The Chevy Astro van was available with different transmission options throughout its production years. Early models of the Astro/Safari vans, up until 1989, were offered with either a 700r4 4-speed automatic transmission, a 4-speed manual transmission, or a T5 5-speed manual transmission. However, the manual transmission option was discontinued after 1989. Starting in 1994, the Astro van moved to electronic controls for the automatic transmission, specifically the 4L60E.
Therefore, depending on the specific year and model of the Chevy Astro van, it could have either a 700r4, a 4L60E, or a T5 transmission.

What is needed for a 4L60E swap?
Because the 4L60E is an electronically controlled overdrive, it demands electronic watch-keepers like a stand-alone controller, TPS input, and converting the electronic signal into a useable speed display. Then there are the mechanical bits like the need for a shorter driveshaft and some floorpan mods.
What GM vehicles have a 4L60E transmission?
The 4L60-E is found in nearly every GM rear-wheel-drive, including the C/K Truck, Sonoma, Jimmy, Tahoe, Yukon, Astro, Safari, Suburban, Bravada, Firebird, Camaro and Corvette. 1998 Bellhousing for 300mm converters and 5/8″ deeper. 1998+ Firebird and 1999+ C/K Trucks.
Are 4L60 and 4L60E the same?
RE: What is the difference between the GM 4L60E transmissions? All 700r4, 4L60, and 4L60E transmissions have the same gear ratios. The major differences are external. Electrical hookups, speed sensor hookups, calibration, and converter stall are the main differences.
Do I have a 4L60 or 4l80?
The 4L80E can be told apart from the 4L60E by looking at their transmission fluid pan. This is because the 4L80E has a pan that is oval in shape whereas a rectangular pan is featured by the 4L60E. Another disparity between both devices is the number of bolts used to secure the transmission to the engine.
Are all 4L60E the same?
None of the ’93 -’97 4L60E’s are directly interchangeable, except ’93 and ’94 and ’96 and ’97!!! Here’s a list of yearly differences that will show you why. Yes, some years will fit in others and may not even throw a code, but there will be an issue in the long run.
What years did they make the 4L60 transmission?
The key distinction of the Later 4L60-E (1996-2010) from the Early 4L60-E (1992-1997), 4L60 (1990-1992), or 700R4 (1982-1989) is the six-bolt “hex” rear output or tailhousing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tailhousing.
What transmission is in a 1999 Astro van?
Vehicle is a 1999 astro van 4.3l 2wd with obviously a 4l60e transmission.
Will a 4L60E replace a 4L60?
While the 4L60 is controlled with a TV cable, the 4L60E gets its own control from a computer. This difference can be sorted when the latter is placed in the position of the former; for this reason, all that is needed is for you to get a new transmission controller so that you can override its control mechanisms.
How good are 700R4 transmissions?
GM continued to improve 700R4 throughout its lifespan, and by 1987 the transmission is said to have reached its full potential. Enthusiasts often consider the batch of 700R4s built between 1987 and 1993 to be the most durable and most sought-after.
What transmission does a Chevy Astro van have?
Astro/Safari vans were available early on with either the 700r4 4 speed automatic, a 4 speed manual, or the t5 5 speed manual transmissions. This lasted through 89 when they stopped offering the manual transmission. In 94 they moved to electronic controls of the automatic with the 4L60E.
