Can any problems with the transmission, cause a car to feel like the engine has no power at all? The engine runs perfect, but will not even do a brake stand or spin the tires from a stop, very low power in any gear, but especially from a stop. It shifts normally, lockup is not working at all...

FWIW, I have switched a high mileage under maintained 2004R over Dex 3 to Dex 6 and it's still going fine with somewhere close to about 200k on it. The fluid didn't seem to make any noticeable difference in the shift feel either. My other 2004R with well over 200k was switched from Dex 3 to...

Thanks very much. I will see if I can attempt this check at work the next few days. I'm hoping it's just the lock up valve is stuck.

Just an update, I replaced the converter a week ago, it does perform better because of the 2025 stall (up from 1400 stock) unfortunately the lockup still does not work. I've already replaced the TCC solenoid and had the electrical all checked out and apparently its all working properly. The...

Hope you guys can give me some advice. The lockup quit working in my 2004R in my winter beater a couple months ago. It has about 200k on the trans, pulled from my old Caprice. When I first got it there was a bit of a whine noise in park (when it had less than 120k on it). The noise went away...

The end of the story on this trans, we failed to make it work. On Saturday we pulled the valve body out, to install a shift improver kit and reassemble. We found one of the very large springs broken (can't remember the name of the part now), figured that maybe it was causing the problem...

Guess I didn't clarify, I did not use the converter from the failed transmission. I used one from a 1983 2004R that was still operable, but had not been test driven. Since there was no torque converter noises, and it locked up quickly (too quickly) during the test drive i'm guessing the...

Thanks I will do that. I will also do a good flush through the cooler lines as well before doing the work, so it hopefully doesn't get recontaminated.

Thanks for the replies. The original tranny to the car did not leave any metal in the pan, there was a whole lot of clutch dust from it burning up over the week it was driven with almost no fluid, i guess it's possible some of that was in the cooler lines and stuck the tv valve. My friend...

I completely understand what your saying there, my only problem is that in my case the calibration of the tranny I'm putting in should not be much if any different than the one that was in it original. It came from a fully loaded 86 Buick Regal with a 165hp 305 sbc (factory Canada spec instead...

2 of the local trans shops (both of which seem to be somewhat knowledgeable about 2004Rs, one of which has built some for local GN's running fast times) are telling me I need to figure out the main problem, to get it working the way a stock non performance 2004R should before doing any upgrades...

I hope you guys can help me, I just bought a $400 daily driver 89 Caprice with the 305 TBI and 2004R trans. The previous owner had run the 2004R low on fluid for about a week and cooked it. She didn't know how to properly check the fluid level with it running, so she thought fluid level was...

Okay thanks, ya when I say it coasts it doesn't feel like theres any engine braking, eithers its in neutral or second possibly. I forgot to try pulling it down from 4th to 3rd at speed, either that or I was scared to because I know what it does in 3rd from a stop. I will try it though. From a...

bump, maybe non turbo buick 2004R questions aren't wanted here? If I don't get a reply within the next few days I won't be back to check again. Please help if ya can guys, I don't mean to be a pain in the ass, I'm just broke and trying to help keep a $300 car running through the winter for me...

I drove the car more today. I found it also doesn't like to downshift to 1st at WOT when it should like at speeds of about 35mph or faster, but at WOT if your already in first gear, it winds out to over 55mph and i have to let off the gas for it to shift cause the engine (a 307 Olds) is probably...

Hey, hope you guys can help me with this. I have a 1983 Delta 88 I'm getting ready to drive this winter and the 2004R in it is acting kind of funny. What's happening is if I put it in drive instead of O/D for in town driving, it just stays in first and revs, when you let off the gas it will...

Bump, any opinions on my last question? Thanks.

Well the transmission in the Cutlass has been fine since I posted this but my girlfriends 94 Grand Prix's transmission failed today without warning :-( so now shes going to be driving my winter beater 87 Caprice that also has a 2004R. The Cutlass has had the tcc hooked up so that it doesn't...

Okay will see if I can borrow a pressure gauge. Fluid is just above full hasn't changed level in 12k miles since flushed last. I remember there being an orange gasket on the filter when installed. Hope I'm right. I'm just wondering what could cause lack of pressure at idle but not during...

Hey guys I've got an ongoing long term problem with my 2004R. It's now got over 210k miles on it. Its had an issue since about 100k miles ago after driving it somewhat hard in hot weather, then parking it for a little while, it would not want to engage in reverse. The problem went away almost...
