Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
Most likely it is fourth gear and reverse. Any good trans shop that works big transmission will be able to address the rebuild. I have an A3 with the same issue, 8 bell housing attach bolts and it's on the ground. May repair it myself if I find the time.
Yea, your right, it's fourth. He replaced the OEM tranny with a used one and it has the same problem. I get the original one with it, so may try to rebuild it myself.
Knuckleheads had nothing to do with the MO. Once again Allison OK it.
Again your misrepresenting the facts. That MO is OLD ! There is no longer any engine oil that is cleared by Allison. It is obsolete. You finally mentioned that the engine oil was to be used "off-road" only. After I called you on it. As to getting upset about anyone correcting me, if you have facts I will listen. I have in the past. I just don't like misinformation being spread around like it's "Gospel" when in fact it's your "opinion" . As for not bringing any information to this, are you kidding ?!?!
Do you want to totally remove it ? Or just disconnect it for a while ?
I recently replaced my steel hood with an NOS fiberglass hood. What a difference! The fiberglass hood looks substantially better and is much lighter when raising and lowering. I don't have insulation on the fiberglass hood, but I can't tell any difference in noise levels from when the steel hood with insulation was on the truck. However, I have some caveats regarding the NOS fiberglass hood. The NOS fiberglass hood came with new hood hinges which were well painted. However, the new hinges were tighter on the pins than the originals, although they moved freely. Within two weeks in the rain, both hinges rusted and seized up. The paint on both hinges completely disappeared, like it was watercolor paint. Two weeks later and both hinges were bare steel with no sign of green paint, and rusted solid. I had to remove both hinges and replace with my originals from the steel hood. Another caveat is that the rubber hold down straps that came on the NOS hood failed within one month. Although they both looked brand new, both broke into two pieces. Again, I had to use the originals from my old steel hood, which are still in excellent condition despite being many years old. The ones on my NOS fiberglass hood were junk. This was an original NOS fiberglass hood in the original packaging, not one of the replicas that are being sold. If anyone else is installing one of the few remaining NOS fiberglass hoods, beware of the hinges and rubber hold down straps.
I'm replacing my (pipe size) A3 wheel valve stems with these:
Was your truck struggling to shift, and when it did, slam down in gear? If so, I had the same issue a couple of months ago. I never fully figured out the issue, but did make some headway with cycling through new ATF, as well as an interior and exterior filter change.
The behavior you outlined is typical when motor oil is still in the transmission. Especially downshifting when slowing down or stopping. Switching to Dexron III eliminated this in my A3.
When I drained the oil the first time, it seemed to be pure ATF (albeit burned). Is there a good way to clean the system without draining multiple and filling times?
I would take it to your local Allison shop. The Penn Power Group here quoted me $250-$300 to flush the system and fill it with Dexron III. But if you don't want to spend that money, a forum search will spell out the DIY flushing process for you.
