It wouldnt be the spark plugs.. It would be doing it all the time if you had a mis-fire. It sounds more like your torque convertor going bad, or your shift solenoid.

Try some tranX. My transmission would drop out from 2nd and 3rd , I put this in and with in 3 days it quit slipping. and shifted normally. It's been over 2 years now without a problem

Sometimes if you got a transmission that don't match the computer that controls it, you get this kind of problem. For example if you got a differenty year model from the original.

My 95 Cummins Dodge had the same problem and adding "Lucas Transmissiion Fix" cured it completely and permanently.

Thier claim is as follows:


Lucas Transmission Fix is a non-solvent formulas that stops slip, hesitation and rough shifting in worn transmissions and completely eliminates most seal leaks. Use in any transmission for preventative maintenance.Use also in light duty manual transmissions to increase shifting ease and transmission life.
Key Benefits

• Contains no solvents
• Lowers operating temperatures and stops foaming
• Can be added to existing fluid without draining any out
• Effective in an extremely high percentage of cases

possible speed sensor at rear of transmission,does engine rpm sound higher then narmal,and is your trans shifting as it should,if these problems are also present replace the speedometer sensor at rear of trans,$50 to 60 bucks

sounds like a sticking shift solenoid have trans. serviced and check i would recomend factory fluids

check throttel valve cable it shoul be with adjusted to 1/32 in eather direction of the throttel stud

I had the same problem with my 96 Ram 1500. I thought I was going to have to pull it out and get it rebuilt or just replace it. That was at 134,000Km it's now got 210,000 and shifting like a dream. What I did to solve the problem was this, as follows:
1. No lucas transmission Fix makes things worse.
2. Get your self a new transmission filter and gasket
3. Grab Gunk transmission medic 12oz
4. Grab 7 Liters of Valvoline ATF+4 transmission fluid (Made for chrysler transmissions)
5. Drop the trans pan and drain all the oil, clean pan and magnet
6. start truck for 5 seconds and the pump will pour out another 1 liter
7. re-install filter, gasket and pan, then add your Valvoline ATF+4
8. Add, the valvoline, transmission medic and make sure you have the right level of fluid

That solved my transmission problems, instantly it was shifting better, I no longer had to let off the gas to make it shift. Now if you have large pieces of metal on the magnet, and it's totally covered in filings, you might want to consider rebuilding the trans. My magnet had usual clutch.         

Anyhow good luck, let me know if it did the trick for you.
