a 3.42 gear behind it, the stall kept going up and up every time I would hit it.
      455s are rough on transmissions, particularly in heavy cars like a 70 GTO or LeMans. My 70 GTO is 4100lbs, and its a no AC car too. Hardly any interior in that thing so I have no idea where all the weight is.
      Back in the 90s everyone said a Vega TC was the way to go for a cheap stall. I put one behind a 11:1 400 in my 79 Formula with a 4.10 gear. The first stall was 3000ish, the second one nearly 4000, then 4500, then 5000, then it wouldn't even spin the tires. I put an L88 style unit in it, they call them 400 high stall TCs, was only $120 from the local trans shop back then and gave me a 1900-2200 stall behind 400s and 455s. More than 2500 with a 455 is wasting torque, so they worked quite well. Drove like a stock unit, until you opened it up.
      What yours was doing sounded like the VB had a stuck valve that allowed reverse to be applied with forward gears, kinda like a trans brake does. I had one of my Th350s weld the forward clutch pack together, thanks to the ex standing on the throttle when it was slipping from low fluid. Put it in reverse and it would kill the engine, it would also move forward in neutral.
