727 valve body
Anyone know if there is a way to convert a regular 727 valve body to a manual? Someone told me that it is possible but I never heard of this being done.

Just as easy to get one professionally done by TCI. www.tciauto.com You wont find any better at auto trannies. If it's a street car, for safety reasons stick with a manual/auto VB.

the mopar chassis book tells all about it. it also gives part numbers... although they may be outdated.

TransGo and B&M both make kits to convert to full manual and retain the rear band apply for coast braking, these use a stock forward shift pattern as opposed to the normal reversed pattern.

I'm surprised no one has brought this up yet.
Is this a street or strip car? I've read in several books that using a full manual valve body for street use is NOT recommended. Do some reserach before buying. TCI or TransGo would be my choices. 0.02c |

What I said was "For a street car, though...". Others have expressed the same thoughts, i.e. on a street car stay away from the totally manual shift valve body. |

I myself am no tranny expert but I have heard and seen alot about Auto transmissions. IMO I don't think you need a full manual valve body, it isn't necessary and is a danger when used in everyday driving conditions. If you really want a good valve body you should look at the auto/manual valve bodys. You can still grab a lower gear on demand and still keep the use of the automatic feature which is ALWAYS a bonus for those cruises down the open road (arm out the window) LOL!!

The admonition against running MVB's on the street is based on a couple of things.
Most reverse MVB's don't apply the rear band in 1st, this isn't about coast braking since a fully auto doesn't apply the band in 1st when in Drive, it only applies in manual 1st. This is a safety factor because the rear band takes some of the load off of the sprag which is a weak point, failure of the sprag often leads to transmission explosions. MVB's are now available that apply the rear band in 1st so that is no longer a safety concern but another concern is the constant use of the rear band which wasn't intended to be used on every shift cycle. Constant use will accelerate wear on the band. One problem with running the low band apply MVB is that the car must be at near a dead stop when shifting down to 1st, otherwise there is a objectionable lurch as the band applies while coasting. This problem has been addressed by Turbo-Action which now offers a Cheetah MVB that has a delayed rear band apply to minimize the lurch. So, if you're willing to live with the accelerated rear band wear and the added wear on the shift linkage, there's no reason to not run a MVB on the street. |

Good info, John. I was not aware of the newer types of MVB's.
(Though I didn't say so, the Cheetah MVB I'm using is in my bracket car.) |
