Hi ,is there a recall for transmission oil cooler.

The governor pressure sensor is the most likley cause however an inspection of fluid or debris in trans pan would be a good idea to make sure there's nothing excessive in it. Attached is a list of possible causes however the senor would be the most common.

POSSIBLE CAUSES

• Powertrain control module
• 5 volt supply circuit open
• Check transmission fluid level and condition
• GOV press sensor signal circuit shorted to voltage
• GOV press sensor signal circuit shorted to sensor ground
• GOV press sensor signal circuit shorted to ground
• GOV pressure sensor signal circuit open
• Sensor ground circuit open
• GOV press sensor signal circuit shorted to voltage inside transmission
• 5 volt supply circuit open inside transmission
• Intermittent governor pressure solenoid
• Internal transmission problem
• Oil burnt or oil pan has excessive debris
• Other transmission DTC'S
• GOV press sensor signal circuit shorted to sensor ground inside transmission
• Valve body
• GOV press sensor signal circuit shorted to ground inside transmission
• GOV press sensor signal circuit open inside transmission

no good

Unfortunatly this IS the FIRST Gear that FAILS when Trans is about to Completly FAIL. Answer YES

SOURCE: What causes the oil pressure gauge to fluctuate on

If the oil pressure is good and there is no engine noises then the oil pressure sending unit is the problem.Just replace it and you should be good.Hope this helps.Good luck.

First things first do you have a repair manual? If you don't have one get one, Changing the unit is realitively simple, you just disconnect the battery, disconnect the oil pressure sending unit's electrical connector, remove the sending unit, now most sending units are small and look like a short chubby spark plug with an electrical blade connector on the end of it. simply use a wrench to loosin and remove and install by screwing in and tightening and reconnecting the electrical connecter then the battery and your as good as new!
