hello everyone,been reading here for so long feel like I know everyone.I've done searches and have found lots of info on the t-18 but have yet to find out what I'm wanting.
I have a 2wd t-18 out of a 86 f-150 300 six,I want to mate it to my np205 t-case that is currently bolted to my c-6 in my 1973-9 f-250 that started life as a highboy.
a fellow fte member let me know I couldn't use my auto adapter,thanks amtek.
so what parts do I need to get these 2 together?output shaft,diff adapter,diff trans?
thanks
You need the output shaft for a t-18 4x4 set up as well. It would be far cheaper and easier to just buy a t-18 from a 4x4 truck and use it. I use to have a t-18 adapter and had it been sitting around for years but it has been moved on now. You may even just try to find a 435 trans and run it out of a 4x4 truck of course.
I know there are two different lenght adapters for the C6 set up but I am not sure if this applies to the 4-speed trans or not. Then you have the all by it's self 203 adaptor.
thanks,i got the trans as a bonus when junking a truck it's in good shape also.I was going to pull it apart and put a bearing and seal kit in it so replacing the rear shaft is not a problem.is that the only diff between the 2,output shaft and adapter?to tell the truth I would like to have a zf 5 spd but I've got to spread the money around on my truck.I still have a few other big projects planned.the reason I want the stick is beacause my truck is a 3/4 ton 4x4 with a 302 and 35's,the low leaves something to be desired.changing the motor is not a option,gonna stay with the 302,got some stuff in the making for it.
I'm not a rock racer or mud bogger but do wheel often and would like a better low range than what the auto has.
i could probably find the parts i need just don't know what they would be,hoping to get a jump on this so I don't have everything apart for weeks or months searching.
oh yeah and probably need the little coupler sleeve that connects the trans to case too huh?so three things right?and of course the bearing and seal kit.
thanks again ya'll
I've seen complete 435 trans with a 205 case for $200 to $300. By the time you by the adapter and the out put shaft you may as well buy a 4x4 trans because the output shaft and adapter will cost more than the trans itself. Most people will sell the t-18 or 435 trans by them selves and sell the case seperate. Now your looking at well under $200 for a trans with the correct adapter. PM me and I will direct you to a few other sites that you can search around for what you need.
The small block ZF is a tough one to find. I have had two of them and sold them. I paid $100 for one and $150 for the other both in good shape. I was very lucky to find them. I now have a big block ZF from a 460 to put in my 78 bronco which will be getting a 460. It's under going a frame off resto.
Now that I think about it I know of a parts truck that has a small block 4 speed set up in it. The 4x4 truck had a 300 6cly in it. It's a 78/79 model 3/4 ton. If you want I can try to get you a price on the trans. bob
thanks for the offer but I've got a few pals that work at a couple yards can get me stuff cheap.
I have found a 4x4 t18 with a 205 but it has a hole in the side of it where it blew a front driveshaft and then it was driven and messed up pretty bad.I haven't seen it to verify it but i can have everything but the t-case.it's a little bit of a drive to get there and I wanted to know if the parts interchange between the 2wd and 4wd.
I'm only gonna have 20 in gas and the price of a seal and bearing kit in it.
why the 435?the t18 should be plenty strong enuff.and the diff in 1st really isn't a factor for me.
Either the t-18 or the 435. It's just habit to type the 435 all the time and I see more of them for sale than I do t-18. The broken trans will have the output shaft you need and everything should swap from one to the other.
Can't go wrong for the price. I can always find time to pick parts up but I don't always have cash for parts.
