#93 of 319 1996 Chevy S10 Shifter Problem
Nov 26, 2007 (5:51 pm)
1996 Chevy S10 Regular Cab with 4.3 L V6 and 5 speed manual transmission. The truck has 78,000 miles and I just had the clutch, flywheel, clutch bearings and slave cylinder replaced. My question has to do with the manual gear shifter. Before it used to stay centered on 3rd and 4th gear when in neutral but after the clutch repair it just slops back and forth. I canít seem to find a detailed schematic to see if a return spring was left off or what the problem might be. The mechanic said this was ďnormalĒ and didnít see a problem. Any ideas on what could be causing this? Thanks for the assistance.

I just a 96 S10 2.2 liter 4l60E Overdrive Automatic. It had 82,000 miles in good condition. the shift seleonoids are bad only had 2nd and 3rd gear. I took the truck to the transmission shop, I had the transmission flushed, new fluid filter and seleonoids, the problem was fixed. Axp 1,000 miles later while I was driving in town it instantly downshifted into 1st like someone was putting the brakes, but only for 5-10 seconds. Then it seemed fine. The next morning I was driving to work, about 5 miles, and about the time I got to work it did it again. I seem to have all my gears, but it is doing it all the time now. I can not get up to speed, up to 20 mph. I was told that the automatic transmission behind the 4 cyclinders are prone to failure is there any truth to that, if it is bad and have to have it replaced, I don't want to have to worry about it failing early again.

Take it to a good independent transmission shop and have them scan it with a transmission capable scanner. That will give you a better idea of what is going on.
From what I have read the 4 fails about the same as the 6cyl.
My 4 auto has only 53K, so I don't know how long mine will last.

I dont know! But my dad just gave me a 1998 S10 LS three weeks ago and the reverse gear slipped three or four times and went out yesterday, but still works fine otherwise. Any ideas let me know please? My friend said it could be the linkage and I could fix it, I have no idea about this.

Ok, my problem with my transmission is this.. i have a 2000 gmc sonoma, 2.2. 2x4.. automatic... i will be cruising down the road in top gear(4th) .. and it will downshift into 3rd gear.. it will not shift back up. even if you floor it.. the only way i can get it to go back into 4th.. is to pull over and turn the ing, completely off, and turn it back on.. that will fix it momentarily. only for it to happen again about 15 mins later.. ive noticed it only happens on long trips. its ver irritatiing. after about an hour of freeway driving.. you cant just pull over and pull back out, u have to acutally turn the car off for it to be fixed.. also.. the service engine soon light is on, and its gives a code for the transmission.. does anyone have a clue as to whats causing this.. anyhelp will be greatly appreciated..

I bet it will be PO 1870 slipping. The latest information I got on this malfunction are worn pump bushings. Earlier the fix was repaired or remanufactured valve body.
The thing is to replace the worn pump bushings the transmission has to come out, the valve body can be done in place.
You need to go to a good independent transmission shop, stay away from the chain shops, they just want to replace the complete unit.

Canít help on pricing, you could ask for an estimate from a good independent transmission shop. A repair can be done, but if high mileage they will recommend a rebuild.

Help! Iím at my wits end. Did you ever see a tranny that throws all its codes at one time? Itís an automatic on a 97 S10, 4.3 with 90k on it. In our case it is intermittent. Sometimes it will allow you to clear all the codes and it runs beautiful. Then out of the blue is goes snafu and has all the codes you can mention on a tranny. I'm confident itís an electrical thing. I pulled the pan, replaced the two solenoids to the tcc, and replaced the filter, fluid. All of which looked A OK. The bottom of the pan was clean; the fluid was bright red from where I changed it last year. When I put it back together and backed it out of the shop the light came on and still had all the codes it had before. Basically I wasted half a day not to mention the parts cost. What ever happened to good ole power-glides? If you have any suggestions on what magic does the trick please let us know? John

Remove the large 20 pin plug into the transmission and see if it has transmission fluid in it. This has been an issue at times.
