Have a 1995 Dodge 1500 with a V-8 engine with auto tranny.

Problem: Overdrive does not seem to engage normally.

Overdrive will shift if higher than normal rpm is achieved, or
if I let off the gas the compression will engage the overdrive?

I have heard of ford cars having similier problem which is due
to fuel filter/tune-up related problem.

However, cannot find a fuel filter for the 1995 dodge?

any suggestions.

have checked fluid levels,etc without finding any problems

Has the truck been to the dealer lately? The dealer will, unbeknownst to you, reflash the PCM to raise the OD engagement point to approx 60mph.

You should also check the TV cable that runs from the TB to the trans.

It will not shift into OD until the coolant temp reaches 60F nor will the TC lockup til coolant temp reaches 130F.

Has it been colder lately?

HAVE SOLVED OVERDRIVE PROBLEM

I beleive that I have found my problem with the Overdrive
not kicking in normally..

First checked the TV cable, did a minor adjustment which helped
a little bit, but not completly,

checked my records on the vehicle, last time the transmission
was serviced by the dealer in late summer in reads installed
DEXROn III trans. fluid.

According to my owners manuel it should be Dexron II, don't know
if there is that much of a difference or not, but after draining/
filling with new fluid it now works fine!!!

It was worse in the cold mornings, but temps here have not
gotten below 20degrees and truck sits in shop at night.

Anyway it works fine now, thanks for the input, oh yes it is
raining and 50 degrees here today.. 3w

Read it again. Preferred fluid is 7176 Mopar. Dexron is not really recommended but can be used if 7176 is not available. But the only real effect the Dexron would have is make torque converter shutter more noticeable.

In the 7 years sine your truck was built 7176 has become just as common on the shelves as Dexron/Mercron/Type F.

Glad it worked out for you.
