Clint,
I can see the need for trans fluid to come up to temp
but another $450/$500 radiator is not in my budget right now. I
figure if I give the trans a chance to warm up a bit on those cool (LOL)
60º days, it'll be alright. I disbelieved the "...no fuel mileage
improvement..." part as well. A 30% reduction in engine
speed has to improve mileage, especially when we're talking 3 to 4 hrs of
steady highway speeds. It may even lose a bit of mileage in town due
to the converter slippage in Drive, but I can live with that. BTW,
it was Jeff I talked to. He wanted no part of a installation and
"fabrication of the rear mount, cutting the driveshaft, etc..." He
did mention Ken Walker (?) but I may still take it to Phoenix Trans in
Weatherford since they will install everything. They're also a Lokar
dealer so I can get the throttle-body attachement and Lokar cable to match
the throttle.

Re: [Chevelle-list] Trans cooler
Dale, I have a 200-4R (but not in a Chevelle) and after talking it over with some engineer friends (they have thermodynamics backgrounds) we came to the same conclusion about the cooler line routing. Trans -> aux -> rad -> trans. I can't remember exactly which B&M cooler I have but it might be 1 step down from the 24K - maybe the 19K version? IIRC there are 2 coolers that're 3/4" thick and I bought the larger one. As far as MPG goes I'm definitely seeing an increase with the overdrive, especially since I opted for a lockup version. However, I cammed and timed the engine with the OD in mind so the powerband is nice and low. I imagine it's certainly possible for an engine built for efficiency at higher RPM to run less than optimally at lower RPM. And while it might not make a difference for you, I like the idea of the auxiliary cooler taking a little bit of the load off the cooling system since the ATF's cooler when it reaches the radiator.

Re: [Chevelle-list] Trans cooler
Title: Trans cooler Actually Dale, 200 deg. is not high. You really would like to keep it around 185 - 190 deg. You want to get the temp. up as soon as possible. Cold fluid is not a good lubricant. The guy who told you about the cooler is correct. BUT, you want the trans fluid to go through the aux. cooler first then the radiator to maintain the correct temp. Believe it or not but your heater core water is the first warm water your trans cooler (rad) will see because it's piped before the thermostat. (in most cases. I better say that). You don't have an automatic trans radiator so the guy may be right about not warming up fast enough. As I said earlier, you want to get the temp. up as soon as you can. If it were me, and I was going to invest in a 200R4 I would also get the automatic radiator. You will improve your mileage with the 4 speed. If you have a 3.08 or less rear gear you should use a converter with a stall around 1900 - 2000 or the engine may work too hard at low speed. Ideal would be a 3.42 rear for best performance. Also be sure you use the lock up converter and not the duel pitch. Hope this helps you out. RichACES # 05066 - Original Message - From: Dale McIntosh To: [EMAIL PROTECTED] Sent: Monday, July 28, 2003 11:50 PM Subject: [Chevelle-list] Trans cooler I spoke with a guy tonight about building a 200-4R and he said something that kind of surprised me. Even if you run an auxiliary trans cooler, you should still run through the radiator connections as this helps to warm up the trans fluid to help the seals. If you start anew on a cool day (60º was his example), it takes the trans too long to warm up via just the auxiliary cooler. Anyone hear of something like this? What should minimum trans temp be? I think 200º is on the high end, but what's low and what's optimum? I'm getting antsy to swap my M20 4-speed setup for a 200-4R but don't have a trans cooler in the radiator. I bought a B&M 24,000 GVW Super Cooler unit and now I'm told it won't warm up the trans fast enough? He also said that the O/D won't improve mileage to any degree. Somehow I think reducing RPM's from 3000 or so at 75/80 to 2000 or so has to improve mileage - am I wrong here? Currently I'm running 2100 at 55mph. I find it hard to believe that I'm not using more fuel at 3000 RPM (75/80 MPH) than I am at 2100 (55 MPH). With the O/D, I can run the same 75/80 MPH at my current 55 MPH RPMs. Dale McIntosh TC Gold #92/ACES #1709/NECOA #41 67SS/67 Elky Dales Place My 67 SS and 67 El Camino ChevelleStuff Decoding info on 64-72 Chevelles Team 67 1967 Chevelle/El Camino Specific Midwest Chevelles Midwest Chevelle Show Information
