How can you tell the difference between a 6L80 and 6L90 transmission?
What is the difference between 6L80 and 6L90 transmission? The main difference between the 6L80 transmission and 6L90 transmission is the strength of the internal components. The 6L90 transmission case is 1-3/8” longer, which provides extra room to house two additional pinion gears (6 total).
How long will a 6l90 transmission last?
It is validated to achieve 200,000 miles of operation in typical applications.
Does a 6l80 have to be programmed?
This transmission is an electronically controlled unit with an internal TCM (transmission control module) that must be Reprogrammed before operating the vehicle. Failure to do so will destroy the transmission.
How long will a 6L90 transmission last?
Is the 6L90 a good transmission?
Is the 6L90 a good transmission? The 6L90 transmission is not a terrible transmission. In fact, it is a high-performance component capable of handling up to 700 horsepower. Along with the 6L80 model, this transmission powers the best cars and trucks that GM offers.
Why does my car jerk when shifting gears with an automatic transmission?
Automatic transmissions that shift hard, jerk or shake during a shift change may mean your transmission fluid needs changed or fluid level is low. In manual transmission vehicles, abnormal gear shifts could indicate damaged gear synchros, worn clutches or other, more severe issues.
What causes an automatic transmission not to change gears?
One reason why an automatic transmission isn’t shifting into gear has to do with the fluid. If it’s not at the right level or the incorrect type has been used, then it’ll affect the gears. Another big reason has to do with the ECM possibly going bad.
Can I swap a 6L80 for a 6L90?
6L80 converter will work with a 6L90. The TCM will have to be reflashed to a 6L90 at the dealership first,then it can be tuned normally.
Which is 6 speed transmission does GM 6L90 use?
The 6L90 is a heavy-duty version of the 6L80 six-speed automatic, with a strengthened input gearset that has two additional pinion gears (six in total) and a strengthened output gearset that uses wider gears than the 6L80.
Do you need a dipstick for a 6L80 transmission?
Plate-type oil-to-air (OTA) transmission coolers must always be replaced. Entire transmission cooling system must be completely cleaned, hot flushed, and flow tested. 6L80 / 6L90 transmissions do not typically use a dipstick. Proper fluid level is achieved when fluid begins to drip from the Level Control Plug opening.
How does the transmission work on a 6L80?
The transmission and module are assembled together, so no additional steps are necessary during vehicle assembly. The 6L80’s 32-bit transmission control module (TCM) monitors transmission performance and compensates for normal wear in components such as clutch plates, so transmission performance remains consistent for the life of the transmission.
What kind of transmission does a GM Hydra matic use?
The Hydra-Matic 6L90 (production code MYD) is a six-speed automatic transmission produced by General Motors for use in rear- and rear-biased all-wheel-drive vehicles with a longitudinal powertrain
