Is it possible to mount a np241 to a th350

[sickquad]

Is this possible? Is there an adapter plate available that anyone knows of? Advanced adapters doesn't have one. Are there any other companies that make adapter plates?

Thanks

you will need a adapter output shaft. The stick out length on the 350 is only like a 1/4 of an inch. The bolt patterns on the rear of a 700 and 350 are the same so as long as you have a 241 off a 700 take the stock adapter for the 700 to 241 and get a longer output shaft from advance adapter and you should be ready to go. This does require the tear down of the tranny to install the shaft but Advanced adapters does make one for this aplication

it says it is for the 208 but the 208 and 241 will bolt to the same tranny

So I guess it's not that easy. I'm definitely not swapping shafts in my brand new tranny.

I thought that the 208 and 241 were interchangable, but no one makes the plate for the 241. Has anyone compared the 208 and 241 before?

If they are interchangeable, I wonder if a plate for the 208 would work if it had the right bolt pattern.

Any help is appreciated.

no mater what you need a new output shaft for the 208 or 241. It really is not that hard to put the new output shaft in all you need is the new shaft and Four gaskets. The only tools that you will need are scokets and a pair of snap ring plyers.

Sounds like so much fun. I'll have to look into this. I guess it's always better to do it the right way, even though it's not the easiest thing to do.

Anybody have any information on how the shaft would be replaced? I've never ventured into a tranny much, just shift kits and torque converters.

if you can do a shift kit you should have no problem replacing a output shaft. you should buy the Haynes GM tranny techbook. It provides a lot of pictures and good instructions. Even takeing your time it should only take at most two hours

The T350 to NP208 was a stock offering in the early 80s.

If you want to put a 241 behind the T350, just find the right output shaft and the T350 to NP208 adaptor.

The 208 and 241 are interchangable, as long as you watch the input spline.
T350/700R4 = 27sp
T400 = 32sp
