I have heard that a transmission swap from the 300 to the (1995) LHS is a good swap because of the different gearings. How difficult of a swap would you rate this? My brand new transmission just started jerking and shifting badly and I'm afraid it'll downwardly spiral into the limp mode problems i was having with the first one, and I haven't heard of the limp mode problems with that newer transmission.

Any input? Is it worth it? Thanks in advance
