Stop messing around with TH350's and TH400's. Put a glide in it and it'll be the last tranny you'll ever need.

The JW transmissions might be OK, don't know cause I've never known anyone to use one, but they can't adjust a converter right to save their lives. We've sent one back for a customer several times now and they still can't get the damn thing right.

Just my opinion on both subjects.
