I bought what I thought was a TH350 through an auction. When we unloaded I noticed a square electrical plug on the side above the pan. THe plug has 4 pins in square female connector. What is this and what do I need to do to make it work like the old turbo 350? Help, no more money for another...

Make sure you have the converter that goes with the lockup tranny. The old type will fit, and even work on the lockup tranny for about 2 laps. The input spline only engages 1/8 inch!

Thanks racer17j I can use all the help I can get. That also tells me to plug the vacume module off. Do you mess with the govenor pack on the side to get different shift points?

arent you guys actually talking about a turbo 200??

they came in 81 camaros, metrics etc. and look like a 350 except for the plug. and are lock up.

66jj The metric 200 you are refering to has metric embossed in the pan usually. And it has a one piece case (in other words the tailshaft does not unbolt). The turbo 350 came in a lockup version

Powerglides i think i have the problem you are talking about above with the wrong torque converter. Is there any numbers on the converter that will tell me if i have the right one or not?! We bolted everything up fired up the engine put her in gear nothin happened. pulled the tranny cooler line no oil pumping anywhere. So i think the stupid transmission guy gave me the wrong converter. All the help is appreciated. dfowlr88d

If you cross sectioned the converter the lockup style will have a flat surface where it bolts to the flexplate,the older style non-lockup's are round, sorry if it's confusing it's hard to explain.Also the spline will be deeper to accept the longer input shaft but that may be hard to judge by looking into the converter.

David, The pump coupling is the same in both trannys. So if you are not pumping oil it is low on fluid (new tranny and converter put in 7 quarts, start car and add 2 more, then check level. Or you have a pump problem. Did you install the tranny/converter as a unit or did you bolt the converter on then install the tranny?

i put it on as a unit. Will it not pump oil at all if there is less than 7 quarts of oil in it?

I think I had to add 12-13 quarts to run a T-350 with small cooler.
