2002 Chevy Express Van 5.7L automatic/ 40000 miles

:disappoin I'M HAVING PROBLEM NOW...THE TRANSMISION WON'T SHIFT TO 3RD AND "D" THAT'S FOR SURE AND NO TROUBLE CODES OR ENGINE LIGHT. NOW HOW DO I FINE THE PROBLEM??!
PLEASE ANY HELP??!
THANKS MARTIN

What transmission?
How is fluid level and condition and filter?
Any repair or transmission or engine service?

To test or check the transmission you need to get it on a good engine /transmission capable scanner.

Read out transmission slip and shift data and check for codes.

Post back any codes engine or transmission.

Hi,
thank you for you reply. Well the transmision is 4 speed automatic 1-2-3-d, no overdrive. The oil level is good and clean, but i will try to change the oil today. I got the van just two weeks and take it because low milage and it drove just fine and last week i notice higher engine rpm and then test drive with open cover inside the van and also used scanner set to check engine rpm and drive 60 mph on freeway and engine rpm got little over 4000 rpm witch seems to be high for v8 engine. Anyway i put it on "d" and goes 1-2 and maybe 3rd that i cant feel so "d" das not work for sure. I check all wiring to the transmision and its all o.k. There are no leaks all is like new.

You need to get it put on a transmission capable scannner and read out shift data and codes.
If any codes post back codes.

, no overdrive.
FWIW your trans is an overdrive unit. It's the 4L60E unit:

From Wikipedia:

700R4 / 4L60 / 4L60E / 4L65E

The Hydramatic 700R4 was introduced in 1982 for use in Chevrolet/GMC vehicles.

In 1990 the 700R4 was renamed the 4L60.

1992 was the last year of wide spread usage of the 700R4 (4L60).

1993 Camaro, Corvette & Typhoon were equipped with the last production 700R4's, also the last design change of the 700R4 with an added checkball to the valve body.

In 1992 electronic controls were added and it became the 4L60-E. The 4L60E went into service in trucks, vans, and SUVs in 1993 (for the record, some HD trucks had the 4L60) and in all RWD passenger cars (Corvette, F and B/D bodies) in 1994.

In 2001 an updated version, the 4L65-E, was introduced. Five-pinion planetaries, along with a strength-improved output shaft, were improved to withstand the 300+ ft·lb (over 400 N·m) of torque of the 6.0 Vortec engine.

[edit] 700R4 / 4L60 / 4L60E / 4L65E Technical Description

The 700R4 can be identified by the oilpan having a rectangular shape being longer front-to-rear than side-to-side and held to the transmission by 16 bolts, 3 bolts front, 3 bolts rear, 5 bolts left side, and 5 bolts right side.

The tailshaft housing is held onto the main case by 4 bolts (the bolt spacing is similar to the THM350), and uses a square-cut o-ring seal, and not a gasket. The typical width of this transmission where it bolts to the engine is 20 inches (510 mm) overall. From the engine/trans mating surface to the crossmember mount bolt is 22-1/2 inches (570 mm), and engine/trans surface to output shaft housing mating surface is 23-3/8 inches (594 mm) overall, with the tailshaft housing typically measuring 7-5/8 inches (194 mm).

Transmission fluid cooler lines on the 700R4 the bottom fitting on the right side of the transmission is the "out" line to the cooler and the top fitting is for the return line from the cooler. These fittings are 1/4-inch pipe thread, and CAN include an adapter from the factory for threaded steel lines in a SAE size. 4L60Es manufactured after 1995 use the modern-day snap-in connections as opposed to threaded SAE fittings.

The original version of the transmission had a 27 spline input shaft which was a common failure point. In 1984, 700R4s designed for use behind Chevrolet small block V8s received a 30 spline input shaft which used a different torque converter than its 2.8 V6 and 2.2 L4 powerplants. Between 1984 - 1987, internal components, from the ring gear to the oil pump housing, were updated, ending with the auxiliary valve body (for 700s manufactured after October 1986).

In 1995 the 4L60E received a PWM-controlled lockup converter.

Around 1996, a bolt-on bellhousing was phased in (along with a six-bolt tailhousing) when the transmission was bolted behind an inline four cylinder or the Vortec engine family.

The gearing for the 700 is:

* First - 3.059
* Second - 1.625
* Third - 1.000
* Fourth - 0.696
* Reverse - 2.294

(commonly rounded off to 3.06, 1.63, 1.00, 0.70, and 2.29).

:headshakeHello,
it is very nice from you to helping me, but i do not have scanner for transmision so now what?!
I did the oil/filter change and when i took the oil pan off then i saw three or four like electro magnetic relays or switch / valve maybe??...do you know how they control the transmision??...what they for??...i got the manual but there is nothing about it?!
Thanks again :-/

:rolleyes:Hello there,
thanks for the wiki info, but this is not helping :-) :-/

Any check engine lights on?
Is the fluid level good when transmission hot in park engine running?
The transmission is computer controlled.
A scanner is the only way to check it out.

If you do not have a good engine/transmission capable scnner find a good repair shop that does and get it checked out.
Post back any codes.

A factory repair manual or a all data online DIY sub will explain the shifting and trouble code repair charts.

Yeah,
the oil and filter is new, oil level good on hot, no check engine light...
I do have auto xray scanner and i had trouble with egr valve 0404 code. I did fix the egr valve and clear codes, nothing since.
I have been told that there is valve that controls the shifts but i don't know where is it and how it looks like.
I guess i have to go to chevy dealer that i hate ;-/

Shifting is controled by solenoids.
Good Dealer or look for a good repair shop to check it out.
Good luck and let us know how it goes.
