hey guys ive had a stock 5spd '93 sc300 that was once my baby now sitting totaled in my garage for the last few months. i was looking for new cars but then came across an automatic '92 sc300 thats got a decently clean body for $700. I was wondering if i could get any advice on how difficult the swap would be if i was directly transferring both the engine and transmission from my old one into the new automatic one.

I have everything i need sitting in my garage it seems, just wanna make sure before i take the plunge haha. the only thread info i could find on tranny swaps was for the R154
