I'm not familiar with the 87-89 factory oil gauge as I have a 93 that came with a dummy light only. I will say it probably is more responsive than what you are describing. I can detect the change in pressure when it changes gears. Or to say it another way, I can tell the pressure is higher with higher rpm's and vice versa.
I added a electric oil pressure gauge recently. The thread in the block for the sending unit is 1/8" BSP for anyone wondering. So when you get your sending unit and it comes with 1/8" NPT you'll need to get an adapter to go from 1/8" NPT-27 to 1/8" BSP-28. I finally found one after much searching at O'reilly - Equus part number 9848.
I ditched the dummy light, who needs it when you have a real gauge
Can anyone verify what size and thread type the block is. I've got a sending unit that is 1/8 NPT and it doesn't fit, I need to get an adapter but I don't know what size and thread I'm looking for . Any help is much appreciated
quick question, will a D44 from a 98 JGC be good for a front axle? There is a local CL post for one for $50, good deal? I only know enough about SAS for my mental flag to say "$50 is a good deal". Enlighten me experts.......
Maybe Mike will chime in here, definitley check your tans fluid and hope it doesn't look like stawberry milk shake. From what I have read the original rad was manufactured by calsonic and there is belief by some that was the reason for the leaky rads/failed trannys. So stay away from calsonic is my best advise
