We hear of Allison fluid leaks every once in a while, and have recently experienced one ourselves. Most of these leaks result in automatic transmission fluid dripping off the bellhousing area of the transmission. An input shaft seal problem probably comes to mind first, but as we've learned,...
Both versions used GM’s 8V-71 engine, arranged in a “V“ drive configuration. Transmission was a 4 spd Spicer unit. Overall, these buses enjoyed a good reputation; they exhibited GM’s excellent build quality at the time and the extended wheelbase 40 ft models rode very ...
8] It is important that after initial installation you fill the line slowly, high speed air purge could cause damage to the rotors. 9] Test the system for leaks. 10] Check the strainer for swarf or foreign material, after the first 200 litres check periodically, particularly if the flow ...
ATSG Checkball Book The Allison LCT-1000 transmission was found in the heavier GM, Chevy, and GMC truck models from 2001-up with the 6.6L Duramax diesel or the 8.1L gas engine. These transmissions are also found in the larger Isuzu trucks with the 7.8L Diesel. The T-1000 Allison was ...
That’s why the systems now only have 8 and 4 cylinder mode. Reply Axel says: February 28, 2018 at 12:43 am I got as high as 23mpg on the highway in my ’89 K1500 with 350ci and a five speed manual. How about if they just let us have a manual transmission agains...

the basic test apparatus shall consist of a housing for retaining the test fluid, and position- ing the oil seal(s) on a rotatable shaft supported by an externally mounted spindle. 2.1 the spindle drive shall be capable of cycling and maintaining shaft speeds within +5%. the variable speed ...
The lock-up torque converter (sometimes called the TCC for torque converter clutch) was necessary with overdrive because if a non-lock-up torque converter is operated below it's 'stall speed' for long periods of time, the slippage will heat the transmission fluid, possibly excessively. But lo...
8.The control system of claim 6 wherein said threshold is determined based on said measured transmission ratio and a shift torque. 9.The control system of claim 6 wherein said slope is determined based on a derivative of said measured transmission ratio. ...
which in turn has the advantage of increasing the speed of response when an oil flow is needed. For example, when used in the oil feed to a torque converter in an automatic transmission, the torque converter remains filled with oil even after several hours of non-use; this has the advanta...
