    I have been looking for a solution to this issue for years, thought I'd see if any of you folks knows. What causes a TH350 to dump fluid (up to two quarts) onto the floor after sitting for more than a week or two? I recently swapped a TH350 from one Camaro to another, replaced the front and...

    Hey hotrodders, I'm in the middle of my TH350 rebuild. I've started putting it all back together now. After installing the low clutch pack, I put the clutch spring in the case and install the center support. Everything seems to go together well, but no matter what I do I can't get the center...

    Hi all, so I have a 72 buick skylark with a buick 350, and a th350 trans. I want to drop a chevy 350 into it, and I'm looking to get an accurate idea as to what this swap will look like. I have read some posts that say it is an easy swap, that the chevy350 fits right in and bolts up to the th350...

    I have recently had to replace the TH350 in my 1981 Silverado because the transmission wasn't engaging. The transmission in it now has new fluid and filter and indicates that the fluid is full. This transmission isn't engaging either. If I feather the accelerator it will begin to creep in...

    Hi, i did some searching but couldn't find the info i'm looking for. I'm rebuilding my th350, putting a shift kit in it and a new converter (high stall speel), but i'm not quite sure what oil to use, some say type F will destroy any gm tranny, some say Mercon with any number will work fine, some...

I've already decided on promaxx performance heads (http://www.summitracing.com/parts/pmx-2168), with steel roller tip rockers. I have an edelbrock torker ii, and will be...

    I have just replaced a th350 in my first car. It is a 1978 Chevy Cheyenne with a L6 250........ So the transmission has less than 200 miles on it and it wont shift to third when the truck is warm. It does it fine when the truck is cold. Also it makes a whistling noise when it shifts to 2nd and...

    Ok. I bought an 1980 el camino with a 350 and 350 tranny not running. When i got it it had a flat tire, pumped the tire up and the car started rolling!!! First thing i did was check the linkage on the tranny and of course it was disconnected, bolt was missing so i bought a new bolt and put it...

    Title says it all. I havent really dug into it yet, just did some researching across other forums to see if it will work, but i couldn't find anything too in depth on the subject. First off, I have the orginal speedometer and speedometer cable in the car (attached to the speedo not the tranny)...

    Does anyone know a parts supplier that carries TH350 manual valve "S" links ? My local wrecking yards won't sell parts, only complete trannies. Have checked many suppliers. Thanks Jerry
