Is my transmission dieing? "Shutter" maybe?

Hello...this will be my first post and hopefully I can provide the necessary information to help diagnose what is wrong with my transmission.

I've been doing a lot of reading around, and in particular, I've noticed a few people have shared my experience. I drive a 1995 Mercury Cougar 4.6L V8 Auto with 210k miles. I forget the transmission model number...but here is my problem.

In Park...everything is all good. Engine is sitting around 700 ~ 750rpm. I shift into Drive and there is a sudden jerk, engine rpm drops to roughly 490 ~ 510rpm. BUT...during the change from P to takes a few seconds for it to actually 'get into gear'. I deliver pizza so I go from R to D a lot...and when I can't get there quick enough it causes problems with traffic. Say I pull into a drive way to turn around, car comes to a stop. I go from D to R and I can actually count maybe 1 or 2 seconds out loud before it gets me in gear to reverse. From what I transmission is dieing? Either that could use a new filter and some new fluid...not sure when it was last drained either....she is old. Thanks for everyone's replys!

I would drain the fluid from the torque converter and the pan and refill with Mercon V and add a new filter. If you don't know when the last time it was changed, it's probably wayyyy overdue.

Let me ask you this, have you checked to make sure its full on fluid? What color/smell is it? Does it look brown like it's burnt, or is it still nice and red?


These are highly engineered precision vehicles, the first step in diagnosing the problem is to strike the suspected offending part sharply and repeatedly with a blunt object, then re-test.

i would pull the hardlines off it, and flush gunk out of the hardlines with some spray from

Then drain the transmission, and refill with mercon V.

Make sure you put a new pan filter on, and clean up the pan with brake parts cleaner.

There is a good tech article on doing this.

Should cost around 50 bucks in parts for everything.

If you’re not comfortable doing this work yourself find a reputable shop to do a pan drop and completely flush the transmission. Most shops have a machine for doing this. A transmission fluid flush and fill should run around $130.00. If you plan on keeping the car and have the funds I’d also recommend getting an auxiliary transmission cooler installed as these transmissions run hot.

Mods? Yea, I got mods ...

I would suspect an epc or possibly pump problem. Darrin is in indianapolis. It's not really that close but I am sure he can fix it.
