hoping this is just a vacuum issue, or low fluid...
I plan on doing a fluid and filter change, but wanted to see if someone could list a chronological order to troubleshoot this.. with details of where to look for vacuum leaks, where to find solenoids, etc...
thanks in advance!

Morph, I'm from Jackson if you need to source another tranny let me know. There's a guy with a small salvage yard that had a tranny (not Oscar Delahoya LOL! ) and two parts car 1 white 2001 vdp with dove/white interior and a 1999 carnival red with tan interior.
Seriously good luck with your car.

Hey, sorry to jump onto your thread, Morph. I have a slightly different transmission issue. if the moderators want to move this post to create its own thread, awesome.. if not, it seems there are some transmission savvy guys here so thought I'd see if I can get some help!!
my issue: bought this car a couple of weeks ago. got it running last sunday. after really enjoying the feel of the V8, doing some rapid accelerations, and giving the guys at the shop a drive around the block, thursday I noticed a slight slippage in the transmission... now, I never spun the tires or anything, just gave it a little gas...
I drove it to work yesterday. as long as I just give it gradual pressure, it shifts fine, all the way to 80 mph... but if I give it even the slightest extra pedal, it slips and bumps... hoping this is just a vacuum issue, or low fluid...

I'm no expert but pretty sure this is not as simple as a fluid/filter change.

Don't know what you have but this symptom fits mine to a T. As long as I took it easy, I was able to get it to the shop. Jag has been in the shop a week. Mike has not yet torn into it. He told me that if he were to go the way of the valve body, this would be very expensive. He is hoping that it could be solenoids and we have already ruled out the A drum since this was replaced with the upgraded one in 2012.

Morpheus, were you able to accelerate all the way up to highway speeds? please keep me posted as to what they find! I'm still driving mine, haven't had opportunity to get mine up on stands in a level location to check the fluids... but as long as I drive it gingerly, I'm having no issues.

I feel certain that this is NOT a fluid level problem seeing as this tranny was repaired and fluids replaced 2 years ago. I saw no leaks.
FWIW! I did notice for quite a while after getting new tires, there was a gear sounding noise(not grinding) in the front right area that I attributed to the new tires. So, when driving jag to the shop, I noticed the sound was missing.
The tranny mechanic has already agreed that there is a more serious problem.
I wished after that 1st costly repair, I would have gotten rid of it.

ah. with mine, I can drive with absolutely no issues. it is only if I put the pedal down and try to launch off, that I notice the slip. the first time I noticed it, I did give it a bit of gas a few times, and only once did it give the gear fault. after that, I just gradually accelerate. I watch the tachometer constantly, and it shifts smoothly... that's what leads me to suspect a vacuum leak. the vacuum is what tells it that your request for power needs a lower gear. someone correct me and clarify if that's wrong... maybe a throttle positioning sensor.... anyway, let me know what your mechanic discovers!

I called the shop and looks like they have been jerking me around.
After 2 weeks, he had merely replaced the light switch for gear shift console. He told me he thinks it made it worse. He made the comment that they would have to now pull the tranny again and then later back-tracked that he has not yet seen the internals of it.
I told him I need my car and he said he would get on it.
If he is trying to get around doing something based on the fact this transmission was worked on 2 years ago and maybe there is something that his mechanics did not catch, how am I to know?
He said there could be some rubber parts in there needing to be replaced. I just don't know what to think now.
I just remembered that last time, I paid him a visit after a few days and maybe that made a difference plus I hooked him up with a new A-Drum from Ebay so car was repaired within 2 weeks time.
I want it back and going to immediately put it on CL and any other place I can. I only want the money back I originally paid for it. $4K

And the issue you'll have; since you bought the part yourself, no mechanic will warrant it. If you buy the parts through the mechanic, they will usually give some length of a warranty, though doubt it would be two years... How many miles Did you put on the car since the last a-drum? Did you change the fluids after 30 k?

Hindsight! It most likely needed a new OEM drum and valve body work.
I like the jag and overall, it is still in good shape but I don't care for the headache. I think the only thing it needs now is a thermostat and coolant sensor.
It just didn't work out like I wanted it to. Driving 22 miles a day @ 110 miles a week. That's nothing! A car barely valued at $4000 that I've invested almost $10k in... time to cut my losses!

Got the jag home and ran fine. We were going out. It would not crank. I was seeing a failure message. I gave up. Later came home and manipulated shift around... got it to crank and noticed several codes including gear fault. The tranny may be repaired now but left with electrical problems.
The drum was a new part but not oem. I'm going to work around the problems for now because I need the car. I am not happy!
