Btw, the tranny would shift to go for a passing gear, but alas…

you have a bad plug wire. you were only feeling it in tcc lockup, which your trans mission was shifting in and out of. the plug wire is a problem. the tcc is a fact of life the post i read said new PLUGS. did i miss something?

I’m only throwing this out there from personal experience with my 98 Silverado. You symptoms are what I was going through and even the mechanic that drove thought it was the trans. He said take it easy and baby it, becaus it’d only happen when I accelerated. RPM’s went up, and I went nowhere. After about three months of this, it finally started bucking and I barely made it to the mechanic. I couldn’t go over 30 and it got worse as I drove.

No it doesn’t Elliot: They did away with vacum modulators about 86 or 86, Transurgeon can correct me, he’s the resident trans guru. I’ve rebuilt them, but couldn’t tell you what made them go "Bu Bye!’ He can without taking them out of the car! Transmission guys amaze me sometimes, I call to ask a question and how much to rebuild, and they say why do you want to rebuild? Just do this! Refinish King > What’s the grief?

He said the wires are new – and if he routed them ok… If it’s a misfiring thing it still could be the cap & rotor. At 107K mi that’s a fair age for that part – just like the plugs and wires, especially since pulling off the old wires (if stuck) can crack them.

They haven’t been hooked to a vacuum or throttle source since 1994 in the trucks, even earlier with the cars. 1994+ are completely computer controlled. Stick to welding driveshafts and machining heads with a dremmel wee grasshopper. Doc

Response:
What’s the grief? Is the 98 tranny hooked to the vac or not? He said he changed the plugs – and thus coulda broke or melted a vac hose. I know older trannys needed vac for proper shifting. What about 98?

What doc said +… You may want to check the vacuum lines when changing the other parts (unless someone sets me straight on the year vs Vac…). I’ve had vehicles shift funny when they had vacuum problems (and rpms increase randomly) – though I’m not sure if that connection is still there – or if they’re all electronic now. Anyone know if a 98 engine still has a vacuum link to the tranny?

Your transmission was shifting in and out of lockup. Check your fluid level and quality ASAP. If all checks out ok, change the fluid and filter immediately and have the PCM scanned for error codes. Doc – Hide quoted text — Show quoted text –

RE: 1998 GMC Jimmy 4.3 engine 4X4 A/T 107,000 miles Recently ( within 4000 miles)replaced spark plugs, gas filter and had auto trans fluid replaced (did not drop pan but used machine to pump in new and pump out old) Here’s the problem I went on a 300 mile highway drive. After about 150 miles (at 70 mph) the tach went from a steady 2100 rpm to 2500 rpm but I was always going 72 mph. Also the suv was bucking like it was runing out of gas. Then it would smooth out and drop back to 2100 rpm. Then it would do it again and again etc. I was afraid I would not make it to my destination, but I did. The next day I returned home (300 miles) and it ran perfectly. Any ideas what might be wrong? Someone thought spark plug wires might need replacement but I say why would the rpm’s rise but the speed remain the same it it was the wires. Could the screen in the A/T be clogged? What are your ideas. PLEASE
