Will I have to shorten the drive shaft with a TH400?  How will I know how much?  Will the machine shop know exactly what to do?   Lojac ----- Original Message ----- From: Mark Weber To: [EMAIL PROTECTED] Sent: Monday, March 25, 2002 10:33 PM Subject: RE: [Chevelle-List] Four Speed to Automatic Lojac, The TH400 and TH700 are different lengths. You will need to shorten the drive shaft if you go to a th700. Not sure of the length, people will tell you to "measure your car".  The trans tunnel on the pass side at the firewall will need to be dented in a bit for clearance with a TH700. Not a big deal but a mod was required on my 1971. The trans cross member needs to move if going from a TH400 to TH700. There were existing holes in my frame I used. It sounds like some frames have correct holes and some people can use one existing hole and drill another on each side. The TH400 trans cooler lines I purchased work on my TH700. If you go from a three speed auto on the floor to a 4 speed, you can change the console face plate and shift detent plate to one for the 4 speed. Year one sells the kits, I think they are about $100.   Mark -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Cecil "Steve" Martin Sent: Monday, March 25, 2002 7:22 PM To: [EMAIL PROTECTED] Subject: RE: [Chevelle-List] Four Speed to Automatic Hey Lojac,                  I am about to convert from Auto-Magic on the column to  �4 on the floor�. Want to swap some parts? It has a TH350 in there right now. I am in Ohio.                                                           Steve   -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Lojac Sent: Sunday, March 24, 2002 10:49 PM To: [EMAIL PROTECTED] Subject: Re: [Chevelle-List] Four Speed to Automatic   Is this an easy swap or complicated?  I have been doing some reading on the web about having to shorten the drive shaft because of the length of the TH400.  Is this true?  I was also wanting to use a TH700....is this any different from doing the swap with the TH400???   Thanks, Lojac
