None - GM sold Allison Transmission to The Carlysle Group and Onex Corporation in 2007.
No, it's just the case.
gm bought allison in 1987
It is a 4L85E transmission. The 4L85E is GM built, not allison, 4 speed automatic transmission.
No it does not, Allison transmissions are used in gm's pickupsAllisons are in the Ford Powerstroke setup as well.
No GM does not own any part of Toyota.
Official word is no, You need to calibrate for a 6 speed, Hard to get the GM dealer to agree to it. Allisontech
2006 and up . Gm 3500 hd 4x4 z71 with the duramax diesel and Allison transmission.
From what I understand GM still owns the Pick up truck plant in Baltimore,and the Hybrid electric operations. the remainder is no longer owned by GM. Allisontech
No. GM does not own any part of Chrysler.
The transmission fluid is called synchromesh its a special fluid was only available at a dealer now penzoil makes their own. The gm part number is #12345876 I believe.
As far as light duty (Class 1 - 4) trucks go, just General Motors. Ford uses their own transmissions, and Dodge uses the Aisin transmission. If you look into medium- and heavy duty trucks, several manufacturers have the Allison automatic transmissions as an option (for example, you can get them with the Ford F650 and F750), but these are quite different from the transmissions used in GM light duty pickups.
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.
