easiest/ cheapest transmsiions swap

so i have a 1980 cj7 4.2L |6 and the dreaded SR4 went out in it. i am trying to get a used transmission from a self service junkyard but i need to know what transmissions have similar bolt patterns to the SR4. also i wan to know if it would be easier to keep my bell housing and get a new transmission or if i should get the bell housing with the tranny i buy. right now i just wanna drop the tranny and put the new one on w/o an adaptor kit b/c money is very tight. any advice will help

Only swaps I know of involving the transmission only and no other parts swapping would be another SR4, a T4, and the T5. I have all three and prefer the T 5 only when used with the correct tire size and axle gearing.

If money is tight then any swap to a different tranny is not a good idea. Drive shaft adjustments, adapters to motor and to the transfer case, clutch, shifter boot, all add up and can easily approach the 2 grand mark. Your transmission last over twenty years so i did ok. On a budget, replace it with another sr4.

Not sure if high speeds matter but the sm465 will mainly act as a 3 speed and give you the same final gear. Also these can be expensive in themselves. But it and it's sister tranny are very strong. Keep in mind the transfer case too. That can get expensive with an adapter. It's a short tranny and the modification needed to your existing shafts might not be that bad on price.

Was it wrecked? I'm always leary of vehicles in the salvage yards with no signs of being wrecked. It's great for sheet metal parts and stuff that doesn't really wear out. But for the drivetrain, It tells me either it was in a flood and there might be water in the engine / transmission / t case, OR one of those items is bad and cost too much to replace it than what the vehicle was worth so the owner scraped it. So it's kind of a gamble.

The t4 is a slightly better version of the SR4 with the standard shift pattern with reverse in the more common location. To me, they feel a bit tighter too.

I have a complete T150 transmission and Dana 20 T-case, with bell housing, clutch and pressure plate. I pulled it out of a 1975 CJ. Will fit perfectly. PM me if you want it.

well i got down and dirty and now i think its actually a T18 because the shifter is directly ontop of the gear box and uses a fork design to shift it. but the input shaft is not the right size so i'm back where i started

The t18 came in all manner of input shaft sizes, what is the challenge with the one you have?
