So I just got my oldsmobile 307 v8 rebuilt, I got a feeling my th200 tranny is going to give soon. Was curious if a th350 will work with the old's 307 v8?
yes, or if it's a Chevy TH350 add http://www.speedwaymotors.com/Chevy...1&cadevice=c&gclid=CKrOo4OStc0CFQ6maQodL9wDIg
That's the way to go ..got $150.00 for my th200 , from a drag racer who is going to spend 2 grand on it , go figure
I know it seems strange, but the Super Stock and Stock Class drag racers have been using the TH200 for a few years now, and it's even making it's way into Competition Eliminator. There are a few performance components being made, and several vendors supplying complete racing transmissions. They are lighter, and geared better. Look up Scott McClay Engineering, Thomas Arnett Transmissions, or Leon Miranian's Turbo Flite Racing Transmissions. I am Butch/56sedandelivery.
I would't use one either; too costly and requires far too much maintenance to keep them reliable. It was only posted due to the post before mine, to show some folks are using them successfully. TH350 has issues also; the biggest things are the "lag" between the 2 to 3 shift, and the weak intermediate sprag assembly. Ever since my first TH400, I won't use anything else; although I do have the stuff to beef up a TH350, including the 36 element intermediate sprag assembly AND one of the mechanical diode assemblies I bought because I was't totally sold on the 36 element unit; then again, the mechanical diode is actually a Ford piece, modified to be used in a TH350. It has been problematic for Ford, so I can't really see it as solving anything for the TH350. Of ther two, I'd probably use the 36 element piece. Some guys swear by the TH350, some swear at them, I'm a little in the middle somewhere because I've gone through a few in my DD truck, that now has a TH400. To the OP, stick a TH400 in the car, and don't look back. JMO. I am Butch/56sedabndelivery.
He only has a 307. A TH400 causes temptation. I stuck one in my brother's '90 truck rather than spend the money on rebuilt TH700. Then since we had a good trans, we put a BBC in front of it.
The 350 trans is a good one for a mild car, if you don't want or can't afford overdrive. Although they're getting a bit scarce these days.... and I would not install one unless I overhauled it first, or at least got to drive the car it came out of. They usually have something worn out inside. And they are prone to leak.
I believe the OP and the other guys are talking about the weak and th200, the non overdrive little brother to the th350 that was used in A and G bodies in the late 70's- early 80's. Not one of the best but it should be plenty to live behind a 307...
they died early when the cars were fairly new, I doubt they somehow got better all by themselves. But it was a good trans behind a 4 or 6 cyl engine, which is what it was designed for.
hey OP, just out of curiosity, what is your olds 307 in? the 2004-r mentioned above would be a great trans if you have the rear gear to pull it off, or a rear end that you can easily swap gears in. Edit: I just looked at his info and he only has two posts and lists a 1990 buick lesabre estate wagon as his car, so im gonnna go out on a limb and assume A: he aint coming back to check this, and B: he had a 2004-r to start with and not the th200 I wrongfully assumed from his use of that name. So we are talking to ourselves haha
I am curious now, you drag racin guys mentioned people using the th200? Why are they modifying those when there are tons of parts and aftermarket cases and such for th400's and powerglides? like I would think starting with a th400 and copying the rossler 210 that the unlimited drag week guys use would be better anyways
racing guys are after the quickest ET, and figured out that if you take a small lightweight transmission, and beef it up so it will hold up to the torque, you can go a little bit quicker than you would with a heavier transmission. They don't mind getting only a few miles out of a transmission before overhauling it again. Not quite what you want in a street car.
After 2 grand or so spent at the Trans shop the 200r4 really is a great transmission. The price of admission is high. Could always learn and do it yourself.
Opps hit it too early.I bought my mom a 70 Nova 250 - 6 went over 200k miles on the TH 200 but I wouldn't use it for much else. Once again sorry...
