Trans swap?

blackdog
I picked up an 84 longbed today and thereby ended my quest for a seat...yeesh! If I were still in Oregon I'd have found a dozen for nothing. Anyway, this truck has a standard, which should be a t18 because it's a four on the floor and not a heavy duty, right? Could I cut a hole in my floor and bolt the t18 onto my 302, which currently has the AOD? My truck will just be used for cruising, no trips longer than an hour or two each way, and will never haul anything except a ladder and some paint. Thanks in advance for any input, have a safe super bowl and enjoy the game! ... if that's what you're into

What engine is in the donor?

The bellhousing patterns are the same.
You will need to disassemble the dash to change the pedal support, and drill the firewall for the master cylinder to pass through.
You might want to swap out the automatic style steering column while it is out for the pedals.

Auto/manual starters do NOT interchange.

Flywheel to replace flexplate.
Afaik 300, 302 & 351 all have different balance in this era.

I think only the 460's and diesels got the T19, so it should be either a T18 or NP435.  But both of those are stout transmissions, and if your new truck has a Windsor or 300 six then it'll bolt to your 302.

And, Jim is right-on regarding the other things.

Looks like the donor truck has a 300/6. And good point on the flywheel interchange.

If the 302 in his 86 is the original, it will require a 50oz 164 tooth flywheel to use with the manual trans from the '84. Can't use the 300/6 flywheel for the manual swap to the 302.

Other than that, he should have everything he needs between the two trucks.

I kinda 'assumed' the donor to have a 300 from the second post, but I've made the mistake before.

Do you know if the 300 starter is the same as the Windsors?
I know the bell is the same, but I know nothing about ring gear diameter or number of teeth.

Yes, 300 starters are the same as the Windsors.  From our new Starter Interchange page:

Couldn’t a 1984 four on the floor also be a 4 speed overdrive? Going from long bed to short bed and auto to manual you will most likely need a correct length driveshaft made.

Once you start swapping anything flywheel related around with a 302, it can get confusing pretty quick. With a little searching, it doesn't take long to find old threads where somebody is asking why is their engine vibrating after a swap of some kind. There is the 302 balance difference which changed from 28oz to 50oz sometime in 1982, but then there's a difference between car flywheels (157 tooth) and truck flywheels (164 tooth). Add on top of that the 300 and 351 flywheels also fit but are not balanced for the 302, then there are all kinds of possibilities for mistakes.

There was an episode of Roadkill last year where they installed a 351 in a Mustang and went to fire it up and the starter didn't touch the flywheel (because it was the wrong size)...lol. It happens.

The flywheel for a 300 has a zero balance flywheel so it will not work for anything other than a 300. The tooth count on the flywheel has to match the bell housing of the transmission. There were car and truck C4 bellhousings with the truck having the larger bellhousing therefore a larger flywheel with more teeth on it. I believe you should verify with a transmission expert or at least someone knowledgeable about the correct tooth count and correct balance of the flywheel that will match your chosen transmission.

Thanks for all the input, guys! Only problem is that the steering column in the manual is locked up but one found a website that sells refurbished columns for around $600. Inwas going to replace column on the auto anyways cause the gear levers are loose as heck. How can I tell if it is a t18 or the other? By appearance or number?

This post was updated on .
The Borg Warner T-18 has a cast iron lid, while the New Process' lid is aluminum.

You can look on the Novak Transmissions website for more details like casting numbers, ratios and such.

If the truck is all original we can ID the trans from the certification label on the driver's door jamb. You can post a picture of it, or just tell us what digits are under the TRANS section.

Looks like JH4 under trans or "B".  They're kinda offset from where they should be. Made in canada apparently

Just by looking at pictures of the two, I believe mine to be a t18.

Ps steering column isn't "locked up" just ignition cylinder/tumbler so I should be alright to use it

The JH4 is the paint/interior/color code. The "B" would be the transmission:



Looks like the 4spd with OD. Is the shifter knob still on it? What does it show?

According to Gary's Transmission page, the 4 spd OD is a Clark unit.

Maybe have a look at the info in the link below, might help ID the trans...

The shifter has the encircled "D" for od.. will this still be able to bolt onto my 302 with the 50 oz 164 toothed flywheel?
