Don: Down through the years TA has been given a bad rap, and most of that was the fault of IH. IH should have put alot more development dollars into it much sooner than they did and eliminated the freewheeling on the low side. If you look up the thread at what Nebraska Cowman has said, he covered it all. Some of the first operators tended to get wrapped up in what they were doing, forget they were in low range, start down a hill, the tractor starts to free wheel, and bingo they shift into high, but not before tractor was rolling faster than the particular gear in high. My dad was famous for this, we never seemed get him to remember the free wheeling, and that 300 was the one we had to rebuild prematurely. We trained many young lads after that, and it never seemed to be near as much problem. It has always been very important to keep TA adjusted properly and to shift it quickly. I really can say nothing but good about TA, we used and used it a lot. If it suited we worked it on the low side all day. Some will say never shift it on a hard pull, they could have fooled me, and my 3 diesels were proof of that. I remember one night hooking 1066 out front of a disabled tractor trailer loaded with grain. The drive shaft was broken and it was beginning to rain. that tractor trailer had to come out of there or it may have been there for days. I started out in 4th low, low on TA, at point tractor stopped lugging hard I could feel it start to spin, I put TA into high to keep tractor lugging hard, soon as it would start to loose rpm's back to low. I did that about 6 times up that 1/2 mile grade, pulling 75,000# of dead weight. Today, TA is getting another bad wrap, that being caused by folks doing back yard rebuilds. Yes, folks that are not qualified to decide what should be replaced. Most of them should just go for trade in on a professionally rebuilt unit.
