Question about 1996 Chevrolet Tahoe

1 Answer

1996 Tahoe error code P0700 detected at PepBoys

Installed a performance level two 4L60E in my 4x4 Tahoe. Also had it setup for towing.
The performance is great, firm shifts, but not harsh, upshifts and down shifts as needed.
Problem is I keep getting error code P0700. After some reading I became aware of grounding issues with some early 1996 Tahoe VCM's. I checked serial number of VCM and it has the upgrade ground wire from factory. The transmission builder also suggested an additional ground wire to transmission case and chassis in case paint on bell housing ruins the ground path to engine.
I also have two other codes since replacing transmission: P0140 O2 sensor and P1192 dealer specific code?
Not to confuse the issue but these maybe related due to disabling features of computer system.
Does anyone have any ideas on what is causing P0700?

    P700 IS A COMMUNICATIONS ERROR WITH THE PCM, IT IS NOT A FAULT CODE PER SAY.

P0140 Oxygen Sensor Circuit No Activity Detected (Bank 1 Sensor 2) P1192 Post-catalyst Fuel Trim System Bank 1

Replace the O2 sensor after the catalytic Converter and check to make sure the wire harness and clips are not damaged. Also check the O2 sensor fuse in the fuse panel to make sure there not blown. 
As for the p0700 code is a generic code and the ECM needs to re-calibrated for the performance upgrade in your transmission. It's common to happen when there are changes like the transmission fluid pressure has been altered which would give it a better and firmer shift, but the transmission reads the higher line pressure as a problem. If you take it to a good transmission shop with a tech2 scanner, the tech2 can change the transmission ECM parameters and that way it will recognize the higher transmission line as a norm. 
Have done a few upgrades on the 4L60E with a common swap of the servo's with a corvette servo's ($45.00) to firm up the shift and raise the transmission line pressure to keep the slipping to a minimal and also bring down the shift points at WOT on the 1st-2nd shift to get going a bit faster (used Tech2 scanner). 
Good luck and keep me posted, be glad to help.

Will a 1990 chevy 1500 truck 4x4 transmission fit in a 1997 4x4 chevy tahoe


yes it will as long as it is the same model transmission. As long as you get a transmission out of a standard cab truck you should be ok. ( for a good idea Most 88-98 gm trucks, full size blazers,jimmys,tahoes, and yukons will interchange) same chassis just different bodys and emblems

Is it true that in a 1996 chevy tahoe 4x4 u can't convert the transmission with another year model like the rest of the1997s. The dealer told me with the 96 4x4 has to be replace with another 96. but 97...


The key distinction of the Later 4L60-E (1997-2006) from the Early 4L60-E (1992-1997) or 4L60 (1990-1992) or 700R4 (1982-1989) is the six-bolt "hex" rear output or tail housing / adapter pattern. The previous versions featured a four-bolt square bolt pattern at the adapter or tail housing. This is where that made the small change and the 96/97 year was a change over year so you may have the newer housing or the older housing, but if your replacing the transfer case with the transmission your good to go, the electronics are the same. Just the body housing is different. Good luck and hope this helps. And why wold you want to convert the transmission, there are lots of easy simple up grades with out dropping the transmission or valve body.

P1153 insufficient switching p0700 1996 tahoe


P0700 - Transmission Control System Malfunction, clear the code and see if it comes back, all this code is, is the TCM (trans control module)
telling the check engine light to come on for a possible trans fault, many times it is a false code and means nothing is wrong unless it has another trans code stored with it like a shift solenoid for instance.

P1153 - Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 2 Sensor 1, You would be pretty safe to assume the O2 sensor for cylinder bank 2 ahead of Cat converter is defective.Bank 2 is the side opposite the bank that #1 cylinder is located in.
