If your code is an A, for the three speed, then someone has done a swap. (Probably. It might even have been done by the dealership.) If it's the NP435, then reverse is back, next to 3rd rear. If it's one of the Warner units, then it will be forward, tword the dash, near 4th gear.
T98 and T18 share the same case, except the later T18s have T18 stamped in the drivers side, earlier cases have 1301-??. T19s also share the same case, but those came out much later, and are stamped T19. Basicly, they are all the same, with only small variations in gear ratios and oiling

I think(someone correct me if I'm in error) that the coolant lines you see running from the radiator to the tranny carry transmission fluid from the tranny to the radiator where it is circulated through a built in cooler in the bottom of the radiator. This is integrated in the radiator but is a separate tank from the radiator core. Hope this helps. Steve

59 You are correct for 99% of the time. While I don't read every post in depth I scan every one here and on 67-72 forum. Every now and again the subject of a coolant tranny comes up. The factory C-O-M that I once had ran tranny fluid in the lines.
One thing that I have learned, about the time you think you know everything about a Ford truck subject, someone comes along and proves you wrong.
Wow! You guys all seem to know your stuff! Yep, as 66beater guessed, someone has
swapped the engine and trans in my '66 F100. The engine code on the plate doesn't
match the engine either. I checked for a number on the trans and found the code.
It reads "C9838". The shift pattern has reverse over to the right and down, away
from the dash and closest to 4th. The shifter **** shows 1st at the top left of the "H"
and 4th at the bottom right of the "H". Does anyone out there know what kind of
transmission this is?
Thanks! Paul in Seattle
Hi 99150! I googled NP 435 and found that the case numbers do start C9XXX, so I
am pretty sure it is the New Process 435. Does anyone have an opinion about how
well the NP 435 stands up to more powerful engines than the 352?
Thanks for your input!

Both the new process and the Warners are stout transmissions and should be able to handle a lot of torque. Thease are slow shifting Trannys and that also helps give the syncros time to work.
an easy as pie way to tell the difference between the Warner gearbox and the NP435....where is reverse...if its over right and back...NP435...if its over right and forward....thats Warner gearbox....I got what I thought was a NP 435(door tag was N) and discovered that it was the Warner box....if I had known....hehehe.....not easy pulling a trans in the wrecking yard by yourself....
IMHO....the NP box is superior....got one in my 2wd beast....almost 225K....never opened up....thats after many a load of wood and camper and car trailering....nice and tight still....
I just put a '68 390 in my f100 and i was wondering the same thing paul was... How much horsepower does it have with a 2 barrel carb stock?
Thanks

Wow! This'll be a first....
In my case ('65 F250 352w/ COM), I most certainly had a COOLANT line running from both block drains(a Y-pipe) to a tranny mounted coolant-to-ATF intercooler. The return line went to a "T" in the lower radiator hose. This was a factory setup....that was stupid, which is why most all of them are converted to a more conventional setup as stated above.
My 66 390 ( newly rebuilt) automatic still runs on the hot side of the gauge when pulling* my 3800lb vintage trailer. I have a newer aluminum radiator with dual fans…installing a g3 altenator, new thermostat 160…all in attempts to keep the truck from running hot while pulling. Would an aftermarket trans cooler be a good idea as well? And if so, which one should I order.
im about ready to give up on this truck that I really love. I bought it to use as my “vintage” tow vehicle about 10 years ago. Extremely nice looking truck in original paint, and interior. Custom cab. The altenator belt was missing once I got her home and we were able to check things out. So frustrated after doing everything I have done to this truck to make it work. I was pulling on flat Hwy when this happened…
Do you have a shroud on the fan? I don't think the 160* thermostat is going to help. It will open sooner but once the engine has been running a while, it is still going to be hot. Is your gauge accurate? I would install another temp gauge to see what it's reading and then try running without any thermostat to see what unrestricted flow does.
Wow, risen from the dead, eighteen year old thread.
How is the temp when you’re not pulling the trailer? Can you install an accurate temperature gauge? My truck has always shown to run towards the hot side of the stock gauge, summer or winter, even after re-coring the extra cooling radiator, adding shroud and a seven blade fan. Does your truck have the extra cooling radiator?
I’m told the original gauge is known for being inaccurate. I drive in the very hot San Joaquin Valley of California. I’ve learned to just ignore that needle parked nearly all the way to the right toward the H. Is the needle all the way into the H, or just to the left of it?
That said, being the cautious person I am, I’d not be pulling a 3800 lb trailer with a half ton, automatic truck - though many others do so.You’re also probably running your AC at the same time, no? This is probably exacerbating your problems.
