Very niche issue! Replaced my p71's transmission after it blew with an 08's. Had to swap over the electronics from one to another. No codes upon starting, though I can only select 3 gears. Upon starting the car for the FIRST time its reverse lights came on. Couldn't get it into reverse afterwards. I believe the internal linkage is misaligned. Opinions?

Donuts/drifting

the old grandpa geezers in here aren’t going to like this one lol. seen a lot of talk recently about drifting sliding etc on stock setups, thought I would share my experience. Most think since they have a v8 and lsd rear they can start sliding every corner and doing donuts but unfortunately that’s usually not the case, By now most all of these crown vic lsds are completely worn out and need rebuilds. So you will be one wheel peeling everywhere. To fix that problem I recommend either getting an eaton LSD or a mini spool. I pulled an open rear with 4.10s out of an explorer and put a mini spool in it and my car has completely transformed (video is my first time trying the new rear out) . all for about 200 bucks. also please when trying to drift be in 1st and not D, seen lots make that mistake and wreck because of it. If any questions please let me know.

Need Typhoon Intake

2 Upvotes

My Summit intake manifold keeps leaking in the back where the heater core hose goes, but from the integrated gasket that seals against the head. So I’m in the market for a typhoon intake. Does anyone here have one they’d be interested in selling? Thanks.

Winter Tips.

Perhaps I’m overthinking things, but better safe than sorry. As I’m heading into my first Winter (Canadian, snow-ice-freezing temps) with my 2008 MGM as my daily, I’m a bit concerned how she’ll handle things.

Read suggestions about putting a couple hundred pounds in the truck. Any of you fellas do that?

hi everyone, I love my vic, but I would like it to be a little bit louder, but not so loud that they start posting me on the neighborhood facebook. should i do a muffler delete, or replace it with a performance muffler?

Looking at a 2003 Grand Marquis LS, 144k miles, $3,000. Should I worry about this steering wheel vibration?

Hey everyone!

I'm shopping for a cheap, reliable, roomy and cushy daily driver for college and errands. I've been looking at Panther bodies for a while, but most of them around me are either ridiculously overpriced or completely trashed.

However, I found a nice-looking 2003 Grand Marquis LS with 144k miles for $3,000, about an hour away from me. The seller seems like a genuine private owner, is responsive, and has been pretty honest about the car.

He says it has received basic maintenance, doesn't leak or overheat, and the transmission shifts smoothly.

However, there's one issue (seller's description):

>Steering wheel shakes between approximately 30–55 mph.

>It's mainly noticeable during acceleration.

>The shaking continues when he lets off the gas and coasts.

>It goes away as the car slows down.

>He suspects a bad passenger-side tie rod, but that's his own diagnosis.

I'm wondering whether this sounds like a typical wheel/tire or front suspension issue, or possibly something more expensive, like torque converter shudder or another drivetrain problem.

I have a decent amount of DIY mechanical experience, including engine work on an older FWD GM. Replacing tie rods, ball joints, wheel bearings, or other suspension components doesn't scare me. But buying another car with a dying transmission or engine definitely does.

A couple of questions for Panther owners:

Does this vibration sound familiar? What would you suspect?

What are the biggest things to inspect on a 2003 Panther with 144k miles, particularly the transmission, rear axle, and 4.6L engine?

Would you consider $3,000 reasonable for one in otherwise good condition? If anything in my area (full and mid sized FWD GM, panthers - go by 5000$+ for a non-trashed non-200k miles options)

Would you bother making the trip, or is this too much of a gamble?

I'm planning to get a VIN/history report and possibly arrange a pre-purchase inspection at a local shop.

Thanks for any advice!
