2006 blue bird cat engine,allison transmission has range inhibit and no shift
An Allison 1000 transmission will not bolt up to a Chevrolet 454 you begin engine. The Allison transmission is much larger than the Chevrolet engine housing can handle.
AnswerThe Allison 1000 Automatic Transmission Automatic Transmission, 5 speed 1000 Initial Fill is 7.4 quarts[2] Automatic Transmission, 5 speed 1000 Total Fill is 13.0 quarts.DO NOT drain the fluid if only the transmission spin-on oil filter is being replaced.
The Allison 1000 which is mated with the Duramax diesel
allison 1000 if it is before 2006 (5 speed). in 2006 they switched to the 6 speed allison 2000
The Allison 1000 transmission typically holds around 6 to 8 quarts of transmission fluid, depending on the specific model and configuration. When including the torque converter, the total capacity can range from approximately 11 to 14 quarts. It's important to consult the owner’s manual or manufacturer specifications for the exact capacity for a particular vehicle.
Yes. All Duramax and 8.1L gas engined 2500 or 3500 series pickup trucks with an automatic transmission have Allison (1000 series) transmissions. Larger trucks (2500 series and up) also use the Allison transmission for their automatic offering but it is a different series that is similar to, but not the same as, the 1000 series used in the smaller trucks. Prior to the Duramax (introduced in 2001), GM did not use the Allison behind their diesels (6.2L and 6.5L) in pickups.
To perform a pressure test on the Allison 1000 torque converter, connect a pressure gauge to the test port on the transmission. Start the engine and allow it to reach operating temperature, then shift the transmission into gear while monitoring the pressure readings. Compare the observed pressure to the manufacturer's specifications; if it falls outside the acceptable range, it may indicate issues with the torque converter or related components. Always follow specific service manual guidelines for detailed procedures and safety precautions.
The price varies, but it should in the range of $1000-3000 + transmission.
They all use automatic transmissions anymore. For Type B, C, and D school buses, the Allison automatics are most commonplace. Usually an Allison 1000 series transmission. For Type A school buses, it'll depend on what the chassis manufacturer typically uses... a Type A school bus on a General Motors chassis which can still be reasonably expected to be in service will have, depending on model year, a 4L80E, Allison 1000, or 5L70E, or 6L80E, for example.
It looks like 2005 was a transition year between the 4L80E and Allison 1000 with 6.0 engine. Sounds like 4L80E was typical, but easily upgraded to Allison at time of ordering, but also depending on packages and equipment. If it has an external filter it is the Allison, otherwise it is 4L80E version.

Depending on year and model, they can be either mechanically or electronically controlled. They're true automatics - they use a torque converter, unlike an autoshift, which is an automated manual. They're available with 5 - 7 gears for the 1000 - 4000 Series, although they do have a ten speed, twin countershaft transmission.
