I missed the first part of his post. Do you know what pulley they’re talking about? I’d definitely like to have an accurate tach.

Where would you put that if you were trying to use it to determine rpm’s? I was thinking it would, just wasn’t sure where you’d put it to get an accurate reading. I do have the 400a.

950rpms. Does that work on diesels though? Normally diesels are harder, normal tachs don’t work on them.

What do you consider a lower top end?

I could throw a wrench at it and fix it better than Aamco. 😄

I’m not doubting the gearing you mentioned, I’m just wondering if something is wrong with the transmission. Could something be wrong with it throwing the rpm’s higher? I have a m998, I know this has a turbo but I’m well aquatinted with the top speed and the noise this engine produces, I’m almost...

In 1st gear, I’m hitting 3k at 15mph. I don’t think it’s wrong. I could be mistaken but I’ve had to drive some diesel work trucks and like I said, I’m pretty accurate. How would I verify?

It’s definitely not in 2nd, I can go 55 and it’s 2700 or 2800 rpm’s. I also can run up to like 45 in 3rd and then shift it to 4th and it definitely changes. how would I confirm? Because if I just assume it’s wrong, I’ll blow the engine. I don’t think it’s off, it’s screaming at me and I only...

It was still shifting. It would only go up to 3rd gear, no Od.

Any idea if the tps would cause something like this? Last night I accidentally left it unplugged and I could only go 55mph, once I connected it, I was able to go higher 63-65. Wasn’t sure if adjusting the position would affect rpm’s in a significant way.

And there are no codes on the transmission.

Yes, it does it on the 37’s and 40’s. I gained 2-3mph with the 40’s.

I should have mentioned, I did follow with gps and it surprisingly the speedometer is correct or almost. I have 40’s and I probably got closer to 65 at 3300rpms. I’m getting very frustrated, I just got this because I was tired of the limited range of the m998 and I’m not much better off until I...

Did any of the m1152’s come with really low gearing? I’m having trouble with my new 52, I’m at 3300rpms at 63-65 when multiple other people say theirs is 2700-2900 at 70-75. I believe I feel lockup, either way, it wouldn’t drop that much. I have shifted from 3rd to 4th to make sure it actually...

Excuse my ignorance but what would unplugging the converter half do or test? Sorry, just trying to learn.

I feel it shift 3 times so I’d assume it’s going through all 4 gears. I don’t really know about the lockup, I’ve been driving a cvt vehicle for so long or a manual before that.

I think 3.08 but other 1152’s can do 70 on lower rpm’s.

Any ideas on where I’d need to start? Someone said brake switch but I’m confused how that would help top speeds, I assumed when you pressed the brake to decelerate, it would unlock but it’s not as if you press your brakes while accelerating so I would think default position(not activated)...

I guess it’s possible, I honestly don’t know much about transmissions and fixing them. I got lucky with figuring out the wiring but I figured it would throw some code if something like that was broken.

It feels like it. I go into 4th and then it slightly kicks down and drops 200 rpm’s. But I do feel it shift 3 times.
