    Marks adapter speed sensor plug leaking

    I am in the end stages of my ls swap and I have transmission fluid leaking from the brass freeze plug that blocks off the extra hole in my marks adapter just after the gm trans speed sensor port. Has anyone else had this issue? If so how did you fix it? Also has anyone ever tried to braze or...

    Air intake: I spent way too much time researching the issue of Air intake and all of the pundits opinions across the different websites concerning LS-1 swaps. My final conclusion was that nobody really knows what they are talking about. So as long as air goes in one end and out the other with...

    A couple more photos of the mocked up remote reservoir location, and frame clearance of the AC pump. I don't have photos of the back side of the AC pump but it has plenty of clearance from the motor mounts and frame on all sides.

    More pictures of the motor placement and clearance: The placement of my motor was near center with a little bias to the driver side. As you can see in the pictures it is close but with the low mount stock Chevy Air Conditioner pump that came with my motor, and by using a remote reservoir for...

    A couple more pics of the shifter sorry I don't have any of the console installed or the modified cup holder I mention in the post above. I will add them later when I get them sent to me.

    Transmission Shifter: I originally chose to use a stock 1992-93 Toyota console shifter that had the 4 speed positions PRND32L, as opposed to the 3 position four speed PRND2L shifter that my 1994 came with. Now although this makes for a cleaner stock look I ultimately decided to use a B&M Mega...

    Thank you I am really trying to find the cheapest easiest methods I can for this swap and then post them for others who may be considering a swap like this. As for the Chevy 4l60E NSS from what I have been able to find online the NSS is just for the starter interruption It does not send shift...

    I was looking at that sensor first but I couldn’t find anything out about it. If you have any pics or wiring diagrams on how you did it I would appreciate them. I wasn’t sure if it would send the proper signal to operate the gauge or how to wire it up so I went with the one I knew for sure would...

    You are correct I wish I could blame that on autocorrect :(

    Stock oil pressure sensor for dash gauge To get the oil pressure dash gauge to work you have to retain the stock sensor and wiring. The LS motors have a sensor port that provides a digital signal for the ECM and can be used to provide a signal to the dash gauge but it requires a converter box...

    Dash gear position lights The 4L60E transmission is a DBW that displays the gear position via digital signal. In order for me to have the gear selection lights in the dash to work I had to come up with a hack or buy a fancy converter box. I chose to go full redneck and try something different...

    Turning down the temperature sensor (the Bumpkin Method) For the water temp gauge on the dash to work with my wiring harness I needed to retain the stock Toyota sensor and wiring. The problem is that the port on the passenger side head of the 5.3L Vortec is smaller (12mm x 1.5mm) thread and the...

    DBW throttle pedal assembly: Of all the modifications so far this one was relatively easy to accomplish. The pedal assembly is from the donor vehicle that the motor and trans came from (04 Avalanche) First I disassembled the pedal by removing one screw and then drilling out the three rivets...

    Motor placement: I oblonged the holes on the transfer case mount (not the frame holes) to give me 3/4” forward placement of the engine. this allowed me to keep my firewall intact on the passenger side. I also biased the motor 1/2” to the driver side measured from center of the crank shaft. I...

    Motor mounts: I used the original FJ motor mounts and rubber, with a set of modified universal LS swap mounts from advanced adapters 713088 : GM Vortec LS series engine mount kit | Advance Adapters They aren’t the most elegant I have seen but they were simple and easy to fit with little...

    Hey y’all so I am adding my name to the list of envious fools who made the best bad decision ever documented on this forum. I started this build in late August and worked on it up until I had to put a hold on it until I get home in April. So at this time the major parts are in and I am at the...
