T-19 codes for ratio's?

Post #1 by broncr » Tue Feb 19, 2019 12:09 pm

I did the T-18 to T-19 swap, some years ago. It was one of the best/easiest things I ever did to my Bronco. The synchro'd 1st is wonderful. Unfortunately, the only one I could find in the entire region was one with the 4.02 first, which is just a tad high for my rig/gear/tire combo.

I found a seller with several T-19's. I'm waiting for a call back - I know - it's as simple as putting the trans in 1st, and counting the number of rotations at the input to get one on the output... but a leap of faith in this case.

Is there a way (casting number) to tell which is which, amongst the three available 1st gear ratio's? My research, so far, tells me that the 5.1's are more common in the '83 & 84's, but that's little comfort.
'82 FSP Bronco. Just about every mod ever mentioned. ( Too much to list - or remember...)

You have no choice but to measure. wrote:It was introduced in Ford trucks in the 1968 model year.

Three gearing options were available for the Ford T19. The T19 was available with a 6.32:1 first gear. These were only in rarer Ford 500-800 series HD trucks. The very most common T19 available in Ford applications was the T19A with the 4:02:1 first gear ratio. For two years (documented from 1983-1986+) there was a Ford T19 option with a 5.11:1 first gear. All ratios listed had a synchronized first.

We've learned that the 1983 to 1986 Ford T19's, as installed behind the 460 and diesel typically had the 4.02:1 first gear in a 2wd application, or a diesel 4wd application. However, 5.11 versions are reported also for these. The 460 4wd truck got the 6.32:1 first gear, purportedly from 1983 to 1986 F250's.

The T19 transmissions are equipped with dual PTO ports. An individual may find the cast numbers of 13-09-065-911 or 13-09-065-905 in Ford T19's.

I'm quite certain that a tag might exist to define what gear option of the three was used, but only Numbers Dummy from the F truck forum would know.
