Re: Budget Build 1985 K20
4l80e swap complete! However, it fought me but I won.
The first problem I had was when I tried to tune it using the setup wizard in the Edelbrock app it wouldn’t get past the gear indicator test meaning I was t recognizing me shifting through the gears. I knew it something to do with the pressure switches after a few tests with my ohm meter. So fluid drained back out, front drive shaft back off, crossmember removed, drop pan and I found the my trans builder forgot to plug in the switches. Ugh! What else did he forget? So back together it went. Next problem - on the first road test I couldn’t get it to lock up the torque converter. After many calls with clueless edelbrock tech support. I was ready to scrap the edelbrock trans controller and go with a different unit. Ironically the only review on Summit mentioned this problem and a 1 star review. So I started researching trans controllers that were canbus enabled as come across compushift. The more I researched i was convinced they must be building them for edelbrock. So I called their tech support and the first question he asked me if it was a 4x4 and was the transfer case wire ran. And I told him it was. He told me to disconnect it because I do not need it and the 208transfer case won’t send the correct signal for it. Problem solved! The funny thing is is that I called edelbrock before I bought this and asked them what type of signal was the transfer case supposed to send and they couldn’t give me an answer. Long story short if you need tech support don’t call edelbrock. The 4l80e makes this thing a dream to drive. It shifts nice and smooth cruising but when you stomp on it it will just about break the tires loose when it shifts. And 2300 rpm when going down the highway going 70 ain’t bad either! Not many pictures from the install but this is what I got.

Re: Budget Build 1985 K20
Impressive work as always. Since it seems your budget build is in its final stages, when does the no expense spared build start? LOL
Love the truck, and great build. Very impressive. Sidenote, I'm guessing you're still riding single track so if you're interested in riding with a buddy of mine and I once the weather breaks PM me. He's on the west side up by the dunes and rides all the time (retired) and I still work so rarely ride but got the XR400 out and got it running this winter so ready to go once mud season is over. |

Yea, still riding single track. I been doing a couple small projects on my bike this winter as well. I added a headlight and taillight just in case I am on an atv trail to try and prevent me from eating a grill on a side by side. I also put on a gummy rear tire, mousse bibs and a Rekluse clutch. When the weather breaks I will shoot you a message and maybe we can meet up. As for that no expense spared build. It will be my 51 3100 five window. It will get a ls3, 4l80e and bagged with all natural patina. Hopefully starting fall of 2024!

Re: Budget Build 1985 K20
Talk about a project that is never done! I couldn’t keep the 4l80e in what I would consider a safe temperature. It would get to 220 degrees in short trips when the ambient air was 60 degrees and I was afraid what it might get to in the middle of summer running the ac in traffic. I just had it hooked up to the trans cooler in the champion radiator. So I ended up getting the biggest Derale stacked plate cooler I thought I could fit and just using it instead of going through the radiator. Had to build some brackets to get it bolted to the core support. I took it for a drive this afternoon and temps were about 150 degrees. Success!
