I can’t take pictures with the phone I’ve got otherwise I would lol. It’s down to bare frame at the moment and I have a new cab floating over it. The bed is on stands outside of my shop. The reason I’m doing this build is because I had a couple important people in my family pass away and I decided to dedicate a truck to them. I was thinking about putting a newer motor and transmission in it but with winter coming I’ve got a lot of other things to do for the moment.Welcome to TTS! Fill in your signature with all the details of your truck, this way all will know what your working on. Oh, and we all love pics lol there's lots of members here to help with you build
The 4L80E should bolt up just fine, but the electric connections will be different than what was used in 95. there also may be different internal and external sensors / solenoids between the two. ODB1 and OBD2 are different animals. is there a reason for the swap vs a good rebuild and upgrade the existing? I'm sure others here more knowledgeable will chime in that know what all needs to be done for the swap.
The 700r4 is a 4l60, definately NOT a 4l80e. You're getting hung up on obd1 vs obd2, alot of that stuff can be interchanged. 4l60e and 4l80e use the same trans crossmember. There are slider motor mount plates to help offset driveline length. There are options, but until the OP figures out which direction he wants to go, there isn't much any of us can do for him.TheFermanator is right, there's lots of combo options out there but it all boils down to your budget and what you want to do with your truck. swapping the tranny also means having to shorten / lengthen drive shafts plus getting them balanced too. fabbing up rear tans mounts and more sometimes. The electrical system can cause you nightmares depending on what you go with, a newer trans is setup for obd2. if you are scrounging in a junk yard you might get lucky and score a complete wire harness and ecm but it will still have to be tuned for the bigger trans otherwise the shift points may be off or not shift at all. some of the newer trucks also use speed sensors in the rear diff and front wheels too.
another thought depending on your area's emission laws, you can conciser going to a carbed fuel system and beefed up old school trans that uses no electronics. Kinda like a rat rod! I think the 700r4 is the same as the 4l80e just without the electronics.
