Fits 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, and 81 cars. You should re-use it ever time you replace the oil filter. This is because the 1955-'57 Chevys had a perimeter frame and leaf rear springs. It was used in various , , and models from 1964-1969. The lower terminal is for the kickdown solenoid. Buick also used Isuzu-manufactured manual transmissions.
Use a 26 spline input, hopefully with an oilseal and you could go 27 splines on the mainshaft if its a street car, but it will be stronger with 32 splines on the output. Exact fit for all first and second generation models with Pontiac engines. Verses the 32 splines of the 6L80. The shoe heel impression is where the filter picks up fluid and the pickup is shaped just like a shoe heel see photo above right. These are the correct bolts to mount the valve that your oil filter screws on to at the engine block.
This is essentially a Chevrolet transmission adapted to suit the particular requirements of these brands. Works great on all Pontiac engines; 326, 350, 389, 400, 421, 428, 455, etc. . The default no-power position is low stall. While some parts swap between the 6L80 and 6L90, there are differences to watch out for, such as a longer case length for the 6L90 as well as larger output and spline count.
The shift pattern was P-R-N-D-L. There were multiple versions of the Dynaflow throughout it lifetime- but the Turboglide is most closely related to the 1956 and later Triple-turbine Dynaflow , Flite-pitch Dynaflow and the later Buick Turbine drive. All Replacement brand items are backed by a 1-year, unlimited-mileage warranty. This powerful magnet will hold any metal particle the the oil filter fails to capture. The stator blades moved from high to low position by an electrical and a stator , controlled by a switch on the linkage. This version does not have the pre-installed inner baffle.

The 1957 trans is visually different from the later trans in that it has a pair of cast transmission mounts on its bellhousing: large flat surfaces cast at 45 degrees from the horizontal on the underside of the bellhousing. The difference between the Turboglide and other automatics except for the Dynaflow is that the Turboglide has a torque converter with three separate turbines in the one converter case, each of the three turbines are geared to the output shaft with different reduction ratios. First use was with 1996+ Vortec 4. Above average but will have some dents or dings. In most cases there is no sense in using an M21; there are no premium quality gears, and by changing the input and cluster, you get an M20 which has a deeper 1st gear and is better suited to street cars these days. The first turbine had 2.
This feature was not used on the Pontiac versions of this transmission. This makes it fairly easy to identify. It basically has little to no performance potential and is not considered to be a particularly reliable or strong transmission. The stator blades changed pitch by an electrical solenoid and a stator valve, controlled by a switch on the throttle linkage. You may notice that most used parts are not priced because our used parts inventory changes daily. Use oil-pan shape to differentiate automatic transmissions with the same bolt count.
First appeared in the mid to late 1960s with the Super Turbine 300. In 1996 the 4L80E has some design changes in lubrication circuits. These Performance Automatic deep aluminum transmission pans will increase fluid capacity, making for more efficient cooling. Exact size, shape, and specs as ram air and super duty. This was followed in 1958 by a triple turbine Dynaflow. Aluminum also promotes faster heat dissipation for further cooling of your transmission.
Remember these are over 50 years old and will not be new or perfect. You must be very careful when replacing gear train parts in late design 4L80E. All of the Turboglide trannys function the same with only detail changes between them to improve reliability. The one you will receive will look similar to the one pictured. From 1967-1969, the Super Turbine 300 was also available on the sporty with the overhead cam inline six 230 and 250 cubic inches or small V8 engines 326 and 350 cubic inches. If the cover is removed, the pitch of the gears can be seen.
