    I want to replace my current trans with a TH700 and am wondering if I should look for a 208 or a 241 case with it.The 88's and up have stronger trans,Right?What's the diff. in the 208 and the 241's(besides the 241 having a slightly lower lo range).Any problems with swapping to the 700/208(241) that I should know about.Currently have the Th350/203 combo in it.I'll be running 35" tires.Thanks.

    I'd go for the 241, there seem to be more aftermarket parts available for it. Plus I wasn't very happy with the 208 that i used to have in my '85, especially the shift fork pads.

    Try to find a 241. Better low range, better oiling system, possible a little stronger. I like mine a lot. It does sometimes need some force to shift, but thats my only complaint.

    Is the 241 a "shift on the fly"?I mean can I shift it manually without a vacuum source or otherwise?I know the Q sounds stupid.I want a T case that I just can bolt up with no headaches.I'll be looking for one already attached to the trans to save some problems.Should I grab the driveshafts too?Or will existing shafts work?

    The 241 is supposedly shift on the fly, but every now and then, when I do it sometimes it grinds. Then I stop, put it in N, and shift. But your supposed to be able to shift into 4Hi going 55

    the 241 is a good case, go with it. and there's more after market stuff for it. it's strong enough for my suburban with 36"s. i've never shifted while moving does it actually work?

    people that get good mileage aren't having any fun!

    It's supposed to. So is the NP 208. As long as your hubs are locked in.

    I don't do it. I don't want to know if it's possible.

    I was more concerned about not having any weird ass vacuum lines...is that only for the later model frt. hubs?The T case is just a manual shifted unit,right?

    241 is a manual case, no vacuum lines. Only consideration is that '90 and later ones will probably have an electronic speedo output. 241 is a much better case than a 208.

    I'd grab the driveshafts regardless. The front shaft should be pretty much the same for all the solid front axle trucks. The rear shaft from a pickup may be too long, but getting it shortened is much cheaper that buying a whole new shaft.

    I like my 241/700r4. It is holding up well. I shift mine on the fly all the time. I live in snow country and shift in and out of 4 wheel drive under 55 mph with no problems or grinding as road conditions vary a lot around here. I just let off the gas and shift.

    The 241 will bolt up just like any other case really. My 241 is dog simple. Think of it as a slightly improved 208. The 89 would prb. be the easier swap than the later models. Also, make sure and check the tag on the back, knoowing the General, they might have stuck some 208's in just to get em off the shelf.

    I read that in the old brochure for Blazers that the 208 was shift on the fly under what I believe to be 15mph.

    I personally put it in N then 4 just to be safe...

    thats my ¢2
