92 bonny with 253k (not bad)...car will start normally and no hesitation and feels smooth, after putting into gear will accelerate to about 30/40km, but rpms will increase as i push the accelerator, cannot feel gears changing. will pull over and turn off car, wait 1 minute and start, this seems to fix problem, once it is going it is fine/good acceleration. This happens a few times dailyt. I'm on the road all day and start/stop car about 15//20 times daily ((normal) for me). This just started a couple weeks ago after the Crank sensor has been replaced, new delco plugs, ngk wires and one of the ignition coil packs. whenever we check the other packs there is spark. ignition module was cleaned up and remounted with good grounding. fuel injectors work well. there are NO codes. as the day goes on the idle is a little bit rougher. fuel pump has been checked. Intermittent problems are difficult, but any help or past experience with similar problems would be appreciated
if a and b solenoid in tranny is fault will code come up ?
with no codes, could crank sensor or wiring to sensor still be faulty?
ignition module, intermittent, if faulty?
yes, original tranny still works well when working if its not the tranny?

try some lucas trans fix it may clean that up

Great description at the beginning.. tough to follow at the ending.

Are you saying you are having some intermittant rough idle issues? That could affect the trans shifting.. Although at that mileage..it simply could be time to rebuild.

Just FYI i think its kilometers, if that matter for mileage......

Check your trans fluid. What does it look and smell like?
