Question about 1998 Chevrolet C1500

1 Answer

I just installed a used 4l60e in my '97 Tahoe. On test drive, it shifts from 1 to 2, then about 1/2 way to 3, it downshifts back to 1. Any ideas about the problem?

How many miles on the tranny your put in? those don't last any more then about 120-140. the sunshell breaks, you should replace it with "the beast"

all shifting is in the valve body, you don't need to remove the tranny again. If your going to open her up and start wrenching, get a video/book on the 4L60E, you will start with check electrical components

Albert, Have truck scanned for trouble codes. To test a transmission solenoid, use hand held ohm meter. Instructions in second link below, the attached links are informative on the different procedures used to test solenoids.

I have a 95 silverado c1500 with 4l60e trans and it wont go into overdrive


overdrive is the fourth gear.D1,D2,D3,D4 now drive truck at 80 kmh
cruise at steady speed no fuel pedal movement, downshift from D4 to D3 you should feel RPM raise .. after push brake pedal a little you should see RPM raise 300 to 400 rpm.
shift pattern is 1st gear ,second gear,3rd gear and lock up(torque converter clutch). 4th gear with lock up
hope it helps

My 99 jimmy with a 4L60E, on a downshift (kickdown) at highway speed or any speed really when downshift by pressing down the accelarator or downshifting by hand the tansmission feels like it's in neutral,...


First off there may be nothing wrong. At highway speed, the trans will shift down to 1st, but you won't feel it. If should feel like neutral. Does it shift normally when your "wide open throttle" from standstill? If it shifts properly in this situation, then your fine, don't worry. How about wide open throttle at say 25mph? how about 35 and 45? anything over that and its gonna feel like neutral. IF your convinced that your passing gear is not working right, it could mean that its out of adjustment, and needs a little more push, more throw, or kinda like adjusting the rod out a little bit further. Adjust your "passing gear linkage" or kickdown as you imply. Second guess would be low on transmisison fluid, filter, and last, the transmissoin control selonoid. Again I suggest its doing just fine, if it shifts down at any speed.

97 chevy tahoe wont shift into 3rd or 4rth.


The transmission is probably a 4L60E or 4L65E the third and forth clutches and steel are probably burnt out or the clutch piston has blown it's seals very common on those transmissions.

1996 Tahoe error code P0700 detected at PepBoys


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.

96 s10 4cyl automatic shifts great through 1-3 but seems to bottom out and even downshift instead of going into overdrive, drives fine when in drive only.


I believe you have a 4l60e transmission.Do you have a chck engine light? The unit may have a 3-2 downshift solenoid going bad or a possible band ''servo'' leaking. The band applies in 2nd and 4th.You may also have a shift solenoid starting to malfnction......Best
