Finally gonna break down and do the 60-80e swap. I have an 80 out of an 05 van and having it gone through n freshened up. Ibonly have a couple questions.
1. Will it be easier to use the "tuned by frost 60-80 conversion harness" or just do the repin and segment swap???
2. The crossmember... Is there one that i can get from a salvage yard and bolt right in or should i just cut and modify the one i have?
3. Which front yoke will i need? A part # or link would be sweet.
Between working 7 days a week and only having my phone to do some research here and there when possible im kinda at a disadvantage not taking the time to research it myself so all help would be greatly appreciated. O and truck is 04 rcsb thanks

 

1. It's easier to use the Tuned By Frost simply because it's quite literally plug and play, no thinking required. Does require some codes to be disabled and the ratios updated in the tune, but no segment swap and no real thinking involved there either.

2. The crossmember will have to be cut and welded. The difference on the 3/4 ton trucks is that the mounts for the crossmember are located differently on the chassis than the 1/2 ton.

3. No idea

 

Are you 2wd or 4wd?

 

Assuming that you are 2wd, you are in luck because I did this swap 2 days ago.
1. do not buy an aftermarket harness! all you have to go is swap 2 wires in the Canon plug and leave one out. then get a connector from the parts store for the input shaft stored sensor and run 2 writes to the pcm ( you need to add 2 pins to the red plug. # 22 & 23 I think). that's all of the wiring you have to do. I'd that's worth $150 to you then have at it.
2. for the crossmember you just need to make 2 cuts and cut the middle out (wider than the trans). you'll need 2 pieces of steel that are 1/4in thick 4in wide and 10in long. once you have the 80 bolted up then starch the middle part of the k member to the trans mount and get everything level. track in the steel to connect then, remove and weld completely. it essentially moves the mount back about 6 1/4 inches.
3. you'll use the stock 80e slip yoke and the stock driveshaft. connect the two with a precision 447 u joint.
4. you'll also have to lengthen the rear oil cooler line by cutting it and adding I'm about 6in of rubber trans house. the front just had to be straightened out a bit too reach. I used the stock van dipstick tube.
get a tune for the 80 and you are good to go!

 

One other question. The trans i have is a newer style 80 will that be a 32 spline? and what yoke length will i need to get?

 

you will need a turbo 400 short yoke, then you can use your stock driveshaft, no need to cut it. i bought the tuned by frost harness, easy, simple, and runs off the 60e tune, so you dont have the low speed lock up.

 

Ok cool thanks
