    04 LM7 into 87 K5

    What i meant was, with a switch wired up, will the pcm shift the transmission correctly? My speedometer is going to be cable driven off the transfer case in its stock location

    04 LM7 into 87 K5

    Thanks vbb. Could anyone touch on the high/low range switch? I know ppl are using a switch that they either epoxy or screw to the shift gate so it is actuated when put in low. What pins on the pcm do I wire this switch to?

    04 LM7 into 87 K5

    Right but i *believe* if i use the adapter, i can get my vss signal at the adapter (between transmission and transfer case) - this leaves the speedo cable in the transfer case untouched. So i *think* that is the best of both worlds unless it changes driveshaft length or the pcm needs to see vss...

    04 LM7 into 87 K5

    Vbb I definitely appreciate all the advice. I am mainly trying to avoid any tuning type complications as the tuning portion of the build is outside of my scope of abilities. Since i would need an adapter anyway i think the one that is machined for the vss is a good way to go. Mainly asking if...

    04 LM7 into 87 K5

    Thanks CalSgt. The Dakota Digital signal not being good enough is what I found too. So then the Walters piece would take care of the VSS needs, and my tuner should be able to make everything work? It does look like I would lose my cable driven speedo though?? Then all I would need is an output...

    04 LM7 into 87 K5

    All i found when researching was problems getting the 4l60e to work correctly. Maybe just bad tuning?

    Yes it does, good call. So i am wondering now if i should keep the 4L60E or the 700r4

    04 LM7 into 87 K5

    So if using the 4L60E and NP208, the PCM needs VSS from the transmission, transfer case or both? Would I keep the factory VSS on the transmission plugged in and also add the Dakota Digital pulse generator at the transfer case cable input?

    04 LM7 into 87 K5

    Can anyone explain what they did to make their 4L60E work correctly with an NP208 ?? I have searched for weeks and can’t find anything. I know there are Several VSS options but when i dig a little deeper nothing seems to work correctly or put out the right signal. Which leads to poor...

    Remove 4L60E

    Pulling the 04 2wd 4L60E out of my donor truck for my K5 LS project. Will I lose fluid from the tailshaft if I drain the pan and cooling lines first? I dont have a plug or spare yoke… Can I allow the LS to tilt back or will it hit the firewall? Doing this outdoors so hoping for smooth...

    Starter wiring for LS

    Thanks guys. I guess what I was getting at was the 87 bulkhead wiring. I want to use the factory key switch. I believe I can use bulkhead exciter for the starter, hot and crank wires to power PCM… I dont need a start signal to come from the PCM correct??

    Starter wiring for LS

    Wondering if I can just use existing starter wiring to run my LS or is there a reason it needs to come from the PCM? This is on my 87 K5 with a TBI 350

    700r4 Manual Valve Body

    Crazy pic!! Engine braking it is!

    04 LM7 into 87 K5

    This is the down and dirty info I have been looking for so thank you for that. I was worried the 4L60 would nickle and dime me to get everything working correctly. I dont have a huge build budget. I think I have the 700 figured out and can keep the speedometer which is a plus. Its also a fresh...

    04 LM7 into 87 K5

    So then in theory if I ran the 4L60E I shouldn’t have to change D/S length, and I think the mounts I found will work with the factory crossmember. If I run the 4L60E, doesn’t the PCM need to know if I am in high or low range? (Additional sensors/wiring for the 208?) I do know it will need a...

    04 LM7 into 87 K5

    Also wondering the above question but with a 4L60E. I think the 4L60E is the preferred transmission over the 700r4 but will it move things around or fit in the stock location? This would be with the original 208 Tcase and an adapter.

    700r4 Manual Valve Body

    Hey all, I am getting ready to pull the trigger on a manual valve body, I have the option of engine braking or no engine braking. This truck is going to see a lot of street use. Which would be more preferable and why? Is the engine braking abrupt or is it comparable to say, letting off the...

    For those of you that kept the 700r4, did the stock LM7 oil pan clear the crossmember?

    Sorry, I think I meant hot with key on AND crank. Need a source for PCM. Was thinking one of the fuses under the dash

    Thank you, yes I will have it tuned as a manual. I think I have someone lined up to do the tune

    04 LM7 into 87 K5

    Thank you for the reply and taking the time to spell everything out. Do you know if the oil pressure sender is required for the pcm? I wanted to take it out and replace with my k5 sender to keep the factory gauge. Also I need a key hot in crank source on the K5. What location are people...

    04 LM7 into 87 K5

    Hey all, I want to pull the LM7 5.3 (dbw) of my 04 2wd and drop into my 87 K5. My plan is to use the existing 700r4 and existing transfer case (both fresh rebuilds) in the K5 and use a manual valve body and ratchet shifter. I think this will be a fun set up. For torque converter lockup I was...
