Barg Warner I think it's called from memory. It was hard to find the part numbers and any first-hand experience installing them. I bought those solenoids direct from the gear box manufacturer. Well I ordered the solenoids based on the supply website, and they worked great! We offer Diagnostic trouble code retrieval procedures as well as descriptions and diagnostics for these transmissions. The problem was getting worse and I had to fix it. They also have the larger 5.
The solenoids through the dealer are an outrageous amount of money! I'm asking because I seen a 97 mitsubishi diesel fuso and the trans looks similar to the aw450-34le but I read they were not offered until 99. Fortunately the a442f is still a common use gear box for light trucks in Japan so you and get them cheaper direct. This transmission was first introduced in 2004 in Mitsubishi Fuso trucks, Isuzu trucks introduced in 2006 and called the A465. Planetary part number from Isuzu: 8-97257013-0 and Isuzu part number for sprague is 8-97257014-0 Cause: two possibilities; one is both speed sensor 1 and 2 are not working, thus Tcm doesn't know truck is moving should be trouble codes set or debris from internal failure or if replaced unit already may be from cooler etc has gotten into valve body and stuck shift valves and so on. We offer Free transmission diagnostic help for Aisin transmissions via E-Mail. My Cruiser: Same issue I just fixed.
They used a fine gear system for the injection pump, camshafts, etc, and although that makes them slightly quieter, they are prone to stripping the injection pump gears. And found yourself wondering how to retrieve transmission trouble codes without the use of an expensive factory type scanner or software? Cause: this scenario usually means the throttle cable from pedal to injector pump linkage is loose. Just follow what Astr did for his transmission build and you will do the same thing. That was probably the original sensor with 130k miles of wear on it though. Car only done 145000 km but solenoids had locked up due to sitting in the garage for years unused. I haven't seen anything on the pump itself to prove that though, just the rpm sensor and the fuel rack position sensor.
I just want to share this on the forum, and hopefully make it easier for the next person to find. Do the transmissions look that much alike between the years? The part numbers I found on the forum did not match what I ordered from the transmission supply website. Cause: one of sensors is dead, Ckt open etc. I took the pan off the transmission and checked one solenoid. Well it seems some particles got into the solenoids and clogged them up.
My 1993 80 series with the A442f transmission was sometimes not shifting, flaring, skipping 2nd, and not downshifting. Fueling mods to get more power will speed up this wear drastically and I know you want them 2000-2004 trucks were changed to a coarse gear system which fixed the problem. If so,what should I look for to make sure I get the compatible transmission? Have you needed diagnostics help or information for Aisin Transmissions? It is a completely different engine. Does anyone know if there is a specific vin code we could look for to make it easier when searching for a donor vehicle. .
Mitsubishi trucks also have stand alone cooler and fan, switch, which can be failed fan, switch etc and will cause severe overheating! The 4M50 and 4D34 do not share block castings. Its also very common someone has installed lines at filter head, backwards thus deadheading the cooler flow thru unit. Cause: low Sprague inside transmission has or is failing. . . . .
