Well I'm glad it works haha I can't imagine how until I see it but it's gonna be amazing to have an accurate speedo. I just assumed my stock 1950 cable will hook right up to a th350. Hope I am correct. My wife loves the car. We clocked many miles before we had a baby. She doesn't like the car scene culture though. She's getting to know other wives in the hotrod club I am in and that is helping
The original speedo cable will connect to the TH350, but it may or may not be long enough... look at the teeth on these gears...they are different tooth counts, the same diameter, and look really strange, but they will all work with the same drive gear.
Man that's incredible. Never thought gears could do that. Always assumed teeth had to remain equidistant and therefore the number of them directly affected diameter. Well if it's not long enough that's good news to know a modern is the same as my old one. I can just get a 73 nova which is what the donor motor and th350 is from. Or similar. Just ask my connection at napa or nuway to find me the right length Gm one
They are color coded I guess so I'll have to see what I have already then I can swap one and get where I need to be. I wonder that the most common rear end was in a automatic 1973 nova 350/350? cause if it was close to what I am doing then I am already good to go
3.08 with 14" tires, which is probably pretty darn close. The important thing is to make sure the driving gear, on the output shaft, is one that will let you get where you need to be by only changing the driven gear. btw you can do amazing things with the concept of a "gear"
Yea gears are awesome. I'm sure one can gear an iron duke to function in a semi. Not too far from Chevy relying on the stove bolt in thier full size (2 ton?) trucks until 55. What's that a photo of? Also my end goal is 3.08 so maybe I'll just leave it. I heard any 55 to like mid 60's punpkin will swap into a 55-57 rear and and that's what's going into my car. The one I (think) I have lined up is a 3.36. I would love 3.08
3.08 is harder to find these days. The pumpkins do all swap, although there are some 62-63 Chevy II pumpkins that fit but are light duty, and use different axle splines (I think). That photo is a random wood gear picture from the internets.
Gotcha. Yea my buddy runs 308 with a stout 350/350 in his 52 olds rocket and I enjoyed how it drove. Anyone in the Rochester area reading this that has 3.08s they'd sell can private message me! I am getting two 57 rear ends; one is smoked but in nice shape, the other is a spare that's all nasty and has bad brakes. I'm going to combine the two and hope for the best. I think they are 3.36. Maybe 3.73 which I would hate. 3.55 is what I have now and I dreamed of overdrive or 308
My wife is generally pretty cool with it, but we were at a New Years party when I posted that last night, if she had noticed me sitting in the corner in the middle of a party, on a I-pad I borrowed from one of her friends, posting on the HAMB, she would have snapped! that was probably well across the "sick obsessive, self centered bastard" line.
I was planning to fill up this transmission soon… I used Dextron iii correct? I cannot verify that's that's what's in there.,.. I drained the body of it hit the torque converter has some in there still All brand probly fine? Was gonna just grab what's on sale
I know you're in the middle of a TH350 install, but a 200R4 overdrive and a 3.55 is a nice combo. The 200R4 is essentially the same external dimensions ( 1/4" here and there) but should use the same trans mount and driveshaft. Not meaning to throw you a curve ball, TH350 and 3.08 or 3.36 gear are nice combos for a cruiser, I've run both.
The lowest number Dexron you can find is probably what you want for fluid. Don't worry about what's in it now....
Thanks guys. And I would love to do an overdrive transmission at some point, but right now, it's not in the budget, and I need something bulletproof. To me, that's a TH3 50. I just need to get this thing going down the road by spring…
I ended up with 8 quarts of this, for $22. Some tricky wording… "For use in vehicles previously serviced by Dextron III or mercon" I'm sure it's fine?
yeah. Might need another quart or two to fill it completely, but you can start with 8 and see what happens. Make sure you only put 4 in before you start the engine, or it will overflow...
Ok cool thanks. Got s multi pack of O rings for the dipstic. Hoping it's as simple as finding one that fits in the groove
Don't fill it BEFORE you put it in the car; do that AFTER everything is more or less ready to fire, and all lines, hoses, and tubes are installed/connected. At the very least, you'd need to have a slip yoke or plug in the tail shaft to keep it from leaking transmission fluid all over the place when the engine/trans goes in. Nothing worse than watching your hard earned $$$ spreading out across the garage floor, and having to clean it up, only to throw it all away. We've all done that, or know someone who's done just that (roll eyes). A quart in the converter, and the tranny fluid used during assembly is fine; just don't start it "dry". I am Butch/56sedandelivery.
the O ring has to fit in the groove with just a little bit sticking out...should be 3/4" od, 9/16" id, 3/32" nominal thickness, I think. Like a -113 size
Thanks butch!i had NO idea the skip yolk keeps fluid in. The skip yolk I have came with a Saginaw 7 bolt 3spd. It fits the th350 perfectly, or so it seems.... Squirrel thanks. I got a multi pack for like $7. If it has that one it there I will try it... If not, it's on my NAPA list
Ahah. As you can see I am learning at a RAPID rate. My backstory is simple: I grew up with Japanese cars that had specific parts for each and computers that made sure you didn't vart from that. The Chevy (1950 deluxe) is my first classic car. This has been awesome. I appreciate the constant / quick / kind help
Good call. The slip yolk seals it too? I guess I have no reason to fill it before I put it in... Just made / making sure to do all The maintenance on it (kickdown, filter, gasket, oring)
The oring worked great. Forget what size, but it's nice and snug. I assume there is never any fluid pressure against the tube anyway, maybe a splash here and there... I'm getting ready to join the engine and Trans I just used most of my bolts for the job to mount my load leveler to the outside corners of the intake manifold so I have to buy some, then I'll be slapping everything together
When the car sits for a while, some times the torque converter drains back into the pan, and the fluid level goes up pretty high...that's when you'll find the leaks at all those places like the dipstick tube, kickdown cable, shift linkage, speedo gear, etc.
The best way I've found to drain a converter is to take a small hose with the converter laying flat and stick it as far down as you can get it. Wrap a shop rag around a blow gun to seal the opening in the converter and pressurise the converter until oil quits flowing from the small hose.
