I have a post in the towing section that asks what rpm corresponds to what speed when towing.<br><br>I have a 1st gen, and towing with trailer, I would like to keep the engine running above 2000 rpm while towing in overdrive, but I have no tach fitted. Could someone with the four speed auto transmission and 3.54 rear end tell me what speed 2000 rpm corresponds to in both O/D and in third?<br><br>Thanking you in advance.<br><br>John

i think on my uncle's 92 auto, 70 is about 1800rpm in OD with the stock 235/80 tires, and a 3.54 gear

<br>i think on my uncle's 92 auto, 70 is about 1800rpm in OD with the stock 235/80 tires, and a 3.54 gear<br><br>Thanks Furious70. Actually I got a lot of responses in the towing section, the reason I posted here was I didn't think that there were that many 1st gen knowlegeable towing people in there. They all seemed to have new stuff. I guess they all must have upgraded before I got here. ;D<br><br>John

3rd gear is 1:1 on these tranny's.<br>You want to keep RPM's at or above 2000 RPM because of the TC. Otherwise you'll start getting too much heat in the tranny. Not good...<br><br>bob.

TC=Torque Converter.<br><br>Lots of acronyms here, that is but one of them.<br><br><br>phox

Rats !! sorry about that...<br>TC = as mentioned.<br>VB = Valve body<br>TPS = (Pain in the A _ _ ) Throttle Position Sensor.<br><br>Bob.
