Default 1996 Tranny OD stutter

While driving at lower freeway speeds during commuting (ie 45-55mph) and
then accelerating I notice a shutter. This only happens when the car is in
OD at these speeds and thus a low RPM. If I am driving at 65-70 and need to
accelerate, I hardly notice it. Otherwise all seems great in arounf town
driving.. Anything to worry about (always is isn't it?) or some possible
causes? I just hit 100,000 miles so I want to go another 100,000 if I can.

Thanks IA

Do you mean the engine hesitates? A hiway speeds and thus high engine revs,
a hesitation is not that common as any small abnormalities such as airleaks
or injector performance are small compared to the air/fuel the engine is
calling for. .

Can only guess that either the ignition-advance is not responding quick
enough due a sensor problem (manifold vac or TPS) or the spark is low and
causes misfires when the combustion chamber pressure rises with a throttle
increase,...unfortunately if the 'engine' icon is not alight (indicating a
fault in one of the systems), then an experienced engine tuner maybe needed.

Prior to that Id do the folowing:


- check obvious things like air-filter
- loose or missing sensor connections
- make sure air-intake plumbing is secure (clips) and there are no splits in
the hosing
- check intake plenum and intake manifold nuts are tight (causing possible
airleaks)
- ascertain if the plugs are original
- consider replacing the ignition leads if original
-make sure the oil-cap and dipstick are secured
- check PCV system hoses are OK and consider replacing the PCV valve. These
do not last forever.

It could be dirty fuel injectors --- add bottle of Chevron Techron FI
cleaner to gas. I'd drin the trans and replace with new fluid if you
haven't done before.; It doesn't replace all but you can do again in
another few monthsl.

You mean trans slipping not motor, change trans oil and filter .
