Want factory adapter from 4L80E to NP205 - 1991 is the most likely year (maybe the only year)
I'm still trying to find out info about this combo.
I believe the adaptor is the same as the 400/205 from '85 to '91.
Might ask Stephen or someone who actually has a V3500 to crawl down and get the part number off the adaptor. I have the number for an '86 adaptor, so we could compare and see if the 4L80E uses the same or different.
Good idea - I think I'll post a ? in ORD and/or main forum.
Part number wanted - <font color="blue"> 15629600 </font color> that's 15629600
I'm gonna try to find one for myself, too! /forums/images/icons/laugh.gif /forums/images/icons/wink.gif
Does it match the th400/205 adapter? IF so, I've got one I will sell. Let me know.
I think it matches the bolt pattern but not the depth.
I was going back and forth with azblazer and he found different part number for the '91 V30 with the 4L80E/205 combo.
So far, the part numbers I have on hand right now are:
'77-'84, K30, 400/205 #14022218.
'85-'90, KV30, 400/205 #15597799.
'91, V30, 4L80E/205 #15629600.
Evidently the 4L80E/205 adaptor must be a different depth because if they weren't, they would be able to use the 400/205 adaptor.
Still lookin for now - P# 15629600.
Mark, just letting you know that I have not been successful in finding this adaptor for you. /forums/images/icons/frown.gif
I have called, checked with, e-mailed and went to different shops and other places all over in search of this "rare" adaptor. /forums/images/icons/tongue.gif
I have only found one but its bolted to the assembly under the truck and is a daily driver. /forums/images/icons/frown.gif
Wanna come over and we can go "borrow" it some time? /forums/images/icons/shocked.gif /forums/images/icons/tongue.gif /forums/images/icons/wink.gif /forums/images/icons/grin.gif
Is that ethical? /forums/images/icons/shocked.gif I am also looking on info to modify the 241 adapter that I have. A couple of people have suggested that including Stephen Watson, I just haven't found any solid info on that method yet. We are moving in August or early Sept so I won't be starting the mod until after that. (Got a 4 car garage in my future)
I have been in search of that adapter for close to 4 years now. GM quit production of that adapter in late 1998. So I tried calling dealerships across the us. So far I have called in excess of 200 dealers and have yet to find one. I did come across one in 99 but it was cracked almost in half. My next idea is to buy a 91 k-30 crewcab. (the only vehicle they ever came in) steal the 4l80 and 205 combo and replace it with a 400-205 or 700-205 and send it down the road. I have only come across 3 of those trucks since i started my search and they were all in the 7-8k range. Maybe you will have better luck than I have had. Brian
I didn't realize this was a quest for the "Holy Grail" of adapters. It does make it interesting though. Thanks for the info. Where was the cracked one from?
Yeah, I thought the 465/203 adaptors were the hardest to find. /forums/images/icons/tongue.gif Since they were only made for one year also, I have already found 2 of them. /forums/images/icons/wink.gif
Man, this 4L80E/205 adaptor is really beginning to bring out the stress in the hunt for one. /forums/images/icons/tongue.gif
The cracked one came from a wrecking yard in el paso tx. I was so stoked to get it in the mail, I had a full woodrow for almost a week. When i opened the box, my woodrow turned into a weaping willow. It sucked big time. Advanced adapters does make a 4l80e to 205 adapter, but it sells for around $600 and uses the 205 from a 350 or a 465 /forums/images/icons/frown.gif not the beefy 205 for the 400, so it kind of defeats the purpose. I guess we will all have to wait till more 91 crew cabs are either canibalized or have found there way to the metal graveyards to find the adapter from hell...
SO you actually have a cracked one?? Is it for sale if you do?
sorry, I sent it back. it cost me $150 and was almost cracked completely in half.
