At around 210,000 miles, I had my auto transmission replaced with one I got at a junk yard.

It worked fine for a bout 1.5 years. Now it is hesitating going from 1st to second - like it was a manual transmission and you're releasing the clutch very slowly.

I have read it might need more fluid.

I have the Bentley manual and read there are two types of trannys for that car. One where you can add oil and one that never needs oil replaced.

I see what looks like a dipstuick tube in the engine compartment going toward the tranny but I can't get the top off of it.

I don't know if I had a permanent fluid tranny and the tranny was replaced with one that where you can add fluid or vice cersa.

Either way, I need to find out if the fluid is low so I can try this tactic first before I take it to a shop.

Does anyone know how to find out if the fluid is low?

If it has an arrow on it, push in the direction of the arrow and pull up at the same time.
Good Luck.

Many thanks guys. I will try that technique today to get the dipstick out.
Yes, it does have an arrow. There are no instructions in the Bentley
manual.

Also, the symptom I am experiencing are:
--Starts out in first gear, then QUICKLY (around 7 MPH) shifts to 2nd gear.
--That shift is the only one where it feels like if it were a manual tranny
and you were letting the clutch out very clowly - slow to engage the next
gear.
--All the other gears shift fine.
I can start off in DRIVE 1 - forcing it to stay in first gear, then shift to
DRIVE 2 and the shift is slow. DRIVE 2 -> DRIVE 3 is fine as are the
others.

'90"s have a dipstick and you can chnge the fluid and filter, which I would encourage you to do. That may do the trick.

If not, the seal on thr main shaft could be on its way out. Winfred has a great write up on this in the drive train section of this forum. I did this repair to mine when it started slipping and it worked perfectly for about 35K. Then, it wouldn't shift out of 1st until it warmed up.

I changed the fluid and added a bottle of Lube Guard (red) as per Kirk the guru's suggestion. Now it works fine.

IMO, sounds like the seals are going.
