Update - FLASH ALERT.
I pulled out trani dipstick tube to loosen off the last of the rear manifold bolts.
You can get at all the bolts from the top side. From underneath it'* difficult to get enough force on the rachet.
Anyways....I compared the original dipstick tube and dipstick to the new offset dipstick & tube from the earlier model GTP as recommended by the group....and there are major differences that are very worthy of note
The tube itself being offset turns out to be 1/2" longer than the original and the dipstick is longer to make up for it, as you might expect. The original dipstick protrudes about 5/32" more out of the original tube so you wouldn't think that this will make much difference.
WELL, the scales of both sticks are off by about 5/8".
That means that if you go by the new scale, you would be adding about one liter or 2 pints more fluid than you should and that could spell disaster
If you try to put the original stick in the new tube, it'* too short by 11/16".
The scale of the new stick is twice that of the old one so 1 pint on the new stick is actually 2 pints.
So I,m going to scribe a new scale to match my old one.
Let me know if you find the same opportunity.
